Current Time in IANA US/Samoa Timezone

Overview and Applicability

The US/Samoa zone applies exclusively to American Samoa, a group of five main islands (Tutuila, Aunu'u, Ofu, Olosega, and Ta'ū) and two coral atolls (Rose Atoll and Swains Island). The territory's capital, Pago Pago, is the primary urban center. This zone is used by approximately 55,000 residents, along with government offices, businesses, and the international airport. It is important to note that the neighboring independent nation of Samoa uses a different time zone (UTC+13:00), despite the shared name.

Offset and Abbreviation

The standard offset of UTC-11:00 means that when it is noon at the prime meridian (UTC), it is 1:00 AM in American Samoa. The abbreviation SST stands for Samoa Standard Time. This offset places the zone among the last to see each new calendar day; for example, when it is midnight on January 1 in American Samoa, most of the world has already entered the new year. Other IANA zones sharing the same UTC-11:00 offset include Pacific/Midway (Midway Atoll), Pacific/Niue (Niue), and Pacific/Pago_Pago (which is an alias for US/Samoa).

Daylight Saving Time: Why None Is Observed

American Samoa does not observe daylight saving time (DST). The territory lies near the equator (around 14°S latitude), resulting in relatively consistent day length throughout the year. The sun rises and sets at nearly the same times year-round, making DST unnecessary. Consequently, the offset remains UTC-11:00 every day of the year. This contrasts with many US states and territories that shift clocks, but aligns with other equatorial regions. The lack of DST simplifies scheduling for residents but requires careful attention when coordinating with DST-observing areas, as the time difference can vary seasonally.

Main Countries and Cities

The only territory using US/Samoa is American Samoa. Key locations include:

• Pago Pago (capital and largest city, on Tutuila Island)
• Tafuna (village and home to Pago Pago International Airport)
• Fagatogo (seat of government)
• Leone (western Tutuila)
• Ofu and Ta'ū (in the Manu'a Islands)

Other territories in the same offset zone include Midway Atoll (US minor outlying islands) and Niue (self-governing in free association with New Zealand). However, these are separate IANA zones (Pacific/Midway and Pacific/Niue) and are not part of the US/Samoa zone.

Practical Guidance for Business and Calls

Because US/Samoa does not observe DST, the time difference with mainland US varies. During US daylight saving time (March to November), American Samoa is 6 hours behind Eastern Time (ET) and 3 hours behind Pacific Time (PT). During US standard time (November to March), the difference is 5 hours behind ET and 2 hours behind PT. For example, when it is 9:00 AM ET in New York during DST, it is 3:00 AM SST in American Samoa. To find a suitable meeting time, aim for overlap during the US business morning (e.g., 8:00 AM ET = 2:00 AM SST, which is early in American Samoa). Late US afternoon (e.g., 4:00 PM ET = 10:00 AM SST) works better. For calls with Asia-Pacific regions, note that Sydney (UTC+10:00 or +11:00 DST) is 21-22 hours ahead; Tokyo (UTC+9:00) is 20 hours ahead. Scheduling requires checking current offsets due to DST variations elsewhere.

Key Points to Remember

• US/Samoa is fixed at UTC-11:00 all year; no clock changes.
• SST = Samoa Standard Time.
• American Samoa is the only user; do not confuse with independent Samoa (UTC+13:00).
• Time difference with US mainland shifts by one hour twice a year due to US DST.
• Business hours overlap best with US East Coast in late afternoon ET (10:00 AM-12:00 PM SST).
