How do I find the right time zone?

Search by a city, country, or time-zone identifier, then open the matching clock. Filter by region to narrow the list. The directory includes geographic zones, fixed UTC offsets, and alternate names, so familiar older names can still lead you to a current entry.

A regional zone is not a fixed offset

New York and UTC−05:00 coincide in this January example but differ in July. For a future appointment, choose a regional identifier and the appointment date; a fixed offset cannot follow seasonal changes.

Names identify rules, not just a number

An IANA time-zone identifier usually combines a region and a representative city, such as Asia/Tokyo or America/New_York. The city stands for an area that follows those rules; it does not mean the zone is limited to that city. Large countries may contain several zones, so choose the place closest to the location you need.

Some names are historical aliases. Search recognizes the alternate names in the directory and opens the corresponding entry. The clock page shows the exact identifier being used, along with the date and current offset, so you can check that you chose the intended region.

Why a fixed offset is different

Fixed-offset zones keep the same relationship to UTC throughout the year. Geographic zones can change their offsets for daylight saving or other local rules. If you are coordinating a future appointment, a regional zone is usually more useful than assuming that today’s offset stays the same.

The legacy Etc/GMT identifiers use a reversed sign convention: Etc/GMT+5 represents UTC−05:00. Read the current UTC offset on the clock page rather than interpreting the identifier’s sign as an ordinary arithmetic offset. UTC itself does not change for daylight saving.

Choosing a clock for a country

Country search can return multiple entries. The United States, Canada, Australia, and several other countries span more than one zone, and nearby locations may follow different seasonal rules. Check the city name and identifier rather than choosing the first country match automatically.

The directory is a reference to time-zone names, not a complete gazetteer of every town. If your town is absent, choose a representative city that uses the same regional rules. Abbreviations alone can be ambiguous across countries; a full identifier gives a clearer match.

Keep regional rules current

The directory is built from the public IANA Time Zone Database. The live clock uses the rules shipped with your browser. Governments can change those rules, and an older browser may not include a recent update. Update your browser and confirm important future schedules with the event organizer.

Open a city page to view its live clock, full date, calendar details, and upcoming offset change. Save a few clocks to compare them, or use the Time Zone Calculator for a specific future date. The countdown timer and stopwatch measure durations and do not require a regional time-zone choice.
