Time Zone Converter
Convert a date and time from one time zone to another. Daylight saving is handled automatically through your browser's own time zone database.
How to use the Time Zone Converter
Pick the date and time you want to convert.
Choose the from and to time zones.
Read the converted local time and the offset difference between the two zones.
Frequently asked questions
How does the conversion work?
The time you type is read as the local wall-clock time in the “from” zone. The tool finds the matching instant in time and then displays it in the “to” zone using the browser's built-in time zone database.
Does it handle daylight saving time?
Yes. Because it uses the IANA time zone database through Intl, daylight saving transitions on the chosen date are applied automatically.
Which time zones are available?
All zones your browser exposes through Intl.supportedValuesOf, with a short fallback list on older browsers. UTC is always included.
