World time zone map

Every major city on the map, grouped by the UTC offset it is on right now. Pick an offset to see who shares it; hover a city for its local time.

The shaded side of the map is in night right now. Hover or tap a dot for its local time.

How to use the world time zone map

  1. Find your own offset

    The map opens with your UTC offset selected, so the highlighted dots are the cities that read the same clock as you right now.

  2. Pick another offset

    Choose any offset above the map to light up every city on it. The list under the map names them, with the current local time.

  3. Point at a city

    Hover or tap a dot for its local time, offset and weekday; open it for the full city page with clock changes and sun times.

Why time zones don't follow the lines you'd expect

In theory the world splits into 24 zones of 15 degrees each, one hour apart. In practice a time zone is a political decision, so the boundaries follow countries and states rather than meridians. China spans about 60 degrees of longitude, enough for four or five zones, and uses one: in Kashgar the sun can rise after 9 am on the clock.

There are also more than 24 offsets. India runs on UTC+5:30, Nepal on UTC+5:45, and parts of Australia on UTC+9:30. Kiribati moved its eastern islands to UTC+14 in 1995 so the whole country shares a date, which is why the first place to see each new day is in the middle of the Pacific.

Offsets also move. Daylight saving shifts most of Europe and North America by an hour twice a year, on different dates, and governments change their rules outright — Morocco returned to GMT (UTC+0) on 20 September 2026 after eight years on UTC+1. This map is drawn from the IANA time zone database the site ships with (the same source operating systems use), so it reflects those changes even when a browser's own copy is out of date.

Each dot is a real city placed at its coordinates, coloured by the offset it is on at this moment. The shaded band is the night side of the planet, computed from the sun's position, so you can see at a glance which offsets are in working hours and which are asleep.

When it comes in handy

  • Scheduling a call.

    Select your offset, then your colleague's, and see how far apart you are before reaching for the meeting planner.

  • Checking a trip.

    Find whether your destination is on a half-hour offset or a different day before you land.

  • Teaching time zones.

    Show how political borders, not meridians, decide the clock — China's single zone and India's half hour make the point quickly.

Questions & answers

How many time zones are there?
There are about 38 different UTC offsets in use, not 24, because several countries use half-hour or quarter-hour offsets (India UTC+5:30, Nepal UTC+5:45) and the range runs from UTC−12 to UTC+14. The IANA database tracks over 400 named zones, because places that share an offset today may have had different rules in the past.
Why is the map coloured by offset and not by zone name?
Because the offset is what decides the clock. New York and Toronto have different zone names but read the same time, so they are drawn together.
What time zone is Morocco in now?
Morocco uses GMT (UTC+0) all year since 20 September 2026, when it ended eight years on UTC+1. The map uses current IANA rules, so it shows Morocco on UTC+0 even if your browser's own time zone data predates the change.
