Hebcal

Connects Claude to Hebcal's Jewish calendar APIs, giving you programmatic access to holiday dates, Shabbat candle lighting times, Torah readings, and Hebrew date conversions. You can generate Jewish holidays for any year past or future, look up yahrzeits and anniversaries, and get both full kriyah and triennial Torah reading schedules. Runs over stdio by default or as an SSE server on HTTP. Reach for this when you're building apps that need accurate Jewish calendar calculations or when you want Claude to answer questions about Hebrew dates and observances without hardcoding holiday tables.
