When are Rosh Hashanah and Yom Kippur celebrated?

Answer 1

First, for those who wonder about the illustration, it is customary in Jewish homes to eat apples dipped in honey during the Jewish New Year (Rosh Hashanah). As for when the holidays of Rosh Hashanah and Yom Kippur occur, they generally happen at some time in September or even October. In 2015, the New Year began on September 13, for example; but in 2016, it will come later, beginning on October 2. The reason is this: Judaism uses a lunar calendar, so these holiday occur on different dates each year. However, the two holidays are linked: Rosh Hashanah (which comes first) begins the Ten Days of Repentance, a period of time that concludes with Yom Kippur (the Day of Atonement).

Answer 2

Rosh Hashanah is observed on the first two days of the Hebrew month of Tishrei.
Yom Kippur is the tenth day of the same month.

In 2016, those dates will correspond to October 3, 4, and 12 respectively.

In 2017, they will correspond to September 21, 22, and 30 respectively.
