      III. The long view

      Some years cost more than others.

      The Hebrew calendar drifts against the civil week, so the number of holidays landing on workdays swings year to year. Compare a span of years below.

      IV. A field guide

      About the holidays.

      What each observance is, when it falls this year, and whether work is traditionally permitted.

      V. For machines

      One API. Every HR calendar.

      Everything on this page is powered by a free, no-auth JSON API — computed locally from the Hebrew calendar, no rate-limited third parties. Pipe it into Workday, BambooHR, Google Calendar, or anything that speaks REST or iCal.

      • JSON endpoints for holidays, workday counts, multi-year comparisons
      • iCal (.ics) feed for Workday absence & Outlook/Google calendars
      • Diaspora or Israel schemes, configurable weekends (Fri–Sat supported)
      • OpenAPI 3.1 spec — generate a client in any language
