Easter's date is determined by the moon due to its basis on the ecclesiastical approximation of the March equinox. Historically, Easter is celebrated on the first Sunday after the Paschal Full Moon, which is the first full moon on or after March 21. This system was established by the Council of Nicaea in 325 AD to standardize the celebration of Easter across the Christian world, ensuring it falls after the spring equinox and aligns with the biblical account of the crucifixion and resurrection of Jesus.
