Meaning and Where Used
SST stands for Samoa Standard Time and has a fixed offset of UTC-11. It is used in American Samoa year-round.
No Daylight Saving Time
SST does not observe daylight saving time, so the UTC-11 offset stays the same throughout the year. The page tracks timezone rules using the IANA timezone database.
Convert SST to Others

How to Convert SST to Other Time Zones
Open the SST converter page: Go to https://www.xconvert.com/time-converter/sst-time-zone to open the visual comparison grid with SST (Samoa Standard Time) already loaded. This view is useful when you need to line up work hours in American Samoa with another location, such as scheduling a call with a contact in Pago Pago or planning a travel-related handoff tied to local time there.
Add comparison cities: Click + Add City and search for the cities you want to compare against SST. A practical setup is to add places your team or contacts use most often, then compare their rows against Pago Pago, Ta`ū, Taulaga, or Tāfuna so you can see where business hours, evening periods, and overnight gaps overlap on the same 24-hour timeline.
Select a meeting window on the grid: Click Select to enter selection mode, then drag across the colored timeline on the SST row to highlight a time range in purple. You can drag the center of the selection to move it or use the left and right handles to resize it, which is especially helpful when you are testing whether a morning window in Samoa Standard Time, UTC-11, lands inside workable hours for another office or traveler itinerary.
Export and share the result: Once a time range is selected, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This makes it easy to send a confirmed SST-based meeting slot to remote teammates, include it in a calendar invite, or share a direct link with anyone coordinating around American Samoa time.
About Samoa Standard Time (SST)
SST stands for Samoa Standard Time. It uses a fixed offset of UTC-11, which means local time in this zone is 11 hours behind Coordinated Universal Time throughout the year.
Samoa Standard Time is used in American Samoa. Principal cities and communities using this time zone include Pago Pago, Ta`ū, Taulaga, and Tāfuna, so SST is the local standard reference for daily schedules, appointments, transport timing, and cross-border coordination in that region.
SST does not observe daylight saving time and has no counterpart. That means there is no seasonal switch to a summer time version, and the abbreviation remains SST year-round rather than changing to a daylight variant.
Other abbreviations that share the same UTC-11 offset include NUT and X. When comparing schedules, this can help if you are matching timestamps or system logs that use different abbreviations but still represent the same offset.
SST and Daylight Saving Time
Samoa Standard Time does not observe DST. There is no seasonal clock change, no switch to a daylight time abbreviation, and no part of the year when SST moves away from UTC-11.
Because SST has no daylight saving counterpart, there are no DST transition dates to track for the current year. This is useful for recurring meetings and operational schedules because the local time in American Samoa stays on the same standard offset all year.
For planning purposes, that consistency matters. If you are organizing regular calls, travel timing, or support coverage involving Pago Pago, Ta`ū, Taulaga, or Tāfuna, you do not need to account for a local clock change within the SST zone itself.

Are there other abbreviations with the same offset as SST?
Yes. NUT and X share the same UTC-11 offset as SST. This can be useful when reading technical timestamps, aviation references, or scheduling systems that display a different abbreviation but still map to the same offset.
