Browse the whole directoryThe Hebrew calendar
What day is it, in the oldest calendar still in daily use?
Jewish festivals seem to move every year against the Gregorian calendar. They do not: they are fixed in a different calendar, one that follows both the moon and the sun.
Gregorian date
—
Hebrew date
—
Why it differs, and how
- The months follow the moon. A lunar month lasts about 29½ days, so Hebrew months alternate between 29 and 30 days, and each one begins near the new moon.
- But the year has to follow the sun, because the festivals are tied to the seasons — Passover must fall in spring, Sukkot at the autumn harvest.
- Twelve lunar months make roughly 354 days, eleven short of the solar year. Left uncorrected, Passover would drift backwards through the seasons, as festivals do in a purely lunar calendar.
More on the mechanics
- The fix is a thirteenth month, Adar I, inserted seven times in every nineteen years — the Metonic cycle. Those are the leap years, which is why in some years Purim falls in Adar II.
- A Hebrew day begins at sunset, not at midnight. A festival therefore starts the evening before the civil date shown here.
- Years are counted from the traditional date of creation, which is why the current year is in the 5000s while the Gregorian year is in the 2000s.
Upcoming festivals
Each festival begins at sunset on the evening before the date shown.
