Thanksgiving is almost here in the US, and this year falls on the 25th of November (55525), exactly one month before Christmas (55555). I was thinking about this a couple of nights ago, and was wondering when Hanukkah was this year, when I noticed that there was a full moon in the sky above me. I remembered Jon Stewart singing on A Colbert Christmas a couple of years ago (54793) that the Festival of Lights also starts "On the 25th." ("Of December?" "Kislev." "Which is when, exactly?" "I will check.") Since the full moon falls on the 15th day of Jewish months, that means that the holiday must follow in ten days, which would be the night of 1 December (55531/2). We don't really celebrate, since there are no kids left, but I'll probably bring home some gelt. That's all three holidays falling on the 25th of some month.
I just noticed while writing this that Christmas falls on Modified Julian Day 55555, which is another reason to celebrate, I guess.
I think it's funny that some people get upset if they hear "Happy holidays" instead of "Merry Christmas", because Christmas is not the only holiday. We have not only Christmas, Thanksgiving and Hanukkah, but also New Year, which most people celebrate regardless of their religion. I suppose somebody must celebrate Kwanzaa, too. ("What would it be like without Kwanzaa? Like every year before 1966.") If we were to be really accurate, we should mention all of them, but that would take forever, so why not just lump them under "holidays"? It's not meant necessarily to avoid offending non-Christians, and I don't why people want to do that, but it's to include the other holidays we all celebrate in this country, i.e. Thanksgiving early in the season, and the New Year later.
