Why is Easter on a different Sunday each year?

The date of Easter is determined by the moon cycle, specifically the first full moon following the vernal (spring) equinox (also known as a ‘pink’ moon). According to the traditional method used by the Church, Easter Sunday falls on the first Sunday after this full moon, which means the date can vary each year between March 22 and April 25. This system is based on the lunisolar calendar, similar to the Hebrew calendar, which is why Easter often aligns closely with the Jewish holiday of Passover. The use of the moon to determine Easter dates connects the Christian celebration to ancient traditions and ensures that it reflects both seasonal and spiritual cycles.
