What date is Easter 2018, how’s the date decided and why does it change every year?
While the dates for Christmas, Valentine’s Day and Halloween are fixed, Easter can fall any time between March 22 and April 25
Why does the date of Easter change each year?
In Western Christianity, Easter Sunday must always fall on the next full moon after Spring Equinox.
Easter can fall as early as March and as late as April or May, depending on the year and calendar used.
Christians in the east who use the Julian calendar instead of the Gregorian calendar may have a different date.
The date of Easter changes because the full moon can fall on different days in different time zones.
