FIST
Falkland Islands Standard Time
Falkland Islands Standard Time (FIST) keeps the archipelago on a single, year‑round UTC−03:00 clock, so scheduling with London or Buenos Aires means no mid‑year surprises—just a fixed three‑hour gap behind Coordinated Universal Time.

IANA zones · the technical identifiers
The zone that resolve to FIST.
For software, always store the IANA identifier — never the abbreviation alone. The database keeps these zones distinct because their rules can, and historically did, diverge.

Frequently asked questions
Common questions about FIST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Does the Falkland Islands ever switch to daylight saving time?
- No. The islands abolished daylight saving in 2010 and permanently standardized on UTC‑03:00 (FIST), so the clocks never move forward or backward.
- How does FIST compare to Argentina’s time zone?
- Buenos Aires usually sits on UTC‑03:00 as well, so the Falklands share the same local time for much of the year—though they don’t follow Argentina’s occasional one‑hour daylight shifts.
- What happens when the UK is on British Summer Time?
- While the UK springs forward to UTC+01:00 between March and October, the Falklands stay at UTC‑03:00, widening the gap to four hours instead of the usual five.
- Is there ever a clock‑change transition to watch for in Stanley?
- No. The most recent switch ended with the DST cancellation in 2010, and today’s timezone data shows no scheduled future transition—FIST is effectively fixed.
- Why do some flight schedules list the Falklands as UTC‑04:00?
- These listings pre‑date 2010 or stem from confusion with neighboring South American regions; since that year every official timetable uses UTC‑03:00.
- What’s the best hour in FIST to call colleagues in London?
- Mid‑morning to early afternoon in the Falklands (09:00–14:00 FIST) overlaps London’s active work hours, because the four‑hour summer difference and five‑hour winter difference are most stable then.
- How does a fixed UTC‑03:00 offset affect daily life in Stanley?
- Sunrise stays reliably between roughly 07:00 and 10:00 local time, giving residents predictable daylight without the seasonal clock‑shifts common on the South American mainland.
- Does Skype or Google Meet auto‑detect DST for the Falkland Islands?
- Fully updated calendar services treat Atlantic/Stanley as a no‑DST zone (UTC‑03:00), so calendar blocks won’t accidentally shift by an hour.
