A Brief History of the Reformed Orthodox Calendar


Easter Calculations

The following table lists the years up to 2100 when the date of Reformed Orthodox Easter does not coincide with the date of Gregorian Easter. In these calculations a longitude of 35º 10' East of Greenwich was adopted for the meridian of Jerusalem.

The Adoption of the Reformed Orthodox Calendar

Several of the orthodox Churches, however, did eventually agree, though not all at the same time, to adopt the New Calendar. These were the Churches of Constantinople, Alexandria, Antioch, Greece, Cyprus, Rumania, Poland, and most recently, Bulgaria (1968).

However, not all orthodox Christians have adopted the Reformed Orthodox Calendar. Several groups, collectively known as the “Old Calendarists” or the palaioemerologitai, such as the Churches of Jerusalem, Russia and Serbia, along with the monasteries on Mt. Athos, still continue to adhere to the Old (Julian) Calendar.

The Orthodox Churches which have adopted the New Calendar observe Christmas with the other Churches of Christendom on December 25; the Orthodox Churches which have not adopted it celebrate Christmas 13 days later, on January 7. Epiphany is celebrated by the former on January 6 and by the latter on January 19. And so it is with all the great feasts of the Christian Calendar but one. Easter, the feast of feasts, continues to be calculated by all Orthodox Churches to the dates of the Old Calendar. Consequently, all Orthodox Churches observe the event of Christ’s Resurrection on the same day, regardless of when the rest of Christendom does. An exception to this general rule is the Orthodox Church of Finland. Owing to the fact that it makes up less than 2 per cent of the population of a predominantly Lutheran country, it observes Easter according to the New Calendar for practical reasons. It may well be that the date of Orthodox Easter occasionally coincides with that of the other Christian Churches; however, it may also occur as much as 5 weeks later. Thus arose the formula applied by the Orthodox Churches adopting the New Calendar – viz., that immovable feast days are to be observed 13 days earlier than in the Old Calendar, while Easter and all movable feast days dependent on it are still calculated according to the Old Calendar – which was seen as a compromise with those who opposed the change. On the one hand, the necessary revisions were made to correct the Old Calendar; on the other hand, the calculation of Easter was retained as before so as not to violate the holy canons. Nevertheless, this compromise was to prove incapable of preventing the schism of “Old Calendarists” which ensued.

As is always the case with reform movements, there was strong opposition to the adoption of the New Calendar, especially in Greece. What differed in this situation, however, was that reform was initiated by the established Church together with the total backing of the state. Groups of “Old Calendarists” or palaioemerologitai, refused to abide by the Church’s decision and continued to follow the Old Calendar for both movable and immovable feast days. The basis of their refusal to abandon the Old Calendar rested on the argument that canons ratified by an Ecumenical Synod knew only of the Julian Calendar. Therefore, nothing less than an Ecumenical Synod had the authority to institute a reform of such proportion. In view of their refusal to submit to the authority of the Church of Greece, they were excommunicated by the official Church. This was not the case with the monasteries of Mt. Athos. Although all but one (i.e., 19 monasteries) continued to follow the Old Calendar, they are under the jurisdiction of the Patriarchate of Constantinople with which they continue to be in communion. Despite attempts by the civil authorities in Greece to suppress them, the “Old Calendarists” continue to exist there and abroad and to maintain a hierarchy of their own together with parishes and monasteries.
