the first day of HANUKKAH

It happened once in the past, but not during the lifetime of any living person.

And no person living November 28, 2013, will experience this rare event a second time.

In simple terms, Thanksgiving (the fourth Thursday in November) and the first day of Hanukkah occurred simultaneously this year—November 28th.

In a January 14, 2013 blogpost Jonathan Mizrahl, a Jewish American physicist, pondered and mathematically calculated how often this convergence occurs:

Thanksgiving is set as the fourth Thursday in November, meaning the latest it can be is 11/28. 11/28 is also the earliest Hanukkah can be. The Jewish calendar repeats on a 19 year cycle, and Thanksgiving repeats on a 7 year cycle. You would therefore expect them to coincide roughly every 19×7 = 133 years. Looking back, this is approximately correct – the last time it would have happened is 1861. However, Thanksgiving was only formally established by President Lincoln in 1863. So, it has never happened before… (Thanksgiving) originally it was the LAST Thursday in November.  This changed in 1942. If you use the last Thursday rather than the fourth Thursday, then the overlap has happened once before, in 1888.
