World Time Zone Map

How to use World Time Zone Map

The map above is interactive and live: every colored band is one zone, and the clocks inside it update in real time. Click a band or a city to pin it, then click a second one — the tool works as a converter, showing both local times side by side. The numbers along the top are UTC offsets: negative to the west of Greenwich, positive to the east. If you only remember one thing, remember that a place with a bigger offset is further into its day.

Colors mark zones, not countries, which is why one country can wear several stripes and why a stripe can bend around a state line. That bending is where most scheduling mistakes are born.

Time zone map in the United States

Across its states the country spans six zones, which is why a time zone map in the United States gets consulted more often than almost any other. From east to west: Eastern (UTC−5): New York, both Carolinas, most of Florida

Central (UTC−6): Chicago, Texas, most of the Midwest Mountain (UTC−7): Denver, most of Arizona — which skips daylight saving Pacific (UTC−8): California, Los Angeles, Seattle — the home of PST Alaska (UTC−9): almost the entire state

Hawaii–Aleutian (UTC−10): Hawaii, which never moves its clocks During daylight saving the mainland offsets shift one hour toward UTC; Hawaii and most of Arizona stay put. So Honolulu is two hours behind California in winter and three in summer — the same islands, a different gap.

An Indiana time zone map deserves its own glance: the state is mostly Eastern, but a handful of counties near Chicago and around Evansville keep Central time. If a meeting with someone in Indiana feels off by an hour, check the county before blaming anyone's calendar.

Europe, Asia and the Pacific

Europe is compact on the map: Western European time around the UK and Portugal, Central European time across most of the continent, Eastern European time from Finland down to Greece — three neighboring bands where the US needs six.

Japan runs on UTC+9 all year, with no daylight saving, so the distance between Tokyo and any American city changes twice a year even though Tokyo itself never moves. The Philippines sits at UTC+8, also year-round. Australia is the map's trick question: it spans three main zones, the central one offset by half an hour, and only some states observe summer time.

A meeting set for “9 o'clock” with no zone attached is actually two meetings, and somebody always shows up to the wrong one.

Reading the daylight line

The lit and dark halves of the map answer a different question from the clock. The clock says it is nine in the evening; the shading says whether the sun has actually gone down. Near the poles those two facts come apart dramatically — a summer midnight can be light, and a winter mid-morning can be dark.

The curve of the boundary between light and dark tilts through the year as the seasons change. It is flat around the equinoxes and most steeply tilted at the solstices, which is the same fact as the days being long in one hemisphere and short in the other.
