@Sviatogor The Bulgarian church follows the Gregorian calendar, so like Greece, Romania etc. we celebrate Christmas on the 25th of December (and Yordanovden/Bogoyavlenie (with the diving for the cross) on the 6th and Ivanovden on the 7th of January). I think only the Russian circle and Serbia celebrate it on the old date, according to the Julian calendar. And maybe the Armenians as well.
