UTC offsets are the arithmetic of global time: how many hours and minutes a place sits away from Coordinated Universal Time. This table lists all 38 offsets currently in civil use, from โ12:00 at Baker Island to +14:00 on Kiribati's Line Islands, each with its nautical letter and representative places - the full map from where the day ends to where it starts.
The edges of the table hold the surprises. Offsets stretch to +14:00, not +12:00, because the international date line bends east around Kiribati so its far islands share a working day with Asia. And offsets are not confined to whole hours: India sits at +05:30, Nepal at +05:45, and the Chatham Islands at +12:45 - a legacy of local mean time that survived standardization.
How to use
- Type an offset, place or nautical letter to filter - '+05:45', 'Nepal', 'Z' and 'Chatham' all find their rows.
- Click any offset to copy it, ready for meeting invites, log timestamps and config files.
- Remember DST: places that observe daylight saving sit one offset lower in their summer - the table shows each place at its standard time.
Frequently asked questions
What is the difference between an offset and a time zone?
An offset is just arithmetic - +05:30 means five and a half hours ahead of UTC. A time zone is a region with rules: India is one zone at +05:30 with no daylight saving; many zones share the same offset but differ in when, or whether, they shift. That is why scheduling software stores zone names (Asia/Kolkata), not offsets - the offset of America/New_York changes twice a year, the zone does not.
Why do some offsets end in :30 or :45?
Before standard time, every town kept its own solar mean time; when zones were standardized, some places refused to round more than necessary. Newfoundland kept โ3:30, India consolidated on +05:30, and Nepal took +05:45 to split the difference between Indian and Chinese time. Chatham's +12:45 and the Marquesas' โ09:30 are the same story at the edges of the map.
Which offset is first into a new day?
+14:00 - Kiribati's Line Islands - sees each calendar date about 26 hours before โ12:00 places like Baker Island do. For about two hours each day, three different calendar dates exist on Earth simultaneously; the +14/โ12 pair is why 'where does the day start' has a political answer, not a geometric one.
What is the nautical letter next to each offset?
The merchant-marine time tradition divides the globe into 25 letters (minus J): Z for zero (the origin of 'zulu time'), then A through M eastward and N through Y westward. Aviation and the military still speak in these letters - '1200 zulu' is noon UTC - and the letters survive in the table because log files and radio chatter still carry them.
