I always wish people Happy Holidays. That said, I certainly wish you and yours a very happy Christmas. Christmas is wonderful--"it's the most wonderful time of the year" the song goes--but it's not the only holiday. There's New Year's Day, my son's birthday, my birthday, and if you're Greek, you get another Christmas and New Year's Day a week later. Not that I'm Greek, but I know some Greek people--Okay, they became US citizens a few months ago but they're still "greek to me" and we visit them on their Christmas as well. I usually take off work from about December 15 till around January 23, and it's one long holiday season. I like for it to be happy, and I like for others to be happy as well, not just on December 25 but for the entire season, so I always wish them "Happy Holidays."
Here's the image I will project on the screen in the lecture hall when we finish the statistical thermodynamics course at the end of next week:
Cheers!
In my Greek Orthodox church we use the 25th. I"m surprised there's a Greek church there using the 7th of January. Now the Serbian and Russian Orthodox churches are still using the 7th and I never expect that to change.
The Greek's do follow the old calendar for Easter though.
