*The [[Gregorian Calendar]] churches are: [[Church of Finland|Finland]] and [[Church of Estonia|Estonia]].

A number of the above churches also have some parishes which are on a different calendar than their respective [[primate]]s, most especially the Ecumenical Patriarchate of Constantinople in the [[diaspora]], which has many Julian Calendar parishes. In terms of population, most Orthodox Christians follow the Julian Calendar, but in terms of numbers of autocephalous and autonomous church bodies, the majority use one of the New Calendars (Revised Julian or Gregorian).
