FAQ

Is Daylight Saving Time applied automatically?

Yes. The tool uses the browser's Intl API, so DST for each city is applied automatically.

Is the displayed time accurate?

It is based on your browser's system clock. As long as your device clock is accurate, the displayed times will be too.

What if the city I want is not on the list?

Refer to another city in the same timezone. For example, Bangkok and Jakarta are both UTC+7.
