  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. This will last until February 28, 2200 of the Gregorian Calendar.
  193 2214 Rosh Hashanah will fall on October 6 for the first time.
  218 2239 September 30 The Year 6000 begins in the Hebrew Calendar.

  10,868 June 10, AD 12,892 In the Hebrew calendar, due to a gradual drift in relation to the solar year, Passover will fall on the northern summer solstice (it has historically fallen around the spring equinox).
  18,850 AD 20,874 The lunar Islamic calendar and the solar Gregorian calendar will share the same year number. After this, the shorter Islamic calendar will slowly overtake the Gregorian.[1]
  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]
