Hoshana Rabbah is the seventh day of the Jewish festival of Sukkot, which usually falls in late September or early October. It is a day of prayer and reflection, marking the conclusion of the High Holy Days that begin with Rosh Hashanah and continue through Yom Kippur. On Hoshana Rabbah, special prayers called Hoshana are recited, asking for divine mercy and blessings for the coming year. Many people also participate in a ritual involving the willow branches, symbolizing the hope for rain and abundance. The day is significant for its themes of judgment and redemption.
