The mechanism
How the Hebrew calendar works
The Hebrew calendar is lunisolar: months follow the moon (29 or 30 days) while leap months keep the year aligned with the seasons. Seven of every nineteen years add a second month of Adar.
Twelve lunar months come to about 354 days against a civil year of 365, so without the leap month the festivals would drift backwards through the seasons by roughly eleven days a year and Passover would land in winter within a decade.
The day
A day that starts at sundown
A Hebrew day begins at sundown, so a Hebrew date covers the evening before the civil date shown through nightfall of that day. For a birthday after sunset, use the next Hebrew day.
It is the same rule behind every holiday on this site starting the evening before the date in the table, and behind Shabbat beginning on Friday afternoon. If you were born at 9pm, your Hebrew birthday belongs to the following day.
The moon on the night they were born, with the Hebrew date, framed.
Because the Hebrew months follow the moon, the moon on every Hebrew birthday comes back to nearly the shape it had on the night of the birth. The print shows that night and each birthday after it.

This year
The 13 months of 5787
The year runs from September 12, 2026 to October 1, 2027: it opens with Tishrei at Rosh Hashanah and closes with Elul, 385 days in all. Cheshvan and Kislev gain or lose a day to keep the festivals off the wrong weekdays, which is why a Hebrew year can be 353, 354 or 355 days long, and 383, 384 or 385 in a leap year.

Frequently asked questions
What Hebrew year is it now?+
The current Hebrew year is shown at the top of this page. Hebrew years run from Rosh Hashanah (September or early October) and are numbered from the traditional date of creation.
How do I find my Hebrew birthday?+
Enter your Gregorian birth date in the converter. If you were born after sunset, use the next day, since the Hebrew day begins at nightfall. Your Hebrew birthday recurs on that Hebrew date every year.
What is a yahrzeit date?+
A yahrzeit is the Hebrew-calendar anniversary of a death, observed with memorial customs. Convert the Gregorian date of passing (adjusting for after-sunset timing) to get the Hebrew date to track each year.
Why is there sometimes a second Adar?+
Seven times in every nineteen years the Hebrew calendar adds a leap month, Adar I, to stay aligned with the seasons. In leap years Purim and Adar dates fall in Adar II.
