As far as I have understood, there are different traditions concerning the calendar in orthodox churches. Most common is the old Julian one, or what?
The Finnish orthodox church follows the gregorian one as does the luttheran and catholic churches. So there three churches are calebrating for instance the easter in the very same day.
Is the Finnish orthodox church a rare exeption in the orthodox tradition?
To my knowledge the Finnish church is the only Orthodox Church that uses the Gregorian paschalion, the New Calendar churches, such as my own, using the New Calendar only for the fixed dates.
