How time zone offset table works

The table answers one question for every zone at once: what is this place's offset from UTC right now? Each row shows the IANA zone name, the offset currently in force, the standard (non-DST) offset, whether daylight saving applies at that moment, and the zone's local wall-clock time at your chosen instant. The offsets are read from your device's own IANA time zone database — the same source every modern operating system uses — so they are exactly as current as your system's rules.

Daylight saving is detected by probing each zone in mid-January and mid-July. If the two probes differ, the zone observes DST sometime that year; comparing the current offset with the lower of the two says whether summer time is in force right now. Probing both seasons is what lets southern-hemisphere zones be correct: Sydney really is on summer time in January, when New York is not.

The zone list deliberately includes the cases people trip over: the half-hour zones (India at UTC+05:30) and quarter-hour zones (Nepal at UTC+05:45, Chatham at UTC+12:45/13:45), the giants that abolished DST (China, India, Phoenix), the hemispheres that run DST in opposite halves of the year, and the extremes from Midway at UTC−11:00 to Kiritimati at UTC+14:00 — the first place on Earth to see each new day.

Frequently asked questions

What is the difference between a UTC offset and a time zone?
An offset is just a number of hours and minutes from UTC, like UTC+05:30. A time zone is a region with rules: its standard offset, its DST schedule, and its history of changes. Many zones share an offset; the IANA names (Asia/Kolkata, not "IST") are unambiguous precisely because abbreviations like IST mean different things in different countries.
Why are some offsets not whole hours?
Some places set their clocks to their true solar noon rather than to a round offset. India uses UTC+05:30, Nepal UTC+05:45, and the Chatham Islands UTC+12:45 (13:45 in summer). Oddities like these survive because changing them would disrupt a country's whole schedule for no practical gain.
How does the tool know when DST is active?
It probes each zone's offset in mid-January and mid-July of the year in question. A zone whose two probes differ observes DST, and the season actually in force is found by comparing the current offset with the lower (standard) one. This works for both hemispheres and for zones with no DST at all.
Why does the list stop at UTC+14 and start at UTC−11?
The Earth's inhabited offsets run from UTC−11 (Midway) up to UTC+14 — Kiritimati in Kiribati, which moved to the far side of the date line in 1995 so the whole country shares one date. UTC+14 is the legal maximum: any higher would put a whole calendar day between a place and its trading partners.
Is every world zone in the table?
No — the IANA database carries hundreds of zones, many of them historical. The table curates about 55 zones that cover every inhabited continent, every inhabited offset, and the instructive odd cases. Use the filter box to find a zone quickly, or the time zone converter for any zone by name.
