Thanksgivukkah

Thanksgivukkah is a holiday name portmanteau neologism given to the convergence of the American holiday of Thanksgiving and the first day (and second night) of the Jewish holiday of Hanukkah on Thursday, November 28, 2013. It was the result of a rare coincidence between the lunisolar Hebrew calendar (whose dates reflect both the moon phase and the time of the solar year, and which can have between 353 and 385 days per year) and the Gregorian calendar. Because the calendars are not calculated the same way, Hanukkah appears at a different time each year on the Gregorian calendar.
