Visit timezone.io →Docs Pricing

timezone.io provides current time, UTC offsets, and daylight saving data for IANA time zones via a JSON API (https://api.timezone.io/v1) covering time zones, abbreviations, countries, cities, time conversion, and lat/long lookup. It also hosts worldtime.timezone.io, a free, keyless drop-in replacement for the shut-down worldtimeapi.org, serving the same paths and 15 response fields over HTTP or HTTPS. The site includes reference pages for zones, countries, cities, UTC offsets, and a time converter, plus free team boards for comparing local times across time zones.
