This year (and this year only) the first night of Hanukkah, the Festival of Lights, falls on... Thanksgiving (okay, it's starts sundown on Thanksgiving Eve, but the first full day is on Thanksgiving. Hanukkah is a Jewish holiday celebrated for eight days and nights. It starts on the 25th of the Jewish month of Kislev, which coincides with late November-late December on the secular calendar. This holiday commemorates the re-dedication of the holy Temple in Jerusalem following the Jewish victory over the Syrian-Greeks in 165 B.C.E.) Yes, this year, we'll be seeing turkey-shaped menorahs ( created by a nine-yr old in New York), recipes for pumpkin challah bread and other Jewish/Thankgiving food and a giant driedel in the Macy's Thanksgiving parade ( which I'm find very interesting, I might be working into my 2 and 3 yr old story time just this once. I'm not even Jewish!)
According to a lot of articles on the web ( including Wikepedia), this is only the second time to ever happen ( the first time was 1888, but it may have happen way before Thanksgiving was declared a federal holiday by President Lincoln in 1863.) The next time this will happen ... might be a long, long time ( possibly the year 79811). Why? Well, the Hebrew calender and the Gregorian calender do not always calculate the same way ( and I'm not going to try to explain here, so have fun looking up yourself.)
Here are some websites to help you get in the Thanksgivukkah spirit ( even if you're Jewish or not):
