This is a list of the UTC time offsets, showing the difference in hours and minutes from Coordinated Universal Time (UTC), from the westernmost (−12:00) to the easternmost (+14:00). It includes countries and regions that observe them during standard time or year-round.

The main purpose of this page is to list the current standard time offsets of different countries, territories and regions. Information on daylight saving time or historical changes in offsets can be found in the individual offset articles (e.g. UTC+01:00) or the country-specific time articles (e.g. Time in Russia).

Places that observe daylight saving time (DST) during their respective summer periods are listed only once, at the offset for their winter (usually known as "standard") period; see their individual articles for more information. A source for detailed DST and historical information is the tz database. Note that there are many instances of unofficial observation of a different offset (and/or DST) than expected by areas close to borders, usually for economic reasons.

In the section names, the letter after the offset is that used in nautical time, with which the UTC offset section overlaps at least partially. Nautical time strictly partitions the globe at 15 degrees, whereas UTC offsets can deviate, for instance according to borders. If present, a dagger (†) indicates the usage of a nautical time zone letter outside of the standard geographic definition of that time zone.

Some zones that are north/south of each other in the mid-Pacific differ by 24 hours in time – they have the same time of day but dates that are one day apart. The two extreme time zones on Earth (both in the mid-Pacific) differ by 26 hours.

In the following list, only the rightmost indent of a group of locations is meant to indicate the area observing the offset; the places above and to the left are meant solely to indicate the area's parent administrative divisions. For example, the entry of Eucla explains that Eucla observes the specified time offset, and the state (Western Australia) and country (Australia) are shown only for reference and are not meant to be wholly included as observing that offset.

The purpose of the "principal cities" list at the top of some of the time zone entries is to give a brief list of major cities. These should be limited to a maximum of one city per country (within each zone), and not all countries in a zone need to have a city listed. Similarly, time zones need not have any cities listed if there are no major cities in that offset.
