About Yom Kippur

Yom Kippur, the Day of Atonement, is the holiest day of the Jewish year. It comes on 10 Tishrei, ten days after Rosh Hashanah, in September or October. Adults go without food or water for about 25 hours and spend much of the day at synagogue. It starts with the Kol Nidre service the evening before and ends with Neilah and one long blast of the shofar.

In Israel almost everything stops, from TV and radio to traffic on the roads. It is not a US federal holiday, though New York City public schools and some other districts close.

How this is calculated

Each midnight takes one off the number. Today is left out and the day itself is counted, so tomorrow shows as 1 day away. Clock changes for daylight saving make no difference.

In Excel or Google Sheets, type =DATE(2027,10,11)-TODAY() into a cell to get the same count; add 1 to include today.

Counted from Friday, October 16, 2026 (US Eastern time). When you open the page, it counts again from the date on your device, so it matches your own day.
