World Time Zone Map
Current UTC offsets, daylight-saving status, and major city clocks across IANA time zones.
How to read this map
The land layer shows geography, city markers show exact locations, and the shaded bands are only UTC-offset references. Real time-zone borders are political and irregular, so the authoritative values on this page come from each city's IANA time zone.
The map layer uses IANA-based time-zone polygons colored by current UTC offset. City points use exact IANA time zones for local time and DST; the bottom strip is a UTC-offset legend.

World time zones, UTC offsets, and DST
Use this map as a practical overview of current offsets, then open a city page when you need an exact local clock, date, or daylight-saving rule.
UTC offsets are the quick comparison layer
The colored bands show the current offset from Coordinated Universal Time. They are useful for comparing regions at a glance, but they are not legal timezone borders.
IANA zones keep city clocks accurate
Each marker uses an IANA identifier such as Europe/London or America/New_York. That is what lets the clock account for local rules, historical changes, and daylight-saving transitions.
Daylight saving can change the answer
Two cities can share an offset today and separate later in the year. The DST label on each city shows whether it is currently observing daylight saving, standard time, or no DST.
Frequently Asked Questions
Each city is associated with an IANA time zone such as Asia/Tokyo or Europe/London. We render server-side using `Intl.DateTimeFormat` for that zone, then refresh on the client so the time stays accurate without round-trips.
Yes. The page detects whether each city is currently observing DST by comparing the January and July UTC offsets for its IANA zone, then labels each city as Observing DST, Standard time, or No DST.
Cities come from the WorldStats geography database (GeoNames-derived), filtered to capitals and large urban areas with a known IANA time zone, then ranked by population.
Two zones can share the same UTC offset right now and diverge later in the year. For example, Europe/London and Africa/Casablanca both sit on UTC+00 in winter, but only London moves to UTC+01 in summer.
