Orthodox calendar 2004

Notes

1. How Easter is calculated
2. Orthodox feasts: immovable and movable
3. Days of the remembrance of the departed
4. Orthodox fast

1. Easter is calculated using Gauss formula. a = [(19 * [Y / 19] + 15) / 30], where Y - year, [] - residue of division;
   b = [(2 * [Y / 4] + 4 * [Y / 7] + 6 * a + 6) / 7];
   If (a + b) > 10 then Easter is (a + b - 9) of April (old calendar) else (22 + a + b) of March (old calendar). Thus the date of Easter can be from 22.03 to 25.04 (old calendar) or from 04.04 to 08.05 (new calendar).
