Of all the things the Pilgrims couldn’t foresee while celebrating that first Thanksgiving — Black Friday sales, SpongeBob getting his own balloon in the Macy’s parade, gluten-free stuffing — we can safely add "Thanksgivukkah" to the list.
2012 (earliest)
We’re still 24 hours away from Thanksgiving 2012, but it’s never too early to start thinking of next year, right? Apparently not, at least, not for the folks behind Thanksgivukkah. You see, next year Thanksgiving falls on the first night of Hanukkah, and well, "Thanksgiving" + "Hanukkah" = "Thanksgivukkah". Get it?
The earliest citation is the first print reference, but it should be noted that the Thanksgivukkah Facebook page was created by Dana Gitell on November 15, 2012. For the record, she also received a U.S. trademark for the term on July 26, 2013.
