The "High Holidays," also known as the High Holy Days, are a significant period in the Jewish calendar, encompassing Rosh Hashanah and Yom Kippur. Rosh Hashanah, the Jewish New Year, marks the beginning of a ten-day period of reflection and repentance, culminating in Yom Kippur, the Day of Atonement. During these days, many Jews engage in prayer, self-examination, and community gatherings. Traditional customs include sounding the shofar, a ram's horn, during Rosh Hashanah and fasting on Yom Kippur. These observances emphasize themes of renewal, forgiveness, and spiritual growth.
