Easter's date changes every year because it is determined by the lunar calendar, not the Gregorian calendar, which most of the world uses today. Specifically, Easter is celebrated on the first Sunday after the first full moon occurring on or after the vernal equinox. This calculation can lead to Easter falling anywhere between March 22 and April 25. In contrast, Christmas is fixed to December 25th on the Gregorian calendar, commemorating the birth of Jesus Christ, and thus does not change annually. This difference in calculation methods explains the varying dates of Easter compared to the fixed date of Christmas.
