About World Clock & Time Zone Converter

Daylight Saving Time (DST) changes across North America, Europe, and Australia are calculated automatically using the modern browser Intl API.

A convenient 🌙 badge indicates night hours (10:00 PM – 6:00 AM) so you can avoid calling contacts while they are sleeping.
