World time zone map
Spin the globe or switch to the flat map and point at any zone to see what time it is there right now, how far it is from UTC and from you, and which countries keep that clock.
Your time
Hours from UTC
Point at a zone, or tap it on a phone, to see its time now. Cool colours are behind UTC, warm colours ahead. Times come from your device's clock and include summer time.
World clock
The time now in big cities, from west to east. Each step east is later in the day, until the date line.

How time zones work, in five ideas
1 of 5
One hour is 15°
The Earth turns a full 360° every 24 hours, so the Sun moves 15° of longitude an hour. In theory that gives 24 neat zones, each 15° wide, counted from Greenwich in London.
Try it: Out at sea, the zones still follow those straight 15° strips.

Borders bend the lines
On land, governments pick their clock, and they usually follow country or state borders. China is wide enough for five tidy zones but officially keeps one clock, UTC+8; in Xinjiang, far west, many people live by a local clock two hours behind, which is what this map shows there. Spain sits beside Portugal and the UK but keeps Berlin's time.
Try it: Point at China, then at Spain and Portugal.

Not always whole hours
Most clocks are whole hours from UTC, but India is UTC+5:30, Nepal UTC+5:45, Iran UTC+3:30 and Newfoundland in Canada UTC−3:30. Parts of Australia and the Pacific are out by 30 or 45 minutes too.
Try it: Find Nepal: 15 minutes ahead of its neighbour India.

Summer time moves clocks
Many countries put their clocks forward an hour in summer. North America and Europe do it in their summer, Australia, New Zealand and Chile in theirs, so the gaps between them change twice a year. Most of Africa and Asia never do.
Try it: Point at a zone: the card says if it is on summer time now.

The date line
Go far enough east and you reach places that are already tomorrow. The International Date Line, roughly along 180°, is where the date changes. Kiribati's Line Islands are UTC+14, the first clocks to reach a new day.
Try it: Turn the globe to the Pacific and compare the dates either side.
Test yourself
Take the four-minute lesson with questions, then play Time Zone Hop: guess how many zones lie between two places.
Questions
How many time zones are there?
The tidy theory has 24, one per hour. In real life more than 35 different UTC offsets are in use, because of half-hour and 45-minute zones and the zones beyond ±12 hours near the date line. This map shows each distinct clock in use today.
What is UTC?
Coordinated Universal Time, the reference every time zone is counted from. For everyday purposes it is the same as Greenwich Mean Time (GMT), the time in London in winter.
Why does China have only one time zone?
Since 1949 the whole country has kept Beijing time, UTC+8, although it is wide enough for five zones. In the far west, the winter sun rises after 9:30 am by the clock.
Which country has the most time zones?
France, with 12, counting its overseas territories in the Atlantic, Indian and Pacific Oceans. Russia, the largest country, uses 11.
Are the times on this map right where I am?
The times are read from your own device's clock and its built-in time zone rules, so they include summer time and change on the right dates. The zone shapes are simplified for a world map, so close to a zone border check a local source.
