Yom Yerushalaim, or Jerusalem Day, is observed in Israel on the 28th day of the Hebrew month of Iyar, commemorating the liberation of the Western Wall and the Old City during the Six-Day War. This public holiday celebrates the reunification of Jerusalem, which had been divided between Israel and Jordan following the First Arab-Israeli War. The Israeli government proclaimed Jerusalem Day in 1968, and it became a national holiday in 1998. Celebrations typically include memorial services, state ceremonies, and a large parade through downtown Jerusalem. The Chief Rabbinate of Israel has ruled that the entire Hallel be recited with blessings to mark the regaining of access to the Western Wall, Israel's holiest shrine.
