Time zones of the world

Each zone is shaded by its standard UTC offset, the clock it keeps outside daylight saving time. Choose one on the map to open its clock and next change, or search above for a city in its name.

Whole hours, shaded in turnHalf and quarter hours, such as India (UTC+5:30) and Nepal (UTC+5:45)

A time zone connects a region to its local clock rules. Its UTC offset can change with daylight saving time, so an offset alone is not a complete time-zone name. An IANA identifier, such as America/New_York, lets a calendar apply the rules for the date you choose.

Your device setting can differ from your physical zone. Use the time-zone finder, or choose a zone below to see its current clock and next change.
