Free Time Zone Converter & Unix Timestamp Online

Get the current time in any timezone, convert between timezones and Unix timestamps (seconds or ms), with UTC offset and weekday for up to 30 zones.

Result

Press “Run” to see the result.

The Time API returns the current time – or any time you give it – in UTC, as Unix seconds and milliseconds, and as local time in up to 30 IANA timezones at once (timezones=UTC,Asia/Ho_Chi_Minh,America/New_York). Each zone comes with its UTC offset (DST aware) and weekday. Without a timezone, the caller’s timezone detected by Cloudflare is used, falling back to UTC.

time accepts an ISO 8601 date with an offset or Z, Unix seconds (10 digits) or milliseconds (13 digits), or a local date-time without offset such as 2026-11-10 09:00, which is interpreted in from_timezone (default UTC). That makes it a quick timezone converter: "09:00 in Hanoi is what time in New York?"

Unknown timezone names do not fail the request; that zone just returns an error field. Add list=true to get the full list of supported IANA timezone names.

FAQ

How do I convert a Unix timestamp to a date?

Call /v1/time?time=1794000000&timezones=Asia/Ho_Chi_Minh. 10-digit values are read as seconds, 13-digit values as milliseconds.

How do I convert a local time from one timezone to another?

Pass the local time without offset plus its zone: time=2026-11-10T09:00:00&from_timezone=Asia/Ho_Chi_Minh&timezones=America/New_York returns 2026-11-09T21:00:00-05:00.

Is daylight saving time handled?

Yes. Offsets come from the IANA timezone database for that exact date, so a zone like Europe/Paris returns +01:00 in winter and +02:00 in summer.
