AST
Apia Standard Time
Apia Standard Time (AST) at UTC+13:00 is the heartbeat of Samoa, a single‑zone region with no daylight saving—so the clocks stay predictably fast year‑round. For remote teams, coordinating with Apia means realizing that when you’re just starting your Monday, it’s already Tuesday lunchtime in the Pacific.

About AST
A fixed, year-round offset.
Apia Standard Time (AST) at UTC+13:00 is the heartbeat of Samoa, a single‑zone region with no daylight saving—so the clocks stay predictably fast year‑round. For remote teams, coordinating with Apia means realizing that when you’re just starting your Monday, it’s already Tuesday lunchtime in the Pacific.
IANA zones · the technical identifiers
The zone that resolve to AST.
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 doesn’t Samoa use daylight saving time?
- Samoa sits so close to the equator that daylight length barely changes throughout the year, making DST to save daylight both unnecessary and confusing for locals and traders.
- How does AST compare to popular business hubs?
- At UTC+13, Apia is three hours ahead of Auckland and five hours ahead of Tokyo, so European offices can usually start a full workday before most Samoan businesses even open.
- Family across other Pacific islands?
- Even though Fiji and Tonga also sit near the International Date Line, they use different offsets (UTC+12 or +12/+13 with DST), so a simple phone call can jump you a full calendar day.
- Samoa’s quirky time‑zone history?
- In 2011 Samoa jumped from UTC−11 to UTC+13, skipping an entire day (Friday, 30 December 2011) to align clocks with major trading partners Australia and New Zealand.
- Does any nearby territory share AST?
- AST is unique—only Samoa’s Pacific/Apia keeps that exact UTC+13 offset without DST, so anyone saying “I’m on +13” is almost certainly in Samoan time.
- What’s a practical tip for scheduling with Apia?
- If you’re booking across the Date Line, double‑check the calendar date: a 9 a.m. Wednesday slot in London lands at 10 p.m. Thursday in Samoa.
