Enter a time zone and a reference date/time to find its UTC offset — how many hours and minutes ahead or behind Coordinated Universal Time it sits. Select your time zone from the dropdown, pick a date (to account for daylight saving), and the tool returns the UTC offset, the current local time in that zone, and the time difference from UTC in a clear ±HH:MM format.

A UTC offset is the difference in hours (and sometimes minutes) between a given time zone and Coordinated Universal Time (UTC). For example, UTC+05:30 means the local time is 5 hours and 30 minutes ahead of UTC, while UTC-05:00 means the local time is 5 hours behind UTC.
UTC (Coordinated Universal Time) and GMT (Greenwich Mean Time) share the same current time and are often used interchangeably in everyday contexts. However, GMT is technically a time zone used by certain countries in Africa and Western Europe, whereas UTC is a time standard based on atomic clocks and Earth's rotation. UTC is the modern international standard.
Most time zones differ from UTC by whole hours, but some countries chose offsets based on their geographic or political preferences rather than strict 15-degree longitude divisions. For example, India uses UTC+05:30, Nepal uses UTC+05:45, and Iran uses UTC+03:30. These fractional offsets were adopted to better align with local solar time or to unify large regions under one time.
No. UTC is a fixed time standard and never changes for daylight saving time (DST). Only local time zones shift relative to UTC when DST is applied. For example, the US Eastern time zone is UTC-05:00 in winter (EST) and UTC-04:00 in summer (EDT). UTC remains constant year-round.
To convert a local time to UTC, subtract the UTC offset from the local time. If your local time is 14:00 and your offset is UTC+03:00, the UTC time is 14:00 − 3:00 = 11:00 UTC. Conversely, to find local time from UTC, add the offset to the UTC time.
The largest positive UTC offset is UTC+14:00, observed in the Line Islands of Kiribati (specifically Kiritimati / Christmas Island). The largest negative offset is UTC-12:00, observed in parts of the Pacific such as Baker Island and Howland Island. This means there can be a 26-hour difference between the most extreme time zones.
Countries that observe daylight saving time shift their UTC offset by +1 hour during summer months. For example, the UK is UTC+00:00 in winter (GMT) but shifts to UTC+01:00 in summer (BST). The specific start and end dates of DST vary by country. Always check the current date when working with time zones that observe DST.
Yes. Large countries that span multiple longitudes often have several time zones. The United States has six standard time zones (from UTC-05:00 to UTC-10:00), China spans five geographic time zones but officially uses one (UTC+08:00), and Russia uses eleven time zones ranging from UTC+02:00 to UTC+12:00.
