What is the Hebrew Calendar?
The Hebrew calendar is lunisolar. Months follow the moon, and a leap month, Adar I, is added seven times in every nineteen years so that the holidays stay in their seasons. A year can have twelve or thirteen months, which makes the Hebrew date hard to work out by hand.
This tool shows today's Gregorian and Hebrew dates at the top. The Full Year tab draws all twelve Gregorian months with the Hebrew day number in each box, and marks Shabbat and the holidays. The Date Converter tab turns any Gregorian date into its Hebrew date and, when available, the weekly Torah portion. The Jewish Holidays tab lists the holidays for the year you are viewing.

Questions people ask
What is today's Hebrew date?
It is shown at the top of the page and is worked out when you open it. After sundown the Hebrew date is already the next day.
Why does the calendar have a leap month?
The Hebrew year follows the moon and the seasons. A leap month, Adar I, is added in seven of every nineteen years to keep holidays like Passover in the spring.
How many days are in a Hebrew year?
A year has 353, 354 or 355 days in a regular year and 383, 384 or 385 days in a leap year.
Which holidays does the Holidays tab show?
The main holidays and a few others, such as Rosh Hashanah, Yom Kippur, Sukkot, Hanukkah, Purim, Passover, Shavuot and Tisha B'Av. The Jewish Holidays tool lists many more.
Can I rely on this for a yahrzeit?
It gives you a starting point. Ask your rabbi, because customs for leap years and for the date of death differ.
