Frequently asked questions

Does this need a third-party timezone database?

No — it's built entirely on Node's built-in Intl.DateTimeFormat and the IANA timezone database, so there's no upstream dependency to fail.

Can I find overlapping work hours for two teams?

Yes — /business-hours-overlap takes two timezones and working-hour ranges and returns the overlap window.

Is there a free tier?

Yes — 500 calls/month forever, no credit card.
