How time zone conversion works
Every time zone is an offset from UTC (Coordinated Universal Time), for example UTC-05:00 for New York in winter. Many countries move their clocks for daylight saving time, so the offset changes during the year and on different dates in different countries. This tool uses the zone rules built into your browser, so it picks the right offset for the exact date you choose.
Tips for scheduling across zones
Check the day shown beside each city. A late evening meeting in the US can already be tomorrow in Asia. For a precise machine time, see the epoch converter. For chat apps, create a time everyone sees in their own zone with the Discord timestamp generator.
Frequently asked questions
Does it handle daylight saving time?
Yes. The offset is calculated for the date you pick, so summer and winter times are both correct.
Which cities and zones are supported?
All time zones known to your browser (the IANA list), with the most common ones grouped at the top of the menu.
What does the day label mean?
It tells you if the converted time falls on the same day, or one day earlier or later than your starting time.
Is my data sent anywhere?
No. All conversions run in your browser. Your chosen zones are only remembered on your device.
