mental arithmetic simplicity. Therefore, the wobble is essentially a curiosity that is of no practical or ritual concern. Adoption The new calendar has been adopted by Orthodox churches as follows: 1923: Estonia (accepted the Gregorian calendar, including the Gregorian Paschalion, but in 1945 joined the Moscow Patriarchate and reverted to Julian; after re-establishing in 1996, the Estonian Apostolic Orthodox Church adopted the Revised Julian calendar in 2012) 1923: Finland (uses the Gregorian calendar, including the Gregorian Paschalion) 10/23 March 1924: Constantinople, Cyprus and Greece 1/14 October 1924: Poland (Very few parishes changed - on 2/15 June 2014 the Church switched back, but individual parishes may use the Revised Julian calendar if they wish) 1/14 October 1924: Romania 1/14 October 1928: Alexandria and Antioch The Albanian Orthodox Church became autocephalous on 12 April 1937 7/20 December 1968: Bulgaria Adopting churches are known as New Calendarists.

A solution to this conundrum is to hypothesize that it was accepted only by the short-lived schismatic Renovationist Church, which had seized church buildings with the support of the Soviet government while Patriarch Tikhon was under house arrest. After his release, on , he declared that all Renovationist decrees were without grace, presumably including its acceptance of the new calendar. Defense The basic justification for the new calendar is the known errors of the Julian calendar, which will in the course of time lead to a situation in which those following the Julian calendar (in the Northern Hemisphere) will be reckoning the month of December (and the feast of Christ's Nativity) during the heat of summer, August and its feasts during the deep cold of winter, Easter during the autumn season, and the November feasts in the springtime. This would conflict with the Church's historic practice of celebrating Christ's birth on , a date chosen for a number of reasons. One of the reasons mentioned by Bennet is the time of the winter solstice, when the days begin to lengthen again as the
