happy thanksgivukkah!

Happy Thanksgivukkah! Or Chanksgiving. I was totally blown away about how the convergence of Thanksgiving and the first day of Hanukkah won't recur for 70,000 years. (or ever?) It got me curious about the patterns of Thanksgiving and Hanukkah vs. the secular calendar, so I spent an hour or two this morning hacking out a little table. Thanksgiving is in brown, Hanukkah is in blue, Christmas in green, January 1 in red.

I was pleased to get a better feel for the patterns, the 4th Thursday's little day slide (with bumps on leap years), and Hanukkah's larger lunar moves. Still, looking at this 100 years of data, I would never have guessed that today is such a rare event...
