The Jewish New Year is called Rosh Hashanah. It is a two-day celebration that usually falls during the month of September or October and marks the start of the Jewish calendar year. During this time, Jewish people gather to pray, reflect on the past year, and ask for forgiveness for their sins. It is also a time for people to make resolutions and commitments for the upcoming year. The shofar, a hollowed out ram's horn, is blown during Rosh Hashanah to signify the start of the new year.
