Anniversary page-March 1st, 2021

Today is Monday March 1st, 2021, this year’s March 1st is on a Monday like 1300, 721 years ago, they removed leap day of 1300 and replaced it with the first day of March, so now the whole 14th century is a repeat of the 8th century in calendars for all years. This is how they removed leap day from 1300:


 * “it’s almost the end of February as most calendars will switch to Gregorian within the next couple centuries, so can we remove leap day of this year, 1300, to not remove too many days in 1 Year in the future?”(they have already done that to existing countries... our country named the United States wasn’t formed until 1776 with the first full year being 1777, which is why we’d always use Gregorian from 1100/1300 and so on, and exactly of how I displayed calendars and holidays before that year using the Julian calendar).
 * ”sure”
 * ”there, leap day is gone for this year”
 * ”thanks, now can we remove it for 1400 & 1500?”
 * ”certainly”

now the next century being the 15th century is a repeat of the 10th century in calendars as the 16th century is a repeat of the 12th century.
