History
How American Samoa keeps time.
American Samoa formally adopted Samoa Standard Time (UTC-11:00) under U.S. administration, aligning with its geographic position east of the 180° meridian. [1] Before the 1892 shift of the International Date Line, Samoa straddled timekeeping conventions shared with both Asia and the Americas. [2]
In 2011, neighboring independent Samoa shifted its time zone westward across the International Date Line — moving from UTC-11 to UTC+13 — effectively skipping a full calendar day to align with Australia and New Zealand trading partners. [3] American Samoa made no such change, remaining on UTC-11:00, which means the two Samoas are now almost a full day apart despite being only about 100 kilometers (60 miles) apart geographically. [4]
The decades-long separation in timekeeping between the two Samoas reflects divergent political and economic paths: American Samoa chose to remain anchored to the U.S. sphere of influence, while independent Samoa gravitated toward Asia-Pacific commerce. [5]
Did you know?
Things about American Samoa's time.
American Samoa sits in one of the most interesting timekeeping situations in the world. In 2011, just across the ocean, independent Samoa jumped from the eastern side of the International Date Line to the western side — switching from UTC-11 (the same zone American Samoa still uses) all the way to UTC+13. [1]
The result: American Samoa and independent Samoa are now nearly 24 hours apart despite being only about a 90-minute flight from Pago Pago to Apia. [2] If it's Friday in American Samoa, it's already Saturday in independent Samoa. Friends and family on opposite sides of this divide experience a full day's gap for calls, messages, and video chats — a rare modern example of neighboring communities living in different calendar days. [3]
Another practical point for travelers and remote workers: American Samoa also shares its UTC-11:00 time zone with Niue and Midway Atoll, and it does not observe daylight saving time at all. [4] That means when most U.S. clocks shift clocks forward in spring and back in fall, American Samoa stays fixed — creating a waxing and waning time gap with U.S. mainland time zones (Hawaii is UTC-10; U.S. Eastern is generally UTC-5). [5]
Frequently asked questions
Common questions about American Samoa's time zone, daylight saving rules, and how to handle it in software. Can't find what you need? Email [email protected].
- How does American Samoa's time compare to independent Samoa?
- American Samoa uses UTC-11:00 (Samoa Standard Time), while independent Samoa uses UTC+13:00 — a 24-hour (and one calendar day) difference, despite the two being roughly 100 km apart. In 2011, independent Samoa shifted westward across the International Date Line to align with Australia and New Zealand, widening the gap from 1 hour to a full day. [1][2]
- Does American Samoa observe daylight saving time?
- No. American Samoa stays on UTC-11:00 year-round and does not observe daylight saving time. This means U.S. time differences with the territory shift by an hour each spring and fall whenever U.S. clocks change. [3]
- What time zone is American Samoa in?
- American Samoa uses Samoa Standard Time (SST), UTC-11:00, named after its capital at Pago Pago. It does not observe daylight saving time. [4]
- Why did Samoa change its time zone but American Samoa did not?
- In 2011, independent Samoa shifted from UTC-11:00 to UTC+13:00 to align its trading week with Australia and New Zealand rather than the United States. [1] As a U.S. territory, American Samoa stayed anchored to U.S. time conventions, keeping UTC-11:00. [2]
- What other places share American Samoa's time zone?
- Pacific/Pago Pago (UTC-11:00) is shared with Niue and Midway Atoll — all remaining on standard time year-round. [4]
- When is the best time to call American Samoa from the U.S.?
- American Samoa is typically 5–7 hours behind U.S. Eastern Time (since it doesn't observe DST) and 6 hours behind Hawaii during U.S. daylight-saving periods. A good rule: late afternoon on the U.S. mainland is early morning in Pago Pago, so plan accordingly for calls and meetings.
- What does SST stand for in American Samoa?
- SST stands for Samoa Standard Time (UTC-11:00). It is not adjusted for daylight saving, unlike U.S. time zones. [4]
- Is American Samoa ahead or behind the U.S. mainland in time?
- American Samoa is behind. Depending on mainland time zones, it's 5–7 hours behind Eastern Time. Unlike U.S. mainland states, it never shifts forward for daylight saving, so the gap grows and shrinks by an hour through spring and fall. [3]
