Nope! 1,000 years ago the Christian church(s) had the "East West
Schism", resulting in Orthodox Christianty in the east, and
Catholic/Prodestant Christianity in the west. The 2 sides often disagree
about when Easter is.

As far as I can tell the `opening_hours` syntax on the wiki doesn't 
specify which easter, but I presume it refers to the locally observed 
easter.
