Zerowedgie puts in perhaps the most likely possibility for replacing Pope Gregory's taxation calendar: https://en.wikipedia.org/wiki/Gregorian_Calendar https://www.history.com/news/6-things-you-may-not-know-about-the-gregorian-c... 12 months of 30 + 30 + 31 day months (JFM, AMJ, JAS, OND), for a 364 day year, and an extra 7 day week ~ every 6 years, at the end of the 'year'. Benefits include no leap days/months, each month is the same number of days every year, New Year's day is always the same day of the week, as is every other holiday - and so the time spent planning which days of the year are holidays, and which days of the week they should fall on, can be reduced to "decide once and be happy thereafter" and with the concomitant benefit of only every having to print one calendar once, reusing it every year.
