Dear All,
Those of you who have studied the great noon marks in
Italy and elsewhere will know their importance in the
reckoning of the date of the Vernal Equinox and, hence,
the Date of Easter.
This year Easter is unusually early which begs the
questions: How unusual? Can it be earlier?
Over the 5,700,000-year Easter Cycle, Easter falls on
23 March 54150 times, less than once a century. After
this year, Easter will next fall on 23 March in 2160.
The earliest date that Easter can fall is 22 March and
that is also the rarest date, occurring 27550 times in
5,700,000 years. The next occasion is 2285.
The latest date that Easter can fall is 25 April and
this occurs 42000 times in 5,700,000 years. The next
occasion is 2038.
The most common date is 19 April, which occurs
220400 times in 5,700,000 years. The next occasion
is 2071.
For further details, see the table following my
signature. Meanwhile...
Happy Palm Sunday
