IANA zones · the technical identifiers
The zone that resolve to AZOT.
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 AZOT, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Why are the Azores one hour behind mainland Portugal?
- Historically and geographically, the Azores sit much farther west into the Atlantic—about 1,500 km from Lisbon—so a UTC-01:00 standard offset better matches their solar time.
- Do the Azores follow the same daylight saving schedule as continental Portugal?
- Yes: they spring forward on the last Sunday of March and fall back on the last Sunday of October, staying in sync with Lisbon even though their baseline offset is one hour different.
- What does overlapping UTC+00 mean for summer life in the Azores?
- From late March to late October the Azores are on UTC+00:00, the same as Reykjavík and Dakar year-round, but still one hour behind London and Lisbon, which are on summer time then.
- Is Azores Standard Time used anywhere outside the Azores archipelago?
- No—AZOT is exclusive to the Portuguese Azores. It is the only time region in the world defined around this standard offset and DST pattern pair.
- When do the Azores change their clocks?
- The Azores spring forward to UTC+00:00 on the last Sunday in March and fall back to UTC-01:00 standard time on the last Sunday in October, on the same days as the rest of Portugal.
