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

Least Transition Impact

Best Transition Year

2023 can be the transition year, because the year will start from Sunday. Since there are 5 or 7 months are identifcal to the current calendar, people will intuitively understand how to transit and use it. User adoption are certainly simple and easy. In fact, any year starting from Sunday or Monday is good for the transition.

Existing Clocks & Watches


All existing clocks and watches are generally usable in the age of WEcalendar, because WEcalendar inherited the months directly from the Gregorian calendar. However, for those clocks and watches with non-adjustable Leap Day or pre-programmed day of the week, such as some digital timepieces, there will have several date adjustments in different periods so as to make the correct display of dates and the day of the week.

Almost Zero Impact

Effectively, almost nobody will lose their birthdays, all current publications and documents are not affected, and all present or past event dates are always valid without any conversion. It also means all existing birth certificates, identity cards, passports, visas, and etc. are definitely valid after the transition. It is because WEcalendar inherits the months directly from the current calendar and retains the existing 365 or all 366 dates.

Other Transition Issues

Regarding the software and computer systems, all date related functions and features should be upgraded to comply with WEcalendar. Since the only two differences are the day of the week and the changed Leap Day, the upgrade ought to be straightforward. 

Moreover, those date-related libraries of major programming languages will be upgraded and available in the open source software libraries, such as Github.com, for supporting and facilitating the software upgrade. With our intensive experience gained from the Year 2000 software upgrade, the software change due to this calendar reform solely with functional changes should be fairly manageable and affordable. 

It may be a concern that people will prefer their birthdays being in the weekends instead of weekdays; especially we can change the natural childbirth through scheduled caesarean or scheduled induction. In order to balance the dates of birth and make it fair to all people, countries may establish a new Labour Law of Birthday Leave so that employees are entitled to a day of paid leave on their birthday if the birthday is on a working day. Then, people can always enjoy their birthday in a holiday.

Of course, there are still more issues to be resolved. We successfully transited to use the Metric System, although there were radical changes. We certainly can adopt and transit to use WEcalendar, because it only introduces the least changes. Anyone can intuitively understand WEcalendar without any training. The transition to WEcalendar should certainly be manageable, affordable, and with significant long-term economic benefits.
