Every Time Zone, Live

Search all IANA time zones and see the current time and UTC offset in each.

This is a live directory of the world's time zones as your browser knows them — several hundred IANA identifiers, each with its current local time and UTC offset. Type a city, a region or an offset to narrow the list. Unlike a fixed table, this reads your browser's time-zone database, so daylight saving is already accounted for in every row.

Why zones are named Region/City

IANA identifiers such as Europe/Lisbon or America/Argentina/Buenos_Aires name a place rather than an offset, because offsets change and places do not. A zone identifier carries the whole history of that location's clock, including every daylight saving rule and political change. That is why software should store a zone id rather than a bare offset — see time zones for developers.

Offsets are not zones

Several zones can share an offset while following completely different rules. Two places at UTC+01:00 in January may be an hour apart in July. To compare specific places use the time zone converter; to see the whole spread at once use the UTC offset table.

Frequently asked questions

How many time zones are in this list?
Several hundred — the full IANA set your browser ships with, which is far more than the 24 people expect, because zones follow political borders rather than lines of longitude.
Does the list handle daylight saving?
Yes. Every time shown comes from your browser's current time-zone data, so zones observing daylight saving already show the shifted time.
Can I search by offset?
Yes — type an offset such as +05:30 and the list filters to zones currently at that offset.
