יום העלייה

Yom HaAliyah, or Aliyah Day (Hebrew: יום העלייה), is an Israeli national holiday celebrated annually according to the Jewish calendar on the tenth of the Hebrew month of Nisan to commemorate the Jewish people entering the Land of Israel as written in the Hebrew Bible, which happened on the tenth of the Hebrew month of Nisan (Hebrew: י' ניסן).[1] The holiday was also established to acknowledge Aliyah, immigration of Jews to the Jewish state, as a core value of the State of Israel, and honor the ongoing contributions of Olim, Jewish immigrants, to Israeli society. Yom HaAliyah is also observed in Israeli schools on the seventh of the Hebrew month of Cheshvan
