It’s just what you’ve always wanted with your Thanksgiving dinner: a little math to go with your turkey, yams and potato pancakes.

Turkey latke, anyone?

They’re calling it Thanksgivukkah (some are, anyway), and it’s a rare alignment of Thanksgiving and Hanukkah. How rare? It hasn’t happened in more than 100 years, that much we can agree on. It might not happen again for 79,000 years, although that part of the equation is in dispute.

This smooth blend of holidays is happening this year; that’s what’s important. Call it Thanksgivukkah or don’t; that part is completely up to you.

“I’m not so sure I can spell that,” said Bertha Bodenheimer of Auburn’s Temple Shalom. “Or pronounce it.”

Not that Bodenheimer is hindered much by the awkward moniker. The Temple has a lot planned for the holidays, and the rare alignment makes it more interesting.

“We’re trying to figure out how to get potato latkes into the turkey,” Bertha said.

Food is where it’s at. There are traditional foods for Hanukkah — your latkes, your kugels, your brisket — and there are the regular fixings for Thanksgiving — turkey, yams, stuffing, all those things that make you tired and bloated at the end of the day. For many, bringing all those dishes together will be the challenge.

Here’s how a Thanksgivukkah planning session sounds.

“Luka wants to make a turkey menorah, which I’m fine with,” said Donna Young Eichenwald, who vacations in Maine but who will be eating her complicated holiday dinner elsewhere. “Husband mentioned something about sweet potato latkes, and that’s just not happening. Leo loves latkes, and I’m not messing with them! We’ll do a regular turkey, and I guess we can do brisket at the same time. But no kugels that day since we’re only four people. His Nana Thea’s Noodle Charlotte will wait until the next night.”

We’ll let Donna work that out. In the meantime, back to the weird mathematics that make this holiday special and a little confusing.

The people at, a Jewish lifestyle website, worked it all out so that the rest of us can save the lead in our pencils.

“Chanukah was declared a Jewish national holiday 2,178 years ago,” wrote Rabbi Tzvi Freeman of “Thanksgiving was declared a national American holiday on the last Thursday of every November by Abraham Lincoln in 1863. Before then, Thanksgiving was celebrated on different dates in different states, so we won’t count those. But, using the date converter, you will see that Thanksgiving coincided with the first day of Chanukah on November 29, 1888. It also coincided with the fifth day of Chanukah on November 30, 1899.

“On November 28, 1918,” Freeman continues, “Thanksgiving was on Chanukah eve. But since it’s still Thanksgiving until midnight, and Jewish days begin at night, that would still mean that Jewish Americans would have eaten their turkeys that Thanksgiving to the light of their first Chanukah candle.

“It gets more complicated,” Freeman wrote. “Originally, Thanksgiving was always on the last Thursday of November. In 1939, FDR decided it would be good for the economy to push Thanksgiving back a little, so he declared the fourth Thursday of that November to be Thanksgiving — even though there were five Thursdays to November that year. In 1942, that became federal law. But not all states went along with it. As late as 1956, Texas was still celebrating Thanksgiving a week later than the rest of the country. Which means that if you were a Texan Jewish family, you would be eating that turkey to the light of your first Chanukah light in 1945 and 1956.”

Some have calculated that the next Thanksgivukkah won’t happen for 79,000 years. The problem is that there are variables. Freeman, basing his math on certain assumptions, says it may happen again in 2070, when Thanksgiving falls on Hanukkah Eve.

“Can you imagine,” Bertha Bodenheimer said, “that someone bothered to figure all that out?”

In other words, let’s just eat.

For University of Farmington Professor Jonathan Cohen it’s a simple matter of mixing up the holiday schedule to keep everybody happy. Cohen, his wife and their family typically eat Thanksgiving dinner at night. This year? It can’t be done, not with that other holiday insisting on being observed.

“This year, we’ll have Thanksgiving dinner midday so we can do Hanukkah at night,” Cohen said.

In the Cohen family, there will be no attempts to mix turkey with latkes. That would be too difficult, and it remains unclear how it would taste. Better to have two separate meals to observe the holidays individually.

“It’s two different cuisines,” Cohen said.

The professor appreciates the congruence of holidays for reasons entirely unrelated to food. The alignment is so rare, people are talking about it, and some of them will be learning more about Jewish holidays.

“It’s kind of nice,” Cohen said, “because the non-Jewish will see Hanukkah as something independent of Christmas.”

At Temple Shalom, members and guests gather each night of the holiday on the back lawn of the synagogue to light the MegaMenorah, a 12-foot version of the lamp that usually sits in the windows of Jewish homes.

The public is welcome to join in the lighting at 5 p.m. on Wednesday for the first night, on Friday at 3:30 p.m. (earlier because of the Jewish Sabbath, which begins at sundown) and at 5 p.m. Saturday through Wednesday, Nov. 30 through Dec. 4. On Saturday, Monday and Tuesday evenings, there will be coffee, hot chocolate and doughnuts to share after the lighting. On Sunday, Dec. 1, following the lighting, Temple Shalom will celebrate its annual Hanukkah party.

Most of these things are traditional. There have been some changes, however.

Because of the unusual congruence of calendars, there will be no lighting of the MegaMenorah on the second night of the festival, Thursday evening, Nov. 28, which is Thanksgiving. Rabbi Hillel Katzir, the spiritual leader of Temple Shalom, decided to forgo the lighting of the MegaMenorah in the expectation that families will be enjoying Thanksgiving dinner that evening and so are unlikely to come out for the lighting — but the rabbi expects many Jewish families will instead be lighting their hanukkiyah (the special menorah for the holiday) at their Thanksgiving tables.

As for Bertha, it remains to be seen if she will experience a successful marriage of turkey and latkes. Unimportant, she said. No matter how novel this thing called Thanksgivukkah might be, it still encompasses the same old concepts.

“Holidays,” she said, “bring us closer together.”
