Happy Hannukah! Happy Thanksgiving!

As everyone has heard by now, for the first time ever (or the first time since 1899 or 1863 depending who's counting) the first day of Hannukah and Thanksgiving coincide.  I thought this picture encapsulated the coincidence very nicely. 



Here's what I wrote on my Happy Hannukah post on my own blog about the calendaric calculations:

This year, 5774 according to the Jewish (lunar) calendar, Channukah coincides with the American Thanksgiving holiday. This is a confluence that hasn't happened for over 100 years and won't happen again for thousands of years to come. From the link:
The Jewish month of Kislev can currently start as early as November 3 or as late as December 2, which means that the first day of Hanukkah can come as early as November 28 or as late as December 27.

The reason for the broad range of possible dates is that the Jewish calendar is lunar-solar. The months are based on the cycles of the moon. But the calendar changes the lengths of those months, and even how many months are in a year, to make sure that Passover always falls in the spring. This complex system — put in place by Rav Shmuel in the first half of the first millennium CE — ensures that the Jewish date and the secular date match up every 19 years. (By contrast, the Muslim calendar is purely lunar, which is why Ramadan can fall during any time of the solar year. The Christian religious calendar is almost entirely solar, but Easter falls on the first Sunday after the first full moon after the spring equinox [around March 21], a calculation that involves the moon as well as the sun.)

Because of this Jewish 19-year cycle, 19 years from now, in the year 2032, Hanukkah will again fall on November 28. But Thanksgiving in that year falls three days earlier, on the 25th.

On average, we would expect the 19-year Jewish cycle and the 7-year Thanksgiving-on-November-28 cycle to coincide about every 19x7 years, which is to say, approximately every 133 years. And they sort of do.

One-hundred and fifty-two years ago, in 1861, the first day of Hanukkah and the 4th Thursday in November were both on November 28th. But there was no Thanksgiving back then.

[...]

The Shmuelian calendar and the Gregorian calendar have been diverging at the rate of about 11 minutes a year, or 3 days every 400 years.

[...]

This is why (remember the question from several paragraphs ago?) in the year 2165, when we'd expect Thanksgiving and Hanukkah to coincide again, Hanukkah will actually be one day later.

And that is why Thanksgiving and Hanukkah will never again coincide.

Well, almost never.
Read the rest of the fascinating calculations and historical explanations.

In case you thought it a wonderful thing for our two nations to share a holiday once in a lifetime, you would be mistaken. Well, not really. Here's a hilarious spoof from Israeli journalist Matthew Kalman who writes about the outcry as Israel steals Thanksgiving:

(Tehran, September 28) IRAN’ S SUPREME LEADER called on the international community to condemn what he described as “an outrageous act of cultural imperialism by the Zionist enemy” – the hijacking of Thanksgiving by the Jewish state.
[...]
 “Is it Hanuka, Channukah or Honecker?” demanded Khamenei to roars of approval. “No-one even knows how to spell the damn thing!”
“We say to the Zionists: Take your filthy oil-based foodstuffs to the wintry days of December, where they belong, and allow our American allies to celebrate their genocide of the Native American Homelanders without interference!” he added.
The Iranian leader was addressing thousands of ordinary Iranians who had come to bathe in the heavy water facility at Arak as part of a Plutonium Peace Party organized to celebrate the recent Geneva agreement under which Iran will be allowed to slaughter as many people as Bashar Assad.
LMAO! Read the whole thing. :-D


So in celebration of the joint festivities, nicknamed "Thanksgivukah" by some bright sparks, I bring you a wonderful, bouncy, catchy music video by Ari Lesser, the Orthodox Jewish reggae star who made a name for himself with his anti-BDS "boycott Israel" video:




May we continue to have much to be grateful for, and may we not forget to Whom we owe our thanks.

Happy Hannukah and Happy Thanksgiving everyone!

  2. Thank you for the wonderful post annie!

    Calendar systems are cool, and maddening... weirdest story I ever hear regarding one was this one... one of those conspiracy theories which are kinda compelling, because some aspects check out...

    Any way, happy (Ch|H)ann?ukk?ah!

    1. Wow! I thought our calculations were complicated!

      But this:

      The primary motivation for the Gregorian calendar reform was that the date of Easter was slowly slipping (reaching about ten or eleven days by the 16th C.) towards summer. This date is sometimes loosely defined as the first Sunday after the first full moon after the spring (a.k.a. vernal) equinox (which, as astronomer Duncan Steel has stated, implies that Easter can occur any time between March 22 and April 25).

      ...they stole from us (the Jews). The whole purpose of our "luni-solar" (or looney solar?) calendar is to keep Passover in the spring because it says in the Torah that Passover must fall "in the month of spring".

      Someone (can't remember who) in the Jewish world recently calculated that even with our 7 leap years (each time adding a 13th month) in a 19 year cycle, Passover is slowly sliding towards winter, and at some point in the next 100-150 years we are going to have to add an extra leap month to keep it in the spring.

      I wonder how it will pan out.

  3. Wonderful post Annie! My family and I were talking last night about Chan..Hann..er, however it's spelled falling on Thanksgiving. My youngest brother was incredulous that it wouldn't happen again for thousands of years, lol. I'll have to show him this post (although he's not a geeky as all of us here, so his eyes may glaze over). ;)

    Thanks to whoever placed the menorah at the top of the sidebar. Very festive! I love it! :)

  4. Wonderful post, annie! I loved "Israel steals Thanksgiving".

    The Iranian leader was addressing thousands of ordinary Iranians who had come to bathe in the heavy water facility at Arak as part of a Plutonium Peace Party organized to celebrate the recent Geneva agreement under which Iran will be allowed to slaughter as many people as Bashar Assad.

    LMAO!!!

    I'm glad we could share the festivities. Happy Hanukkah!
