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...
