(JNS.org) In light of the once-in-a-lifetime convergence of Thanksgiving and Chanukah, Boston’s retiring Mayor Thomas Menino has declared Nov. 28 to be “Thanksgivukkah” in the city. The proclamation notes the special “diversity of all its citizens” and the values embodied by both Chanukah and Thanksgiving, including “unity, hope and gratitude.”

Thanksgiving and Chanukah last fell on the same day in the late 19th century and is not expected to converge again for more than 75,000 years, making this year’s overlap special for American Jews who are usually accustomed to sharing the holiday with Christmas.
