It won't happen again until the year 79811. That's 77,798 years from now. So if you're Jewish, enjoy the moment.
I'm referring to the concurrence of Thanksgiving and Hanukkah. Some American Jews are calling it Thanksgivukkah.
Actually Hanukkah begins on the Wednesday evening before Thanksgiving, which this year falls on Nov. 28. It's a rare occasion for Jews to celebrate two holidays at once, one uniquely American - Thanksgiving - and the other singularly Jewish.
