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).
