About this tool

See what time it is in any of 40+ timezones, convert a specific moment across zones, and translate Unix timestamps to human-readable dates and back. Ideal for remote teams and developers.

How it works

Timezone conversion uses the ECMAScript Intl.DateTimeFormat API with timeZone names, which correctly applies historical and seasonal UTC offsets. Unix conversion uses Date arithmetic against the UTC epoch, auto-detecting seconds versus milliseconds by digit count.

How to use Time Converter

1Choose "Timezones" to compare the same moment across locations, or "Unix time" to convert timestamps.
2In timezone mode, set a time or use "now", then every zone shows the matching local time.
3In Unix mode, paste a timestamp to read the human date, or pick a date to get its timestamp.
4Click any result row to copy it.

Examples

09:00 UTC is 17:00 in Singapore and 05:00 in New York (EDT).

The Unix timestamp 1784300000 reads as Wednesday, 17 July 2026, 08:53:20 UTC.

1 January 2026 00:00 UTC equals Unix timestamp 1767225600.

Pro tips

Timezone conversions respect daylight saving rules automatically.
Use "now" mode when scheduling meetings across timezones.
Developers: the tool accepts both seconds (10 digits) and milliseconds (13 digits) timestamps.

Frequently asked questions

What is a Unix timestamp?

The number of seconds elapsed since 1 January 1970 00:00:00 UTC. It is timezone-independent and used by nearly all operating systems and databases.

Does it handle daylight saving time?

Yes. The tool uses the browser Intl API, which applies each region's DST rules for the chosen date.

Can I convert between two specific timezones?

Yes — set your source timezone and target, then read the local time in both. The "now" shortcut fills both instantly.
