Jerusalem Day commemorates the capture and reunification of Jerusalem during the Six-Day War (on 28 Iyyar 5727 on the Jewish calendar—June 7, 1967), after which Israel gained possession of the Old City of Jerusalem and other Arab lands. Although there are no specific rituals connected with this holiday, it is common to recite the Hallel (Psalms 115-118), Psalm 107, and the Aleinu, or concluding prayer. Because this day falls during the Lag ba-Omer period, the mourning customs traditionally observed during this time are suspended for the day. Discuss
