Hebrew Calendar

API

Free API for Hebrew-Gregorian conversions & Jewish holiday/Shabbat times

Overview

The Hebrew Calendar API provides RESTful endpoints for converting dates between Gregorian and Hebrew calendars, retrieving Shabbat start/end times, and accessing detailed Jewish holiday info (biblical, historical, modern). Responses are JSON-formatted. Key endpoints include date conversion (/convert), Shabbat times (/shabbat), and holiday listings (/holidays). Ideal for integrating Jewish calendar features into scheduling apps, religious reminders, educational tools, or cultural platforms needing accurate Hebrew date calculations.
