Apparently - according to those who know - Xmas is not so much an abbreviation as a regression to the Greek way of saying things - but I don't spika da lingo let alone classical Greek.

So Xmas it is PAL - and I don't think the trenches cared for the difference either.

Another factoid that I can't remember the source of is the story of fraternization on Xmas day of waring soldiers. It was known in other conflicts in Europe before WW1 - but I can't recall which ones.
