About this tool
Compare the current time in several places on one screen. Add major cities or any time zone supported by your browser, then keep the board open while you work with people in other countries.
The clock uses named IANA time zones rather than fixed UTC offsets. That distinction matters because Warsaw, New York and Sydney change offset during the year, and they do not all change on the same date. The displayed time therefore follows daylight-saving rules automatically.
Everything is calculated on your device from its current clock and time-zone database. No location permission, account or server request is needed.

Questions people actually ask
- Does the clock handle daylight saving time?
- Yes. It uses named IANA time zones, so the offset changes on the date defined for that place instead of staying fixed all year.
- Why can two cities with the same time differ later in the year?
- Daylight-saving rules are set locally. Countries start and end them on different dates, and many do not use them at all, so an apparent match can be temporary.
