Why is Easter movable?

We all probably noticed that Easter is a holiday that falls on different days every year. It usually falls in April, when nature awakens to life, like the Risen Christ Christ. However, why is Easter movable? Why isn't there a fixed week during which they will have location of each year's Holy Week celebrations? The following text will help you find the answer to this question.

Tradition has it that Christ was crucified on the 14th day of the month of Nisan. The Israelite calendar was different from that of the Roman Empire (Julian), so a specific date had to be set so that Christians could celebrate Easter together. At the Council of Nicaea (325), it was agreed that the feast would be celebrated on the first Sunday after the spring full moon. Hence the differences in the specific date of celebration of the Easter liturgy.

In the 16th century, the Julian calendar was replaced in Europe by the Gregorian calendar. As a result of this change, there was a rift between the celebration of the Resurrection by the Church Roman Catholic and Orthodox. The latter celebrates this holiday about two weeks later, moreover, it is faithful to the old tradition to always celebrate Easter later than the Jews celebrate Passover. As is well known, Jesus Before his death, he instructed his disciples to prepare the Passover, so his death must have come later.
