Timezone

Convert date and time between any two timezones instantly. Search from all IANA time zones. Free, no sign-up, all processing client-side in your browser.

A free online timezone converter that translates a date and time from one IANA time zone to another, instantly and entirely in your browser. Search across every IANA zone by name — America/New_York, Europe/Berlin, Asia/Tokyo, and the rest — and convert a specific moment between them without doing the offset math yourself. It is built for the everyday scheduling problems developers and remote teams hit: turning a meeting time into a colleague’s local zone, reading a UTC timestamp as a regional time, or checking what time it currently is in another city before booking a call. Because it runs client-side, no data is sent anywhere.

Common uses

  • Convert a meeting time from your local zone to a colleague’s zone.
  • Translate a UTC timestamp into a specific regional local time.
  • Check the current local time in another city before scheduling a call.
  • Plan a release or maintenance window across teams in different regions.
  • Work out the local start time of an event announced in another time zone.

Frequently asked questions

Which time zones are supported?

All IANA time zone identifiers (e.g. America/New_York, Europe/Berlin, Asia/Tokyo), searchable by name.

What input format does it expect?

An ISO 8601 date-time such as 2024-06-15T12:00:00, interpreted in the selected source time zone.

Does it account for daylight saving time?

Yes. IANA zones carry their DST rules, so a conversion reflects whether daylight saving was in effect at the date you enter.

What is the difference between a timezone converter and a Unix timestamp converter?

A timezone converter moves a calendar date-time between regions; a Unix timestamp converter turns an epoch number into a readable date. Use this tool for the former and the timestamp tool for the latter.

Is my data sent to a server?

No. All conversion runs in your browser, so the dates and zones you enter stay on your device.

All processing is local — your data never leaves your browser.
