  79 2100, March 14 March 14 (which will be February 29 in the Julian calendar), the difference between the Julian calendar and the Gregorian calendar reaches 14 days. Since 14 is divisible by 7, this will be the first time in history since its inception that the Gregorian calendar has the same day of the week for each day of the year as the Julian calendar.

  25,000
The Tabular Islamic calendar will be roughly 10 days out of sync with the Moon's phases.
  46,877 March 1, AD 48,901[note 1] The Julian calendar (365.25 days) and Gregorian calendar (365.2425 days) will be one year apart.[2]
