First day of Chanukah on Christmas

Posted on by

As many have noted, the first day of Chanukah coincided with Christmas this year (December 25, 2016).

This happens approximately three times each century. Prior to this year, the most recent occurrence was in 1978, and the next time this will happen will be in 2027.

For completeness, here are the co-occurrences of the first day of Chanukah and Christmas during the past 400 years:

And here are the next two hundred years:

Yom HaAliyah / יום העלייה

Posted on by

We’ve added a new modern holiday, Yom HaAliyah (יום העלייה). Yom HaAliyah recognizes Aliyah, immigration to the Jewish State of Israel.

More info from Wikipedia:

Yom HaAliyah (Aliyah Day) (Hebrew: יום העליה) is an Israeli national holiday celebrated annually on the seventh of the Hebrew month of Cheshvan, to commemorate the historic events which happened on the tenth of the Hebrew month of Nisan (Hebrew: י’ ניסן). The holiday was established to acknowledge Aliyah, immigration to the Jewish state, as a core value of the State of Israel, and honor the ongoing contributions of Olim to Israeli society.

The holiday was first observed on 7 Cheshvan 5777 (November 8, 2016).
