The Council of Nicaea (A.D. 325) reached a final settlement on the date by decreeing that Easter must be universally celebrated in the Christian world on the Sunday following the fourteenth day of the paschal moon, whose fourteenth day followed the spring equinox. The Roman Church adopted a cycle of ninety-five years for determining the date of Easter, and the remaining hold-outs, the Celts finally conceded and gave up their cycle of 532 years in the ninth century.it is a calender that shows all the Christan events like Christmas,Easter,St.pathricks day.
