Movable Russian Orthodox Holidays: These holidays depend on Easter, which is determined by the first Sunday after the first full moon on or after spring equinox. The Russian Orthodox Church calculates this lunar event according to the Julian calendar which is 13 days later than the Gregorian calendar used throughout the world. Thus, the "fixed church" holidays are 13 days later than their Western counterpart, but Easter is either one Sunday later or (rarely) five Sundays later. The rest of the movable holidays are adjusted accordingly.
Velikiy Post - Lent (Ash Wednesday) (7th Wed. before)
Verbnoe Voskresene - Palm Sunday (Sun. before)
Paskha - Easter
Voznesenie Gospodne - Ascension (40 days after)

Den Svyatogo Dukha - Holy Spirit Day (51 days)
