AST
Apia Standard Time
Apia Standard Time (AST) is the +13:00 zone used exclusively by Samoa in the South Pacific. It steers clear of daylight saving time, offering a consistent 13 hours ahead of UTC that makes it one of the earliest major time regions on Earth—while most of the planet says goodbye to the day, Apia is already deep into the next.

About AST
A fixed, year-round offset.
Apia Standard Time (AST) is the +13:00 zone used exclusively by Samoa in the South Pacific. It steers clear of daylight saving time, offering a consistent 13 hours ahead of UTC that makes it one of the earliest major time regions on Earth—while most of the planet says goodbye to the day, Apia is already deep into the next.
IANA zones · the technical identifiers

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 AST, daylight saving, and how to handle it in software. Can't find what you need? Email [email protected].
- Why is Apia Standard Time fixed at UTC+13:00 with no daylight saving?
- Samoa observed daylight saving time until April 2021 and then cancelled it, so it has stayed on UTC+13:00 all year since.
- What makes Apia Standard Time one of the ‘earliest’ time zones on Earth?
- At UTC+13:00, Samoa is among the first places to start each new calendar day; only Kiribati's Line Islands (UTC+14:00) are ahead all year. When it's midnight in Apia, it's 11:00 UTC on the previous day.
- Which countries and territories use Apia Standard Time?
- Only Samoa observes Apia Standard Time.
- Has Samoa ever used daylight saving time?
- Yes. Samoa observed daylight saving time from September 2010 to April 2021; after its 2011 date-line switch that meant UTC+14:00 in the southern summer. It dropped daylight saving in 2021 and has stayed on UTC+13:00 since.
- Does Samoa ever share the same clock time as its neighbors?
- Samoa shares UTC+13:00 with Tonga and Tokelau. Its closest neighbor, American Samoa, is on UTC-11:00, so the two show the same clock time but are a full calendar day apart.
- What’s a surprising fact about Samoa’s date line switch in 2011?
- Samoa skipped Friday, December 30, 2011, moving from UTC-10:00 to UTC+14:00 (its daylight saving time then) and so crossing to the other side of the International Date Line, which put its working week in line with Australia and New Zealand.
- How does Apia Standard Time affect daily life in Samoa?
- With sunrise and sunset times that barely change year-round thanks to the tropical location and no clock shifts, Apia Standard Time gives Samoans a predictable schedule for work, school, and evening activities like church and family time.
- Is there any upcoming change to Apia Standard Time scheduled?
- There are no known future transitions that would change Samoa’s +13:00 standard time or reintroduce daylight saving.
