Time zone converter
This converter shows what the clock reads in another time zone at one exact moment. You give it a date and time that includes Z or a UTC offset, and it shows the local time and offset in the zone you name. It helps people schedule calls across countries or read times in logs.

Example
2024-03-10T07:30:00Z
Local: 2024-03-10 03:30:00 GMT-04:00 Zone: America/New_York UTC: 2024-03-10T07:30:00.000Z
How to use the time zone converter
- Type a date and time with seconds and Z or an offset, such as 2024-03-10T07:30:00Z.
- Enter a zone in Destination time zone, such as America/New_York, using an IANA name.
- Press Run to see the local time, the zone and the UTC time.

How it works
The input must name an exact moment, so it needs Z or an offset like -05:00. Plain local times are rejected to avoid guesswork.
Zone names use the IANA format of Region/City, such as Asia/Tokyo or Europe/London.
Your browser's built in time zone data supplies the daylight saving rule for that date, so results depend on that data.
The result shows the local date and time with its UTC offset, the zone name and the UTC time.
Instants must fall in years 1900 to 9998, and leap seconds are not supported.
Everything runs in your browser. Your input is not uploaded or stored.
Questions and answers
What is an IANA time zone name?
It is a standard name such as America/Los_Angeles or Europe/Paris. It tracks a place's full history of offsets and daylight saving rules.
Does the converter handle daylight saving time?
Yes. For example, 2024-03-10T07:30:00Z in America/New_York shows 03:30 with a GMT-04:00 offset, because daylight saving had just started.
Why do I need to add Z or an offset?
A time like 09:00 means different moments in different places. Adding Z or an offset tells the tool exactly which moment you mean.
Why does a zone name give an error?
The name may be misspelled or not known to your browser. Check the Region/City spelling, such as Australia/Sydney.
