    This is a good breakdown of the reasons for the differences: What’s the Difference Between Easter and Orthodox Easter?

    Long story short, Easter is found by calculating the first Sunday after the first full moon falling on or after the vernal equinox. The Western church (Catholics and Protestants) use the modern Gregorian calendar to find this date, whereas the Eastern church (Orthodox) use the old Julian calendar, ensuring that Easter (we call it Pascha) falls after the Jewish celebration of Passover.

    Some Orthodox traditions, primarily the Russian Orthodox, use the Julian calendar for the Nativity as well, and celebrate Christmas on January 7.
