The Orthodox calendar

Every canonical Orthodox church calculates Pascha the same way. Pascha, Great Lent, Ascension and Pentecost therefore fall on the same day for Greeks and Russians alike — there is no disagreement there at all.

The difference is only in the fixed feasts, the ones tied to a date rather than to Pascha. Churches on the Revised Julian or New Calendar — the Greek tradition, the Antiochians, the OCA, most parishes in North America — keep the Nativity on December 25. Churches on the Julian calendar — Moscow, Jerusalem, Serbia, Georgia and Mount Athos — keep the very same feast thirteen days later, which lands on January 7 by the civil reckoning. The feast has not moved. The civil date has.

Use the switch above to see either reckoning. Neither is presented here as the correct one.
