| Christianity
is the world's biggest religion,
with about 2.2 billion followers worldwide. It is based
on the teachings of Jesus Christ who lived in the Holy
Land 2,000 years ago.
In Western Christianity, Easter
falls on a Sunday from March 22 to April 25.
“….Easter Day is the first Sunday after
the full moon that occurs next after the vernal equinox,
is not a precise statement of the actual ecclesiastical
rules. The full moon involved is not the astronomical
Full Moon but an ecclesiastical moon (determined from
tables) that keeps, more or less, in step with the astronomical
Moon.
The ecclesiastical rules are:
-
Easter falls on the first Sunday following the first
ecclesiastical full moon that occurs on or after
the day of the vernal equinox;
-
this
particular ecclesiastical full moon is the 14th
day of a tabular lunation (new moon); and
-
the vernal equinox is fixed as March 21 and this
resulting in that Easter can never occur before
March 22 or later than April 25. The Gregorian dates
for the ecclesiastical full moon come from the Gregorian
tables….”
