Why Does Easter Come On A Different Different Sunday Every Year?

Easter comes on a different Sunday of the month because the date is determined in following manner. Easter is the first Sunday after the first full moon (some say the first ecclesiastical, or the first astrological, full moon which comes on the day or after the vernal equinox. The full moon is on the 14th day of a full moon and the vernal equinox is normally, March 21st. Easter can never be celebrated prior to March 22 nor later than April 25th.

In AD 325 (after the death of Christ) the Council of Nicea was convened and ruled all churches should celebrate Easter on the same day. Today, there is a trend to give up this formula and set a specific Sunday as Easter Sunday. For instance the recommendation is to set the Second Sunday of April as Easter Sunday.
