What Yom Kippur Is About

Yom Kippur is known as the Day of Atonement and is considered the holiest day in the Jewish year. Many Jews spend the day fasting, praying, and reflecting on their actions over the past year.

Common practices include:

  • A 25–26 hour fast from food and drink.
  • Attending synagogue services throughout the day.
  • Seeking forgiveness from others and from God.

A simple example: someone might call or message friends and family before Yom Kippur to apologize for any hurt they caused, then spend the day itself in prayer and quiet reflection.

Why the Date Moves Each Year

  • Yom Kippur is fixed as 10 Tishrei in the Jewish (Hebrew) calendar.
  • The Hebrew calendar is lunisolar, so the corresponding Gregorian date shifts each year.

That’s why in 2023 it fell on September 24–25, while in other years it can be in late September or early October.

TL;DR: Yom Kippur 2023 was on the evening of Sunday, September 24 through the evening of Monday, September 25 (10 Tishrei 5784).
