   Not really.   
      
   The calculation is purely based on dates (unlike, say, some versions of   
   the Islamic Calendar).  Gregorian Easter was decided in Rome, Julian in   
   Bithynia; they might well have calculated for the date of the nominal   
   Moon as seen at Jerusalem.   
      
   It's essentially an integer calculation, and the result repeats every   
   5,700,000 years.   
      
   In AD 314, the Council of Arles decided that the same date should be   
   used everywhere (but not what that date would be).   
      
   I have an algorithm derived, almost completely, from the Calendar Act   
   via the Prayer Book; that's the true authority for many of us, including   
   in the USA.
