The exact Easter day:
Easter and the holidays that are related to it are moveable feasts which do not fall on a fixed date in the Gregorian or Julian calendars which follow only the cycle of the Sun.
The date is offset from the date of Passover and is therefore calculated based on a lunisolar calendar similar to the Hebrew calendar.
No details for the computation were specified; these were worked out in practice, a process that took centuries and generated a number of controversies.
It has come to be the first Sunday after the ecclesiastical full moon that occurs on or soonest after 21 March.
Even if calculated on the basis of the more accurate Gregorian calendar, the date of that full moon sometimes differs from that of the astronomical first full moon after the March equinox.
