Yes, and Passover this year will begin April 19th with
Orthodox Easter on April 27th, the last day I believe it can
be under that calendar.
In connection with Iain Pears' *An Instance of the
Fingerpost*, I did some research into the calculation of
Easter before the Gregorian Calendar and under it. Easter
is now sort of as you say it is. Under the Julian Calendar,
the calculation of Easter was mind-bending. See
http://www.ortelius.de/kalender/east_en.php
But the actual Gregorian calculation is not much better.See
the same site. They note that the short cuts are generally,
but not always accurate.
What I am not quite sure of is why Passover and Orthodox
Easter are so off this year? Are both of them still
applying the old Julian calculations? I thought that when
Russia converted to the Gregorian calendar in 1918, the last
holdout had been eliminated.
I would be glad to hear the explanation for this year's
discrepancies.
