-H "Accept: application/json"This API does not send CORS headers, so a browser will block a direct call from your front end. Call it from your server, or put a small proxy in front of it.
This API is served over plain HTTP. Browsers block HTTP requests made from an HTTPS page, so you will need a server-side call.

Hebrew Calendar — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Hebrew Calendar free to use?
Hebrew Calendar is listed in our free catalogue and required no credential when we called it. It needs no authentication at all, so you can send a request without signing up. Free tiers can still carry rate limits or non-commercial terms, so check the provider's own terms before shipping.
Does Hebrew Calendar need an API key?
No. We called Hebrew Calendar on 2026-09-18 with no key, no token and no Authorization header, and it responded. That is what puts it in our no-key collection.
Can I call Hebrew Calendar from browser JavaScript?
Not directly. Hebrew Calendar did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is Hebrew Calendar still working?
Yes, as of 2026-09-18. Our automated check reached Hebrew Calendar and recorded a 100% reliability score with a median response time of 1500 ms. We re-check on a schedule, and this page updates with the result.
Is Hebrew Calendar available over HTTPS?
No. Hebrew Calendar was only reachable over plain HTTP when we checked. Browsers block HTTP requests made from an HTTPS page, so this will fail in production unless you call it from a server instead.
