What is a time zone?

A time zone is a region that observes a uniform standard time for legal, commercial and social purposes. Time zones are defined by their offset from Coordinated Universal Time (UTC) and can be adjusted for Daylight Saving Time depending on the season.

How to use this converter

Your local time is shown at the top. Add or remove cities from the list to compare their current time against yours, and each city shows how many hours it is ahead of or behind you.

Frequently asked questions

How many time zones are there?

There are 24 standard time zones, one for each hour of the day, though some countries use half-hour or quarter-hour offsets, giving 38 distinct zones in practice.

Why do some cities show a different time than expected?

Daylight Saving Time (DST) shifts the local clock forward or back, so the offset shown can change with the season.

Is this timezone converter live?

Yes — times update every second and offsets account for the current DST rules of each city.
