WE will eventually reform the calendar. 2023 & 2029 can be the transition years.

The current calendar system is over complicated and should be reformed.

The Basic WEcalendar is a much better calendar system.

A calendar is a system of organizing days for social, religious, commercial, administrative purposes. However, the current civil calendar is over-complicated that actually confuses our memory and wastes our time, effort, and resource to cope with the annual altering calender system. A simple single-year calendar applicable for any year should be practically easy and perfect for all strata of society, including governments and businesses.  

What if the New Year's Day and the New Year's Eve are always on Sunday?

In the common year, there have 52 weeks and 1 remaining day giving the total 365 days. If a common year begins on Sunday, the year will end on Sunday accordingly. It will be the best arrangement to let both the New Year' Day and the New Year's Eve always on Sunday. Then all years can use the same simple calendar without any redundant annual change of the calendar.  

What if a year has exact 52 weeks?

A year has 52 weeks plus 1 or 2 days. The remaining 1 or 2 days actually complicate the calendar system. The concept of "Long Week" with 8 days per week (which includes two Sundays) can fix that issue. Only 2.4% weeks per year are "Long Weeks" that can ensure exact 52 weeks per year. The whole calendar system can then be simplified and it is practically good for all strata of society.

The Basic WEcalendar is the most practical civil calendar.

Perennial Calendar

The Baic WEcalendar inherits the months from the current calendar. It briefly combines the first 9 months of 2012 and the final 3 months of 2017, and then it repeats annually. This repeatable single-year calendar can keep the same dates, weeks, months, and other calendar features applicable for any year.

Consistent & Practical

A year has consistent 12 months and 52 weeks. All quarters of the year always begin from Sunday with exact 13 weeks in 3 months. Both the New Year's Eve and the New Year's Day are always on Sunday. It is the most practical calendar for all strata of society, including governments and businesses.

Leap Day = September 30

The Basic WEcalendar retains all existing 366 dates of the year, but the Leap Day is switched from February 29 to September 30 (Sunday). That can maintain 91 regualr days in the first and third quarters. Thus, February always has 29 days. September has 29 days in the common year and 30 days in the leap year.

Double Sunday

"Double Sunday"  means a special Sunday with two consecutive days. It exists naturally when a month beginning from Sunday follows the prior month ending on Sunday. Double Sunday effectively maintains exact 52 weeks per year, because the remaining one or two days after 52 weeks are relevantly combined as Double Sundays.  

Annual Double Sunday

"Annual Double Sunday" is the combination of the New Year’s Eve and the New Year’s Day of the next year. Both days are Sundays. It is an excellent and applausive Sunday arrangement. On the Sunday of New Year's Eve, people can celebrate, take rest, or worship on Sunday.  On the Sunday of New Year’s Day, people can also celebrate and welcome the New Year. 

Leap Year Double Sunday

During the Leap Year, the "Leap Year Double Sunday" is the combination of the Leap Day (September 30) and the first day of October. Both days are Sundays. It makes sure the irregular Leap Day will not affect the normal weekday sequence of any day. Hence, the annual calendar renewal is unnecessary. All years can maintain exact 52 weeks.

Moreover the Balanced WEcalendar can be the best alternative

The Balanced WEcalendar is extended from the Basic WEcalendar. In order to maintain all months with either 30 or 31 days, it removes July 31, adds February 30, and sets the Leap Day on March 31. It can retain the existing 365 dates of the year and offers all benefits of the Basic WEcalendar. Because of the balanced arrangement of all month lengths, it is very tidy and even more practical.

Removal of July 31

In order to maintain all months with either 30 or 31 days, the Balanced WEcalendar needs to remove July 31 and add February 30. The third quarter will have regular 91 days or exact 13 weeks. July 31 is neither a national day nor a special memorial day.

February always with 30 days

Since February 30 is added, the first quarter will have 92 days. The Leap Day will be set on March 31.  Thus, the Leap Year Double Year is the combination of the Leap Day (March 31) and the first day of April. In the history, February 30 was a real date.

WEcalendar is the most rational advancement and the best enrichment of the calendar system.


In the history, there happened many calendar reforms. In every century, there were several proposals of calendar reform. However, since the vast expansion of our population after the World War II, people consider that the calendar system is inalterable although there are significant deficiencies to be corrected. Moreover, there are three major challenges that make the calendar reform impossible. They include the enormous cost justification for any calendar reform, the difficulty of adopting a new calendar system by all people, and the objection from the religious groups. Rigorously, WEcalendar is the balanced solution with the least changes and lowest transition cost, the easiest learning and simplest adoption, as well as the highest respect to the religious groups and their belief.   

 With intensive study and analysis of the calendar development, all known proposals of calendar reform, the contemporary calendar usage, as well as going through multiple prototypes and experiments, WEcalendar is the most practical perennial calendar that can retain our accustomed calendar features. Actually, there are two proposed versions of WEcalendar. The basic version can retain all existing 366 dates of the year but February has 29 days only. The balanced version retains the existing 365 dates only so as to ensure all months having either 30 or 31 days. Both versions follow the same design principles and offer the same benefits. All quarters of the year always begin from Sunday with exact 13 weeks in 3 months. Both the New Year’s Day and the New Year’s Eve are always on Sunday. Although it looks alike the current calendar without any noticeable changes, it can actually generate countless benefits from the well-organized and consistent structure. The proposed transition year is either 2023 or 2029 because the year of 2023 will begin from Sunday and the year of 2028 will end on Sunday.

 Although we have used the Gregorian calendar in our life, the drawbacks should eventually be fixed because it is over-complicated and the most expensive system that we use daily. It was actually designed neither for this modern era nor for the nations with different culture and religion. It means the calendar should eventually be reformed. The proposed Basic WEcalendar and the alternative Balanced WEcalendar introduce the lease changes and the minimum transition impact. They are effectively more practical for any government, business, culture, and religion.  Please feel free to share and discuss the calendar reform issues with your family and friends. Everyone can participate into the studies and discussion. We have the right to choose the right calendar for us and our generations.
