When is Yom Kippur 2027?
Yom Kippur 2027 is on Monday, 11 October 2027 — Monday. That is 334 days from today (11 November 2026) — 47 weeks and 5 days, or about 11.0 months. It is a Jewish observance. Jewish holidays begin the evening before the date listed.
How the countdown is worked out
The countdown is the number of days from today to the holiday's date: Monday, 11 October 2027 minus 11 November 2026 is 334 days. The count is in calendar days — it counts the days you have to wait, not the number of midnights, and it does not count today. The countdown timer recomputes the number live, second by second, and the days until calculator does the same calculation for any date you choose. If the holiday is in a different time zone from you, the day starts at a different moment — but the date is the date, and the countdown is in days, so the time zone does not change the number.
What is Yom Kippur?
Yom Kippur, the Day of Atonement, is the holiest day in Judaism, ten days after Rosh Hashanah. It is a day of fasting, prayer and repentance. Jewish holidays begin the evening before the date listed.
How Yom Kippur is observed
Jews fast for 25 hours, attend synagogue for most of the day and seek forgiveness. It is a public holiday in Israel, where even secular life pauses.
How the date is worked out
Yom Kippur is a moveable observance: its date changes from year to year. The table below gives the dates for 2026, 2027 and 2028, so you can see the pattern — and for planning more than a year ahead, use the days until calculator with the date for the year you need.

Yom Kippur 2027 in the calendar
Yom Kippur 2027 is the 284th day of 2027 — a year of 365 days — and it falls in ISO week 41 of the year. There are 81 days left in the year after it, and 31 days in October 2027. In the Northern Hemisphere it is autumn; in the Southern Hemisphere the seasons are reversed.
The week number matters more than people think: in business and government across Europe, dates are often given as week numbers, and the week number finder gives the ISO week for any date. The day-of-year number is used in astronomy, in logistics and in some payroll systems. And the days-left figure is the useful one for planning the rest of the year: after Yom Kippur 2027 there are 81 days — 11 weeks — left in 2027.
Planning for Yom Kippur 2027
334 days is 10 months — plenty of time to plan. If Yom Kippur means travel, book it now: fares and hotels are usually cheapest months in advance, and the popular dates sell out. If it means time off work, put the request in early, especially if the holiday falls on a weekday — Monday is a working day for most people, so the day off needs to be booked. And if it means gifts or preparations, the countdown is long enough that a little planning each week is worth more than a rush in the last few days.
Yom Kippur 2027 falls on a Monday — a weekday — so most people need to take the day off to mark it properly. Book the time off early, especially if the holiday is one people travel for: the days around a weekday holiday are among the busiest travel days of the year, and the fares rise as the date approaches.
The countdown in other units
The countdown to Yom Kippur 2027 is 334 days — which is 47 weeks and 5 days, 8016 hours, 480,960 minutes, or about 11.0 months. Of those 334 days, 238 are weekdays and 96 are weekend days — so if you are counting working days, there are 238 of them left before the holiday. The days between dates calculator works out the same numbers for any two dates, and the business days calculator counts the working days excluding public holidays.
Yom Kippur around the world
As a Jewish observance, this day follows the Hebrew calendar, and Jewish holidays begin the evening before the date listed. It is a public holiday in Israel, and in other countries it is observed by Jewish communities — with time off work depending on the employer and the country. The Hebrew calendar is lunisolar, so the Gregorian date moves from year to year.
