Yom Kippur (Day of Atonement) (יום כיפור (Hebrew)). Region: Israel and Jewish communities worldwide. Tradition: Judaism. Calendar: Hebrew calendar (Tishrei 10; begins the evening before). Dates: Israel and worldwide (begins the previous evening) 2026: Monday 21 September 2026 [official, source IL]; Israel and worldwide (begins the previous evening) 2027: Monday 11 October 2027 [official, source IL]; Israel and worldwide (begins the previous evening) 2028: Saturday 30 September 2028 [official, source IL]. History and significance: Yom Kippur is the holiest day of the Jewish year, a day of atonement and repentance. Observant Jews fast for about 25 hours and spend much of the day in synagogue prayer. In Israel public life comes to a standstill, with no traffic or broadcasting. It closes the Days of Awe that begin at Rosh Hashanah. Key rituals and foods: 25 hour fast, Kol Nidre evening service, Neilah closing prayer, white clothing; a festive meal breaks the fast.
