Time Zone List & UTC Offsets

Browse and filter IANA time-zone identifiers, abbreviations, and UTC offsets for a selected date. Open any zone in the time converter.

Open tool

Time Zone Abbreviations

Understand common time-zone abbreviations and UTC offsets. Resolve ambiguous labels such as CST and IST, and choose a city for accurate conversions.

Open tool

Start with a place and a date.

A city’s time difference can change during the year. Our tools use the maintained IANA time-zone database on the server, including half-hour and quarter-hour offsets. Future dates follow the latest published rules; governments can still change them.

Which tool should I use?

I already know the event time.

Use the time zone converter for a quick comparison, or the event time announcer to create a shareable invitation and calendar file.

I need a time that works for a team.

The international meeting planner ranks possible starts by how many locations can fit the entire meeting inside their working hours. The working hours overlap tool shows common windows for handoffs and regular collaboration.

I’m planning a recurring meeting.

Check the time difference calculator’s year-long comparison and the daylight saving checker before booking a series. Calendar exports here create a single event; they do not create a recurring series.
