SST — Samoa Standard Time
See what SST means, where it is used, its UTC-11 offset, and how to compare or convert it with other time zones.
Meaning and Usage Areas
SST stands for Samoa Standard Time and uses a fixed UTC-11 offset. It is used in American Samoa year-round.
No DST Time Changes
SST does not observe daylight saving time, so the UTC-11 offset stays the same throughout the year. This helps avoid seasonal clock changes when scheduling.

This view is useful when you are planning a call with contacts in American Samoa, such as government offices, local service providers, or partners in Pago Pago who work on UTC-11 year-round.Add comparison cities: Click + Add City and search for the cities you want to compare against SST. A practical setup is to add cities tied to your workflow, such as regional business hubs, airline connection points, or the home offices of remote teammates, so you can see how working hours in American Samoa line up against other schedules on the same 24-hour grid.
Select a meeting window on the grid: Click Select to enter selection mode, then drag across the colored timeline in the SST row to highlight a time range in purple. You can drag the center of the selection to shift the whole window or use the left and right handles to resize it, which is especially helpful when you are trying to find overlap between daytime hours in Pago Pago and office hours in other locations.
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.

About Samoa Standard Time (SST)
SST stands for Samoa Standard Time. Its exact offset is UTC-11, which means local time in SST is 11 hours behind Coordinated Universal Time.
Samoa Standard Time is used in American Samoa. Principal cities and populated places using SST include Pago Pago, Tāfuna, Ta`ū, and Taulaga, making it the standard civil time used across the territory for local scheduling, administration, and daily business activity.
SST does not observe daylight saving time and has no counterpart. That means the abbreviation stays the same throughout the year, which simplifies recurring meeting planning because the local clock in American Samoa does not switch seasonally.
SST also shares its UTC-11 offset with the abbreviations NUT and X. When comparing time zones on a world clock or scheduling grid, this is useful because different labels can represent the same underlying offset even though they apply to different contexts.
SST and Daylight Saving Time
Samoa Standard Time does not observe DST. There is no seasonal clock change, so SST does not switch forward or backward at any point during the year.
SST also has no daylight saving counterpart, so there is no alternate summer abbreviation to watch for in calendars or meeting invitations. For businesses and remote teams, this means American Samoa remains on UTC-11 continuously, which reduces confusion when setting long-term recurring calls.
Because there is no DST transition, there are no start dates, end dates, or annual switch times to track for SST. If you are coordinating with cities that do change their clocks seasonally, the difference between those locations and American Samoa can shift during the year even though SST itself remains fixed.
