From sundown on Tuesday, October 9 to nightfall on Wednesday, October 10, 1951. 10 Tishrei 5712 · יום כיפור Yom Kippur ( YOM kip-OOR, YAWM KIP-ər, YOHM-; Hebrew: יוֹם כִּפּוּר Yōm Kippūr [ˈjom kiˈpuʁ], lit. 'Day of Atonement') is the holiest day of the year in Judaism. It occurs annually on the 10th of Tishrei, in late September or early October. For traditional Jewish people, Yom Kippur centers on atonement and repentance. The day's main observances consist of full fasting and asceticism, both accompanied by extended prayer services (usually at synagogue) and sin confessions. Some minor Jewish denominations, such as Reconstructionist Judaism, focus less on sins and more on one's goals and accomplishments and setting yearly intentions. Alongside the related holiday of Rosh Hashanah, Yom Kippur is one of the two components of the High Holy Days of Judaism. It is also the last of the Ten Days of Repentance.
