What is UTC?
UTC is a shared time reference. It does not follow summer-time changes. UTC+08:00 means the local clock is eight hours ahead; UTC−05:00 means five hours behind.

UTC+00:00
Current time comes from your device clock. Local rules come from your browser’s time-zone data, which may be out of date.

50 curated major cities, not every town. Search also accepts Chinese names, common aliases and IANA zone IDs.
Live mode. All cities share one current instant.
The same moment around the world
Local times use IANA zones and Gregorian dates. 24-hour clock.
No city found. Try a country, English / Chinese name, or IANA zone ID. The catalog covers 50 cities.
Make sense of the time difference
The date can change, too
At UTC 20:30, Kathmandu (UTC+05:45) is already at 02:15 the next day. “Previous / same / next day” compares the city’s date with the UTC date shown above, not your device’s today.
Why offsets change
Some places change their clocks seasonally. The offset shown here belongs to the selected date, not today’s offset. The browser applies the IANA rules for that city; this tool does not guess whether daylight saving is active.
Missing and repeated local times
In New York, 2026-03-08 jumps from 01:59:59 to 03:00:00. On 2026-11-01, 01:30 happens twice: 05:30 UTC has offset −04:00; 06:30 UTC has offset −05:00. Entering UTC identifies one instant unambiguously. City-local input is not supported.
Accuracy and privacy
This is a planning aid, not an independently synchronized time service. Keep your device clock and browser current and verify critical appointments with the destination. Historical and future rules can change. Searches and conversions stay in this page; no location permission or account is needed. Nothing is saved.
