My friend Lisa Popick Coll offers this version of a Thanksgivukkiah on Facebook.
Reportedly the two holidays will not coincide for another 70,000 years. More or less. The explanation:
The overlap this year is because according to the Jewish calendar, this is a leap year, meaning that an entire extra month is added to the calendar. Because of that, most major Jewish holidays moved up by nearly a month. Couple that with the extremely late date of Thanksgiving in 2013, and you've got a convergence of holidays that comes once in many, many generations.
