Which year will have 53 Saturdays?
Every 28 years should have five years with 53 Saturdays if the period does not involve a century year not divisible by 400. Any year starting on Saturday will have 53 Saturdays, such as 2005, 2011, 2022, and 2028 from 2001 to 2028. Moreover, any leap year starting on Friday will have 53 Saturdays. 2016 was the leap year starting on Friday, and the next leap year starting on Friday will be 2044 after 28 years.
-
Do you know a year can have either 52 or 53 weeks?
Which year will have 53 weeks?A Gregorian calendar year can have 52 or 53 weeks. If you guess the leap year has 53 weeks, it is wrong. In ISO-8601, every 28 years should have five years with 53 weeks if the period does not involve a century year not divisible by 400. Any year starting on Thursday will have 53 weeks, such as 2004, 2009, 2015, and 2026 from 2001 to 2028; any leap year starting on Wednesday will have 53 weeks, such as 2020 and 2048.
-
Which year will have its four quarters starting on the same day of the week?
No year can have its four quarters starting on the same day of the week in the Gregorian calendar. A quarter must have exactly 91 days or 13 weeks to cause the next quarter to begin on the same week-day. In the leap year of the Gregorian calendar, the first two quarters have 91 days (i.e., 13 weeks). Thus, only the first three quarters can start on the same week-day. In the common years, only the second quarter has 91 days. The second and third quarters can start on the same week-day. While the first three quarters has 273 days (i.e., 3x13 weeks), the first and the fourth quarter can start on the same week-day. But they are different from the second and third quarters.
-
Why was the leap day assigned to February, the shortest month in a year?
Around 713 BCE, February was the last month added by Numa Pompilius. Along with the Roman age, February was a short month with various lengths, and it finally had 29 days. Under the reform into the Julian Calendar around 46 BCE, February 29 became the leap day until now. Julius Caesar also promoted January and February as the first two months of the year, which arbitrarily made the New Year start in the middle of Winter instead of Spring. The calendar does not anchor to any astronomical position for the start of a year. Rationally, the leap day should be the final day of a year, like a leap second is the last second in a day. At least, the leap day shall be the final day of a long month (i.e., 31 days) instead of the shortest month.
-
Why are 12 months of the year with uneven days?
Is there any astronomical reason?No astronomical reason supports irregular month lengths, but the months can never have equal days. Months with 29 or 30 days follow the moon cycle of 29.53 days. Later, months with 30 and 31 days as one-twelfth of a year. However, the distributions of 30 and 31 days were somehow arbitrary or for some religious beliefs. It was unexplained why only February has 28 days shorter than the minimum 29 days. Even surprised, the calendar does not intend to align months with weeks, quarters, or seasons. The uneven months without any alignment bring us much inconvenience and confusion. All proposals for calendar reform suggest new month structures with equal month length or some rational patterns that ensure every year with the same calendar without annual renewal. Because of the thousand-year linkage of history, cultures, and traditions into the existing month structure, it seems unaffordable to alter the calendar. None of the proposals was accepted. Thus, we have to keep the irregular months until now.
-
Which year will start on Monday?
In the Gregorian calendar, four years will start on Monday within 28 years if the period does not involve a century year not divisible by 400. By searching the period from 2001 to 2028 on the Internet, 2001, 2007, and 2018 began on Monday, and the leap year 2024 will also start on Monday. For the next 28 years, we can deduce that 2029, 2035, 2046, and 2052 will begin on Monday.
-
Which year will your birthday fall on the same week-day you were born?
In the Gregorian calendar, it takes 5, 6, or 11 years to bring your birthday on the same week-day you were born. The pattern of either 5, 6, or 11 years will continue. Moreover, we usually do not remember the week-day we were born. Only a few people know the start week-day of any month and year, so nobody can work out which year will have their birthday fall on the same week-day they were born.
-
Which year will have three Fridays falling on the 13th day?
Friday the 13th is an unlucky day in Western superstition. The 13th day of the month falls on a Friday at least once and up to three times a year. Any month that starts on “Sunday” will have the 13th day on Friday. A total of 688 Fridays fall on the 13th day every 400 years. The average frequency is 1.72 per year. Any leap years starting Sunday will have three Fridays falling on the 13th day of January, April, and June, such as in 2012. Any non-leap year starting Thursday will have three Fridays falling on the 13th day of February, March, and November, such as 2009, 2015, and 2026 from 2001 to 2028. Thus, 2037, 2040, 2043, and 2054 will have three Fridays falling on the 13th day in the next 28 years.
-
Can you remember the school term dates of any school year?
Although school schedules are logically equal yearly, the calendars for school terms are different. Because of the annual calendar renewal with varying weeks, all schools must annually revise their schedules to follow the changing calendars. Almost nobody can remember the school term dates of any school year, and we need to mark the school dates in our paper or digital calendars. All calendrical research and studies suggested that new calendar proposals should be perennial and applicable to any year. A simple calendar consistently with fixed weeks for any year will be practical and suitable as our civil calendar. Then, the school term dates of every school year will be the same and reusable for subsequent years.
-
Do you know a year has an average of 365.2425 days?
Is it astronomically accurate?A solar year is approximately 365.242189 days long, though its length changes little over time. The current calendar was a calendar reform in 1582 to correct the unexpected drift of the Julian calendar, which had 11 days drifted off in the past 1580 years. Since the Gregorian calendar skips three leap days of the Julian calendar every 400 years, the year has an average of 365.2425 days (i.e., 365.25 minus 3/400). Although the Gregorian calendar still has one day drifted off by three thousand years, the accuracy is acceptable. However, it is stiff that every 400 years must be 20,871 weeks. It is impossible to have further skips of leap day as a calibration for new astronomical observances. Nothing is constant in the Universe, while everything is evolving and changing. The current observed year length may not be equivalent to the future year lengths. Thus, an accurate calendar system should allow the skip of leap day for new astronomical observances of the Earth's Orbit. The Gregorian calendar is infeasible for any calibration.
Why calendar upgrade?
Uneven, Unexplained & Confusing!
Don't worry if you are not sure of the answers. 99.99% of people cannot tell the start week-day of the coming months and years. We all rely on paper or software calendars. Why do people know very little about the calendar? Why did we not learn that from school? Since the current calendar has irregular month lengths and can start from any day of the week, it is complicated, unexplained, and likely incomplete. Because of its confusing and irrational design, the Gregorian calendar is not an easy teaching topic. No school included it in the teaching syllabus. The calendar as our daily system could and should be as simple as the clock system instead of complicated and confusing. Nevertheless, we learn the general calendar usage from our parents or seniors, and then we dogmatically follow and use it in our life.
Why Wasting Effort, Time & Money?
Our complicated calendar inherited its messy history. In brief, the ancient Roman calendar started with just ten months a year. January and February were the last appended months. Julius Caesar changed them to the first and second months of the year. He somehow changed New Year's Day from the start of Spring in March to the first day of January in deep Winter. The Gregorian calendar slightly reformed the Julian calendar by skipping three leap days and fixing 20,871 weeks every 400 years. The reform had no intention to align the weeks with quarters, seasons, or the year, thus derivated 14 versions of calendar years. Then, we must renew the calendar annually from one of its 14 versions that trouble people and businesses forever. The calendar should have a better structure to suit our daily use. Overall, it always confuses our memory, wastes our effort, and spends our resources on its annual variations. Such a complicated calendar system should not be our daily system in this modern age.
Waiting for Upgrade...
The calendar seems incomplete because of its weird month lengths and annual change. While I taught my little son to read and use the calendar, many irrational calendarial structures and designs made me unable to explain. There were many attempts and better proposals for calendar reform, but all failed. They suggested new month lengths, different month structures, or using leap weeks instead of leap days. The proposed calendars were simple but not feasible for transition. Their new calendar structures will mess up all existing documents and computer systems. Conversion of the difference in dates will be unavoidable, and the enormous transition cost will never be affordable.
The Weeky Calendar is a viable proposal because it is compatible with the current calendar and ensures the same 52 weeks applicable to any year. As a result, no annual calendar renewal will happen again. The dates of both calendars will be identical but different in the day of the week. The adoption is simple and at no cost. It will be the only feasible calendar upgrade waiting for your adoption.
Do you know how our calendar system inherited its messy history? Why didn't we improve or upgrade our calendar so far?
In 1582, the Gregorian calendar was instituted as a simple reform of the Julian calendar, which skipped three leap days and fixed 20,871 weeks every 400 years.
Since the transition to the Gregorian calendar had to correct the drifted eleven days of the Julian calendar, Britain deleted eleven days in September 1752.

Same 52 Weeks for Any Calendar Year
The Weeky Calendar is much more people-friendly and business-friendly. It defines the same 52 weeks for any calendar year and eliminates annual calendar renewals. The consistent 52 weeks are more practical for people and the best practice for any business. The 52 weeks are divisible into 13 quad-weeks (i.e., 13x4 weeks) for some particular usages. Because the same calendar applies to any year, no confusion and waste will happen again. That saves much money and effort. We may fix the dates for those holidays and observances currently without designated dates, such as Father's Day, Mother's Day, and Easter Sunday. Annual planning will be simplified and easily repeated onwards. Parents, students, and teachers will be glad to see the school terms and breaks falling on equal dates every school year, so they can easily plan for school schedules and term-break activities. The simple perennial calendar can give us better memory and save money.
Quarterly 13 Weeks, Monday to Sunday
The Weeky Calendar ensures all quarters with exactly 13 weeks from Monday to Sunday. It successfully aligns the current 12 irregular months into four quarters and each quarter with 13 weeks. A Thursday is reserved for February 29 as a leap day to keep the first quarter having 91 days in 13 weeks. The third and the fourth quarter have 92 days which is 13 weeks plus one extra day. The Weeky Calendar resolved them by an Extra Saturday and Extra Sunday. We are generally happier on Saturday or Sunday because these days are for gatherings, hobbies, family, leisure, or worship. The Extra Saturday and Sunday give us extra happiness.
An Extra Saturday is on September 1 after the Saturday of August 31 to form a happy long weekend for people. It may be a special worship day for any religion on the first day of a new season. December 31 is the final day of the year. It is logically set as an Extra Sunday after the Sunday of December 30 to have a happy long weekend at the end of the year. Again, the Extra Sunday can be a special worship day on the last day of the year. Religions will have equal or more days for people to attend church.
Complete, Consistent, Versatile & Perennial
Besides incredible conveniences and money savings for all people and businesses, the standardized and consistent 13 weeks per quarter make monthly, quarterly, and yearly statistics, comparisons, and forecasts more relevant. Their usages, including the Weeky Days, are versatile. For example, the apparent difference between the 10th Thursday (March 7) and the 28th Friday (July 12) is 18 weeks and one day or 127 days. As it is a seamless upgrade of the current Gregorian calendar into a simple perennial system that effectively serves our daily needs, the uneven months of the Gregorian calendar will no longer be trouble.
Since the Weeky Calendar is 100% compatible with the Gregorian calendar and can run in parallel, they follow the same leap years. There will have no date conversion. With the subtle extensions of Extra Saturday and Extra Sunday, people will intuitively know how to use this simple and pragmatic calendar. The Weeky Calendar is 100% free to adopt in a seamless transition. Schools, companies, organizations, and countries can easily afford this seamless calendar upgrade for its permanent benefits and savings. The Weeky Calendar is the most viable and best-ever calendar upgrade waiting for your support and adoption.
Weeky Calendar
= First 8 months of 2024 + Last 4 months of 2029

= Seamless Adoption + Permanent Benefits
Using the Weeky Calendar, we can also name a day by its week number, the day name of the week, and the year. E.g., the 4th Sunday of any year is equal to January 28, the 6th Wednesday to February 7, the 28th Friday to July 12, etc. We call them Weeky Dates.
Calendar reform will affect the thousand-year history, cultures, traditions, and religious beliefs linked with the calendar. Luckily, the Weeky Calendar treasures and retains these cultural and religious linkages by ensuring 100% compatibility with the current calendar. No business or work patterns will be affected, but just more simple and flexible. Using the Weeky Calendar, almost 100% of people know the start week-day of each month and the current week number of the year. It will be the most rational calendar upgrade. We should choose a versatile and hassle-free calendar as our daily civil calendar.

How easy is it to answer the above questions if the Weeky Calendar is adopted?
1. Which year will have 53 Saturdays?
All years have 53 Saturdays because there is an annual Extra Saturday on September 1.2. Do you know a year can have either 52 or 53 weeks? Which year will have 53 weeks?
The Weeky Calendar defines the same 52 weeks for any calendar year. No year will have 53 weeks.3. Which year will have its four quarters starting on the same day of the week?
The Weeky Calendar ensures all quarters consistently start on Monday.4. Why was the leap day assigned to February, the shortest month in a year?
It was a historical issue. Although February has 29 days in the leap year, it is still the shortest month. The Weeky Calendar reserves a Thursday for February 29. It ensures the first quarter has 91 days in 13 weeks. Eventually, the leap day should be the final day of the leap year. February 29 will be an ordinary Thursday, and December 31 will become a Leap Sunday in the leap year that occurs once at the end of the 4-year leap cycle. Such a simple switch of the leap day should be a perfect and seamless transition.5. Why are 12 months of the year with uneven days? Is there any astronomical reason?
No astronomical reason supports the months with uneven days, but the Weeky Calendar can align the 12 irregular months into four even quarters exactly with 13 weeks.6. Which year will start on Monday?
All years start on Monday.7. Which year will your birthday fall on the same week-day you were born?
Every birthday will fall on the same week-day we were born.8. Which year will have three Fridays fallin on the 13th day?
No Friday will fall on the 13th day because no month will start on Sunday.9. Can you remember the school term dates of any school year?
In the Weeky Calendar, schools can always use the same repeatable and reusable annual schedule. Teachers, students, and parents can easily remember and follow the same school calendar for any school year. That will be convenient for arranging activities, such as term-break special studies, multiple weeks of sports drills, overseas travels, etc.10. Do you know a year has an average of 365.2425 days? Is it astronomically accurate?
Yes, it is somehow accurate. The Weeky Calendar follows the same leap years as the Gregorian calendar. However, unlike the Gregorian calendar, it allows a skip of any leap year as a calibration based on the astronomical observances of the Earth’s Orbit.
Versatile
That will be much more useful and flexible than the current complicated and stiff calendar system. Here are some examples:
The Final State
The Weeky Calendar has three special days well-prepared for the seamless switch of the leap day.
As a result, it matches the Earth's elliptical orbit in that the first half-year is shorter by 1.25 days than the second half-year.
It means the first half-year takes around 182 days to orbit, and the second half-year takes about 183.25 days to complete the orbit.
February 29
February 29 is currently a Leap Thursday. It will eventually be a regular Thursday. Then the first quarter will have 13 full weeks.
September 1
September 1 is an annual Extra Saturday. It is the first day of a new season and will not be affected by the switch of the leap day.
December 31
December 31 is currently an Extra Sunday. It will finally be a Leap Sunday that will occur once at the end of the 4-year leap cycle.
* The leap day on December 31 will also reduce the 14 versions of the Gregorian calendar to just seven. It is equivalent to half the complexity.
* People born on December 31 (Leap Sunday) will find no difference to celebrate their birthday on December 30 since both days are Sundays.

Why is February shorter than the other months? Will it be better to make February with 30 days?
There is a common suggestion of extending February to 30 days for keeping all months with either 30 or 31 days without any exception, but that must remove one date from another month. It will certainly remove the 31st day of a long month. However, it will be a very long discussion to settle which date we can delete and to compromise from many arguments.
From the structure of the Weeky Calendar, we can remove the 31st day of May or August to make February 30 days, which also tries to make the second month of every quarter just 30 days. We may remove August 31, insert February 30, and set March 1 as an Extra Friday, but that cannot be justifiable for the significant transition efforts and its aroused confusion. As the arguments and chaos will have no differences in removing one or two dates, it will be much better to remove both dates and makes February 30 days and April 31 days. The resultant calendar structure will have 31 days for the first month of every quarter and 30 days for the second month of every quarter. It will be a simple and practical calendar structure similar to the almost adopted World Calendar proposed by Elisabeth Achelis of New York in 1930. We may call it Weeky Calendar 2 or World Calendar 2.

December 31 should still be Leap Sunday in the leap year after the last Sunday on December 30, while March 31 will be an Extra Sunday after the ordinary Sunday on March 30. Catholics and Christians may consider fixing Easter Sunday on the special March 31 instead of varying yearly. Unlike the Weeky Calendar, the new calendar structure is incompatible with the Gregorian calendar. Massive acceptance and transition will almost be hopeless. Could we eventually justify and adopt this ideal calendar structure?

Frequently Asked Questions
-
1. Will countries, the United Nations, and the Vatican consider any proposal for a calendar upgrade?
Yes, they should do it. The United Nations should discuss, assess, and accept any viable proposal for calendar upgrade. They almost approved the proposed World Calendar in 1955, but a veto from the government of the United States postponed the issue. The Second Ecumenical Council of the Vatican declared that the Vatican did not oppose efforts designed to introduce a calendar applicable to any year into civil society in 1963.
The latest adoption of the Gregorian calendar was in Saudi Arabia in October 2016. The approach to calendar reform is still being explored and discussed. There are still several active proposals for calendar reform. Although any calendar reform will cause chaos and the enormous transition cost will be unaffordable, the Weeky Calendar won't have such issues. It is 100% compatible and in parallel with the Gregorian calendar. Wikipedia about Calendar Reform stated, "If a proposed design is sufficiently close to the legacy one, i.e. compatible with it, a reform of the local calendar system is possible without disruption." The Weeky Calendar will be the only viable calendar upgrade that can seamlessly transform the current calendar into a perennial one and is still 100% compatible with the current calendar. -
2. Will it be fair for people born on a working day?
Birthday Leave is a common practice in many companies and countries, in which employees are entitled to a paid day of birthday leave on a working day. That will make sure all people may equally have a day off on their birthdays. The policy can even extend to the spouse. That ensures all days are good birthdays. It is also common for people to celebrate their birthday together on the weekend. By the way, the superstition of "Friday on the 13th day" will never exist in the Weeky Calendar. All days in the Weeky Calendar are good birthdays.
-
3. Why is Monday the first day of the week in the Weeky Calendar?
The Weeky Calendar follows the International Standard of ISO-8601, in which Monday is the first day of the week. The Gregorian calendar defined Monday as the first day of its 400-year cycle, in which the first day of 2001 was on Monday. Some countries, such as the United States, South America, and China, present the week on Sunday first. They practically treat every week starting from Monday for work and take rest on Sunday. The Weeky Calendar can show the weeks with either Sunday or Monday first. However, if the world compromises Sunday as the first week-day, Weeky Calendar will follow Sunday as the first week-day, and even the first month of every quarter will have Friday on the 13th day.
Countries can name the week-days according to their cultures or religions, in which people can work on the first five days and rest or worship at the weekend. Thus, Islamic countries and Muslims can name the week-days accordingly for praying on the sixth and seventh days and aligning with the working days of other countries and international financial markets. -
4. Which years are suitable for adopting the Weeky Calendar?
The Weeky Calendar is compatible with the current calendar using the same month structure. While we can use both calendar systems in parallel, we can use the Weeky Calendar whenever. For seamless transition without breaking the sequence in the days of the week, any years that start on Monday can be considered, such as the common years 2029, 2035, 2046, etc., and the leap years of 2024, 2052, etc. People will find almost no significant difference while transiting to the Weeky Calendar. Then, no further calendar renewal will happen again. People and businesses will significantly benefit from the simple and practical Weeky Calendar.

5. How easy is adding the new "Weeky Date" in the software program?
Weeky Date is the value-added feature of the Weeky Calendar that labels a day with the weekday name (Monday to Sunday), the week number (1 to 52) shown in superscript, and the year. "Weeky Day" is the Weeky Date without the year. We can easily add the new "Weeky Date" function in any software program. That explains how simple to adopt and transit to the Weeky Calendar. This webpage also contains the source code of the "Weeky Date" function in Javascript, which anyone can copy via "DevTools" of an internet browser. Here is an example of "WeekyDay" as an Excel VBA function usable in an Excel formula, such as the formula of "=WeekyDay(TODAY())" will give "":
Public Function WeekyDay(inDate As Date) As String Dim supNumber As Variant: Dim daysAhead As Variant: Dim weeksAhead As Variant 'Using the Superscripted numbers in the Unicode supNumber = Array(8304, 185, 178, 179, 8308, 8309, 8310, 8311, 8312, 8313) daysAhead = Array(0, 0, 3, 4, 0, 2, 5, 0, 3, 5, 0, 3, 5) weeksAhead = Array(0, 1, 5, 9, 14, 18, 22, 27, 31, 35, 40, 44, 48) Dim mth As Integer: mth = VBA.Month(inDate) Dim day As Integer: day = VBA.day(inDate) Dim dwi As Integer: dwi = (daysAhead(mth) + day) Mod 7 If dwi = 0 Or (mth = 12 And day = 31) Then dwi = 7 With WorksheetFunction Dim dow As String dow = .Text(DateSerial(year:=2001, Month:=1, day:=dwi), "ddd") If ((mth = 9 And day = 1) Or (mth = 12 And day = 31)) Then dow = dow + .Unichar(8314) Else Dim wks As Integer wks = (daysAhead(mth) + day - dwi) / 7 + weeksAhead(mth) If wks < 10 Then dow = dow + .Unichar(supNumber(wks)) Else dow = dow + .Unichar(supNumber(Int(wks / 10))) dow = dow + .Unichar(supNumber(wks Mod 10)) End If End If End With WeekyDay = dow End Function -
6. How was the Weeky Calendar initiated and rigorously designed?
In 2018, when I taught my eight-year-old son how to read the calendar in Auckland, New Zealand, he intuitively asked me several simple questions. Why is February the shortest month? Why is August a long month? He also asked why we renew the calendar annually and whether the months relate to astronomical observance. Ironically, no textbooks answered those questions. I started researching calendar systems and found that the Gregorian calendar was not designed to follow astronomical observances but was somehow arbitrary. The annual calendar renewal is the worse calendar design with many debates, which is annoying, inefficient, and redundant. It confuses our memory, wastes our continuous effort, and spends resources dealing with the annual calendar variations.
However, we seem to have no solution and just dogmatically follow the selected Gregorian calendar. There were trials of using different calendar systems and many proposals for calendar reform. All research and studies suggested the abortion of the annual calendar renewal and adoption of a perennial calendar system. However, none were accepted because those proposals introduced different days for weeks and months that could seriously affect all documents and computer systems. For instance, there are seven days a week with four weeks a month and 13 months a year, six days a week with six weeks a month and ten months a year, etc. Some proposals suggested a leap year with a leap week instead of a leap day for leap shifting so that a general year has only 364 days and a leap year has 371 days. It is inconsistent and inconvenient by the significant shift of seven days in the leap year. It seems the resulting simple calendar is just another way of complexity. As a result, while the transition is unaffordable, the adoption is impossible.The Gregorian calendar changes annually because it must align 365 or 366 days into the seven-day weeks. Thus, a year has 52 or 53 weeks. The ISO Week-numbering year has 364 and 371 days instead of the usual 365 or 366 days. If each date in the year has its fixed day of the week, no annual renewal will happen again. The Weeky Calendar is compatible with the Gregorian calendar by retaining all dates and ensuring the year with just 52 weeks. Initially, we used a prototype named as NexCalendar to collect feedback and opinions. Having taken five years of rigorous studies verified by thousands of people of different ages, religions, and backgrounds, we published the Weeky Calendar in January 2023. It is the most viable calendar upgrade. All people, businesses, organizations, and countries can afford such a seamless and affordable calendar upgrade. The advantages and benefits are permanent and forever.

7. How is the Weeky Calendar compliant with religious beliefs?
The Weeky Calendar is compatible with the Gregorian calendar. Only the weeks are standardized and subtly extended by an Extra Saturday and an Extra Sunday to ensure every quarter with consistent 13 weeks. The Weeky Calendar is much complete and structured in perfect harmony. The subtle changes will not affect the thousand-year history, cultures, traditions, and religious beliefs linked with the calendar. Religions may relevantly arrange the Extra Saturday and Sunday as extra worship days.
Nowadays, we know that 29.53058 are the mean days of the lunar months in the lunar cycle, and 365.24219 are the mean days of the solar years. Their orbits are independent and hard to align into weeks. It takes around 19 years for them to meet in the same position. Both year and month are never dividable by seven. The creation of the Universe (God) did not astronomically apply the whole number of seven as we expected. Since the seven-day week is imperfect with astronomical facts, the Weeky Calendar makes it a perfect fit with the subtle enhancements of Extra Saturday and Extra Sunday. It also benefits religions to have equal or more days for people to attend church.
Early Romans used eight-day weeks in civil practice for centuries before Emperor Constantine established the seven-day week in 321 CE. The mix of some 8-day weeks and 7-day weeks existed in the age of Jesus Christ. The Bible did not argue there were some eight-day weeks, the eighth-day Sabbaths, etc. The Weeky Calendar rigorously ensures the same 52 weeks for any Gregorian calendar year, which benefits all people, businesses, religions, and future generations. The Extra Saturday and the Extra Sunday can be extended worship days that present "higher respect" to any religion than keeping the confusing annual calendar renewal and its clunky calendar variations.
We deserve a rational calendar.
"Our World is changing. We must rethink our futures together." We have the right and obligation to choose a suitable calendar system that is simple and pragmatic. Weeky Calendar is the most rational and viable upgrade to ensure compatibility with the Gregorian calendar, which we can accept and adopt anytime. It is challenging to disseminate this proposal to all people. We sincerely need your support and involvement.
Your Support
We know very little about the current calendar even though it is our daily system, as we just dogmatically follow and use the calendar. If you know its messy design and troubles, will you question why we keep using such a weird calendar without any revision?
For us and future generations, we should tell our friends, families, relatives, neighbours, classmates, colleagues, and anyone that the Weeky Calendar is the only viable upgrade to our weird calendar, which can make our calendar to be much simple, more practical, versatile, and rational. The seamless transition will ensure no negative impact on anyone and any business. People will love to know that the Weeky Calendar can work compatible and parallel with the current calendar. The Weeky Calendar is familiar, pragmatic, memory-friendly, people-friendly, business-friendly, and money-saving, which benefits all people and businesses. Your support is highly essential.
Your Sponsor
There are plenty of ways to support and sponsor the Weeky Calendar. You may initiate and sponsor campaigns and advocacy activities anywhere. You may offer us some souvenirs, such as T-shirts or cup mugs. With the Weeky Calendar printed on the T-shirts or cup mugs, they will be permanently usable because the Weeky Calendar is applicable in any year.
We hope to disseminate the proposal for this essential calendar upgrade and explain the benefits of the Weeky Calendar in universities, associations, public forums, etc. Besides using the internet as the media, we won't have enough resources to arrange advocacy campaigns for all countries. Your contribution and sponsorship are necessary. Eventually, we wish some or all countries to adopt the Weeky Calendar as their civil calendar. Please let us know if you may help us to realize this mission.
