How to use the Hebrew date converter
Pick a date in the Gregorian date field and the converter shows the Hebrew date, in Hebrew letters and in English, with the day of the week. It also works the other way: choose a Hebrew day, month and year, and the Gregorian date appears. If what you are converting happened after sunset, such as a birth or a passing in the evening, tick "After sunset". The Hebrew day begins at sunset, so the Hebrew date moves one day forward. Leap years, Adar I and Adar II, and months of 29 or 30 days all follow the same fixed Hebrew calendar that sets the Jewish holidays.
Today's Hebrew date and the sunset rule
A Hebrew day runs from sunset to sunset, not from midnight to midnight. That is why Shabbat begins on Friday evening, and why every Jewish holiday begins on the evening before its date. The box at the top shows today's Hebrew date twice: until sunset today, and from sunset this evening. Sunset depends on where you are and on the season, and the converter does not know your location, so it gives you both halves of the day instead of guessing a time.
How the Hebrew calendar works
The Hebrew calendar is lunisolar. Its months follow the moon and are 29 or 30 days long, while its years are kept in step with the sun, so Passover always falls in spring and Sukkot in autumn, by the seasons of the Land of Israel. An ordinary year has 12 months and 353 to 355 days. A leap year adds a thirteenth month: the year has Adar I and Adar II, and lasts 383 to 385 days. Seven years in every 19-year cycle are leap years, years 3, 6, 8, 11, 14, 17 and 19 of the cycle. The year number changes on Rosh Hashana, 1 Tishrei, which never falls on a Sunday, a Wednesday or a Friday.
The Hebrew months in order
From Rosh Hashana, the months are Tishrei (30 days), Cheshvan (29 or 30), Kislev (29 or 30), Tevet (29), Shvat (30), Adar (29), Nisan (30), Iyar (29), Sivan (30), Tammuz (29), Av (30) and Elul (29). In a leap year Adar is replaced by Adar I (30 days) and Adar II (29 days). Only Cheshvan and Kislev change length from year to year, and that is how the calendar keeps Rosh Hashana off the days it may not fall on. The Torah calls Nisan the first month (Exodus 12:2), while the year number changes in Tishrei.
Frequently asked questions
What is today's Hebrew date?
It is shown at the top of this page and updates by itself every day. Because the Hebrew day begins at sunset, the page gives two dates: the Hebrew date until sunset today, and the Hebrew date from sunset this evening.
How do I find my Hebrew birthday?
Enter your Gregorian date of birth. If you were born after sunset, tick "After sunset", because by then the Hebrew date had already moved to the next day. The result is your Hebrew birthday. To see when it falls in a given year, choose the same Hebrew day and month and that year in the Hebrew date fields, and the Gregorian date appears beside it. If you were born in Adar, note that a leap year has two months of Adar, and customs differ on which one to use.
Why does my Hebrew birthday fall on a different Gregorian date every year?
An ordinary Hebrew year is about 11 days shorter than a Gregorian year, until a leap month brings the two back together. So your Hebrew birthday moves within a range of about a month on the Gregorian calendar. Every 19 years the two calendars come back into step, and your Hebrew birthday usually falls on the same Gregorian date again, or one day away from it.
What Hebrew year is it now?
The Hebrew year 5787 began on Rosh Hashana, 1 Tishrei, which fell on 12 September 2026; the holiday begins at sunset the evening before. It is a leap year of 13 months and 385 days. The year 5788 begins on 2 October 2027. From Rosh Hashana until 31 December, the Hebrew year is the Gregorian year plus 3761. From 1 January until Rosh Hashana, it is the Gregorian year plus 3760.
What is a Hebrew leap year?
A year with 13 months instead of 12. The extra month gives the year two months of Adar, Adar I and Adar II, and keeps the holidays in their seasons. Seven of every 19 years are leap years. In a leap year, Purim is celebrated in Adar II.
When does the Hebrew day begin?
At sunset. A Hebrew date starts in the evening and lasts until the next sunset. So Shabbat begins on Friday evening, and a baby born on a Tuesday evening after sunset was born on Wednesday's Hebrew date. In the converter, tick "After sunset" for anything that happened after sunset.
How are a bar mitzvah, a bat mitzvah and a yahrzeit dated?
By the Hebrew date. Traditionally a boy becomes bar mitzvah at 13 and a girl bat mitzvah at 12, counted from the Hebrew date of birth, and a yahrzeit is kept every year on the Hebrew date of the passing. Start by finding the Hebrew date here. Dates in Adar, or on the 30th of Cheshvan or Kislev, can fall differently in later years, so in those cases ask a rabbi. For a yahrzeit, the Yahrzeit Calculator on this site lists the dates for the coming years.
