Yes it is....I heard or read somewhere that in 1967 the calander for Pascha(easter) was going to be changed in celebrating with the Roman calander which is the new one(gregorian) and the light did not come..and so it was left as it is known to all Orthodox..
Has anyone here experienced the Holy Fire? My Godmother who was born in Bethlehem experienced the Holy Fire and she said it was flying around everywhere lighting people's candles.
