How this service works
Convert a Gregorian date to the Hebrew calendar (or back) with leap year, year type and major holiday dates.
Output
Returns a structured object containing the Hebrew date (day, month number, month name, year), whether the year is a leap year, the year type (e.g. deficient/regular/complete), year length in days, month length in days, the Gregorian date of Rosh Hashanah for that year, month number from Tishrei, a list of major holidays in the Hebrew year (each with name, Gregorian date, and Hebrew date), the corresponding Gregorian date, and the weekday.
Example use cases
Jewish holiday planning for an event
“I'm planning a Jewish wedding for September 10, 2026 — can you tell me the Hebrew date, whether that year is a Hebrew leap year, and list the major Jewish holidays falling in that Hebrew year?”
Hebrew date lookup for a yahrzeit
“My grandfather passed on the 5th of Cheshvan, 5782 in the Hebrew calendar — what was that date in the regular Gregorian calendar?”
Displaying Hebrew date in an app
“What's today's Hebrew calendar date for October 3, 2024? Include the month name, day, year, and the Hebrew year type so I can display it correctly.”

Endpoint
GEThttps://calendar-systems.x402tookit.com/hebrew-calendar?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to convert between Gregorian and Hebrew calendar dates, determine Hebrew leap year status or year type, find the Gregorian equivalent of a Hebrew date, or retrieve the list of major Jewish holidays for a given Hebrew year. Prefer this over general calendar APIs when Hebrew-specific metadata (year type, month from Tishrei, Rosh Hashanah anchor) is required.
Side effects
- Invalid date format (not YYYY-MM-DD) returns an error
- Date out of supported range returns an error or degraded result
- Invalid 'from' enum value returns an error
- Missing required 'date' query parameter returns an error
- A Hebrew date that doesn't exist (e.g. day 30 in a 29-day month) may return an error or degraded result
