* Note that Western Christian churches specify that Easter will occur the Sunday after the first full moon after the vernal equinox. However Easter will not occur on March 23rd . According to the rule the vernal equinox is set to March 21st.no matter when it actually occurs, so Easter will occurs after the full moon on April 19th, namely April 21st. The Eastern churches still use the Julian Calendar and a more complex formula to calculate the date of Easter.
