World Time Zone Map
An interactive map of every time zone on Earth, colored by UTC offset, with the live local time in each. Tap a zone — or search any city or country — to see its current time, UTC offset, and whether daylight saving is in effect right now.
Zones are colored by their standard UTC offset. A few use half- or quarter-hour offsets (India UTC+5:30, Nepal UTC+5:45, Chatham Islands UTC+12:45). Time zone boundaries © OpenStreetMap contributors, via timezone-boundary-builder (evansiroky), ODbL v1.0. Boundaries are OSM-approximate, not a legal survey.
The world is commonly divided into 24 main time zones, one for each hour of longitude, but in practice there are about 38 distinct UTC offsets in use — from UTC−12 to UTC+14. The extras come from regions that use half- or quarter-hour offsets (India, Nepal, parts of Australia) and Pacific islands near the date line that run furthest ahead. Every zone is defined as an offset from UTC, the global time standard.

Offsets shown are standard time; many of these regions shift one hour for daylight saving in their summer. Tap a zone on the map for the live current offset.
UTC, GMT & time zones explained
What is UTC?
UTC (Coordinated Universal Time)is the world’s time standard — the single reference every time zone is measured against. It is kept by atomic clocks, is the same everywhere on Earth, and never changes for daylight saving. A place’s local time is just UTC plus or minus its offset: New York is UTC−5, Tokyo is UTC+9.
GMT vs UTC
GMT (Greenwich Mean Time)is the older standard — mean solar time at the Greenwich meridian (0° longitude) in London, which served as the world’s reference for over a century. UTC formally replaced it in 1972. For everyday purposes the two are identical (they never differ by more than a fraction of a second); “GMT” now mostly survives as a casual synonym and as the name of the UTC+0 zone in the UK and West Africa.
How offsets work
Each 15° of longitude corresponds to about one hour of offset — places east of Greenwich are ahead of UTC (positive), places west are behind it (negative). In reality the boundaries bend around national and provincial borders rather than following the meridians exactly, which is why the zone map is full of jogs and steps.
The international date line
Roughly opposite Greenwich, near the 180° meridian, runs the international date line — cross it westward and the calendar jumps forward a day; eastward, back a day. It zigzags to keep each country on one date: Kiribati bent it far east in 1995 (creating the UTC+14 zone), and Samoa skipped December 30, 2011 to move to the western side for trade with Australia and New Zealand.
Why some zones are :30 or :45
Not every offset is a whole hour. To better match solar time — or for political reasons — a dozen or so places use half- or quarter-hour offsets: India at UTC+5:30 (one national zone splitting its width), Nepal at UTC+5:45 (deliberately 15 minutes ahead of India), Newfoundland at UTC−3:30, and the Chatham Islands at UTC+12:45.
Notable time zone facts
- Most time zones: France. Its overseas departments and territories span 12 zones — from French Polynesia (UTC−10) to the Indian Ocean and Pacific — more than any other country. The United States and Russia are next with 11 each.
- Most contiguous zones: Russia. Across one connected landmass Russia covers 11 zones, from UTC+2 (Kaliningrad) to UTC+12 (Kamchatka).
- One zone despite huge width: China.China officially runs on a single zone (UTC+8, “Beijing time”) even though it geographically spans about five — so in far-western Xinjiang the sun can rise around 10 AM by the clock. India (UTC+5:30) likewise uses one national zone.
- The 26-hour spread.When it is noon on the Line Islands (UTC+14) it is 10 AM the previous day on Baker Island (UTC−12) — the same instant, 26 hours apart on the clock and calendar.
- Neighbours a day apart.The Diomede Islands sit 2.4 miles apart in the Bering Strait, but Little Diomede (US) and Big Diomede (Russia) are about 21 hours apart on the clock — often called “Tomorrow Island” and “Yesterday Isle.”
- Most of the world skips DST. Daylight saving is mainly a North American, European, and southern-hemisphere-Oceania practice; most of Asia, Africa, and the tropics keep the same offset all year.
