# timezone.io > timezone.io tells you the time anywhere and explains the time zones behind it: the current time, UTC offset and daylight saving schedule for every IANA time zone, country and major city, with a time zone converter, team boards for people spread across time zones, and a free JSON API. Offsets and daylight saving rules come from the IANA tz database (release 2026d). The API computes offsets and daylight saving state for the moment of each request, so answers are right on the day the clocks change. Pages use the names people use (Eastern Time, CET, "Tokyo time"); IANA identifiers such as America/New_York have their own reference pages. Pages are HTML. The docs and legal pages also answer requests sent with `Accept: text/markdown` with their markdown source, and each docs page has a plain-markdown copy at its address plus `.md`, linked below. ## Website - [Time zones](https://www.timezone.io/zones): The named time zones, like Eastern Standard Time, Central European Time and Japan Standard Time, with their live time. Each has a page at /zones/{name}, for example https://www.timezone.io/zones/eastern-standard-time. - [Countries](https://www.timezone.io/countries): Every country and territory by continent, with its time zones and daylight saving rules. Each has a page at /countries/{name}, for example https://www.timezone.io/countries/france. - [Cities](https://www.timezone.io/cities): Major cities with their local time, time zone, sunrise and sunset. Each has a page at /cities/{name}, for example https://www.timezone.io/cities/tokyo. - [UTC offsets](https://www.timezone.io/offsets): Time zones grouped by their offset from UTC. Each offset has a page, for example https://www.timezone.io/offsets/utc+5. - [IANA time zones](https://www.timezone.io/iana/America/New_York): A reference page for each IANA identifier at /iana/{identifier}, with its rules and upcoming transitions. - [Converter](https://www.timezone.io/convert): Convert a time between two places or time zones. Pairs have their own pages at /convert/{from}-to-{to}, for example https://www.timezone.io/convert/new-york-to-london. - [Upcoming daylight saving changes](https://www.timezone.io/dst/upcoming): The next clock changes worldwide, soonest first. - [Daylight saving by zone](https://www.timezone.io/dst/zones): Every time zone that observes daylight saving, and whether it is on it now. - [Team boards](https://www.timezone.io/team): Share a link with your team and see everyone's local time on a live board grouped by time zone, with their working hours and the best times to meet. ## API The API returns JSON and requires a free personal access token from a verified account.
