wow! that does get to the meat of the matter.
even in the states?
Yes. But the major feasts (Christmas, Theophany, Pascha, etc.) correspond to the Julian calendar, if that was what you were asking in your original post.
Indeed we are Old Calendar, and personally I like it, not for religious reasons, but because it grew up on me.
And it's pretty cool, because then, I can go attend Christmas liturgy at either Syrian or Indian churches (I'm not sure if Armenians celebrate on the 25th or they do Jan. 6th).
