Time zone converter

Pick two cities and a local date and time. The converter applies the correct UTC offset for that exact moment, including daylight saving time.

How time zone conversion works

Each city follows a time zone from the IANA Time Zone Database, which records every historical and scheduled offset change. The time you enter is converted to Coordinated Universal Time (UTC) using the first city's offset at that moment, then shown with the second city's offset. Because daylight saving dates differ between countries, the difference between two cities can change during the year.
