How to convert a time zone
- Choose a date and time, or select Now.
- Choose the source time zone.
- See the converted time in up to three other time zones at once.
How daylight saving time is handled
This tool uses your browser's built-in time zone database (the same one used by your operating system) to determine the correct UTC offset for the exact date you choose, so daylight saving time transitions are handled automatically and correctly for each time zone.
Common use cases
- Schedule a meeting across multiple time zones
- Check what time it is somewhere else right now
- Convert a specific date and time to another time zone
Frequently asked questions
Is this tool free?
Yes. It is completely free, with no signup and no limits.
Is my data uploaded anywhere?
No. Conversion happens entirely in your browser.
Does this handle daylight saving time correctly?
Yes. It uses your browser's built-in time zone data, which already accounts for each region's daylight saving rules and change dates.
Can I convert to more than one time zone at once?
Yes. Three destination time zones are shown at once, so you can compare several locations for the same source time.
Why do some countries not observe daylight saving time?
Daylight saving time is a policy choice — many countries near the equator or with their own scheduling rules don't observe it, which this tool reflects automatically since it uses real time zone data.
