WST — West Samoa Time
See what WST means, where it is used, and how to compare or convert West Samoa Time to other time zones.
How to Convert WST to Other Time Zones
Open the WST converter page: Visit https://www.xconvert.com/time-converter/wst-time-zone to load the visual comparison grid with WST (West Samoa Time, UTC+13) already shown as the reference row. This page is useful when you need to line up work hours with Samoa, such as scheduling a tourism call with Apia-based operators, coordinating shipping updates across the South Pacific, or checking whether a support handoff overlaps with Australia, New Zealand, or the US West Coast.
Add comparison cities with “+ Add City”: Click “+ Add City” and search for cities that commonly interact with Samoa, such as Auckland for New Zealand travel and trade links, Sydney for aviation and regional business, and Los Angeles for international customer support or diaspora communication. Because WST is 13 hours ahead of UTC, adding multiple cities lets you immediately compare whether a daytime slot in Samoa lands in business hours, evening, or the previous calendar day elsewhere.
Drag across the grid to select a meeting window: Click “Select” if needed, then drag across the WST row to highlight a time range in purple; you can resize it with the left and right handles or move it by dragging the center. For example, if you drag 9:00 AM to 11:00 AM WST, that corresponds to 8:00 AM to 10:00 AM in Auckland during NZST, 6:00 AM to 8:00 AM in Sydney during AEST, and 2:00 PM to 4:00 PM in Los Angeles on the previous day during PDT—a practical check for whether a Samoa morning meeting works better for Oceania than for North America.
Export and share the selected time: Once your range is selected, use the export options shown on the page: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially useful if you are sending a confirmed call time to a distributed team, creating a calendar invite that automatically converts to each attendee’s local time, or sharing a link with a travel partner who needs to see the same WST-based schedule without recalculating manually.
About West Samoa Time (WST)
WST stands for West Samoa Time, the standard civil time used in Samoa. Its exact offset is UTC+13:00, which means local time in Samoa is 13 hours ahead of Coordinated Universal Time; when it is 12:00 noon UTC, it is 1:00 AM the next day in WST.
In practical terms, WST places Samoa among the world’s earliest time zones relative to Europe and the Americas, which is why calls from Samoa often fall on the previous calendar day in the United States and Canada. For example, 9:00 AM WST is 8:00 PM UTC on the previous day, so anyone coordinating with London, New York, or San Francisco needs to check both the hour difference and the date difference.
The time zone is primarily associated with Samoa, whose principal urban center is Apia on the island of Upolu. Samoa has a population of roughly 225,000 people, and WST is relevant for government services, tourism operators, shipping schedules, schools, churches, and regional business links with New Zealand, Australia, Fiji, and other Pacific economies.
WST shares the same UTC+13 offset with several other abbreviations at certain times of year, including FJST, NZDT, PHOT, TKT, and TOT, but those abbreviations refer to different territories or seasonal rules. The matching offset does not mean they are interchangeable year-round, because other zones may move when daylight saving starts or ends while Samoa remains on WST.
WST and Daylight Saving Time
For the current configuration provided here, WST does not observe daylight saving time, so the offset remains UTC+13:00 all year. That means there is no spring-forward or fall-back transition in 2026, and no switch to a separate daylight time abbreviation during the year.
This fixed-offset behavior is important for planning recurring meetings because Samoa’s local clock stays stable even when comparison cities change. For instance, if you compare WST with Auckland, Sydney, London, or Los Angeles, the time difference can shift seasonally because those places may enter or leave DST, not because WST changes.
Historically, Samoa has changed its time policies before, including major calendar and offset adjustments in past years, so older schedules and archived timestamps may need careful interpretation. For current scheduling on xconvert, however, you should treat WST as a constant UTC+13 zone with no DST transition dates in 2026.
Frequently Asked Questions
What does WST stand for?
WST stands for West Samoa Time. It is the standard time used in Samoa and is set at UTC+13:00, meaning it runs 13 hours ahead of Coordinated Universal Time.
Is WST the same as GMT?
No, WST is not the same as GMT. GMT is UTC+0, while WST is UTC+13, so WST is 13 hours ahead of GMT; when it is 9:00 AM GMT, it is 10:00 PM WST on the same day.
Which cities use WST?
The principal city associated with WST is Apia, the capital of Samoa. In most practical searches, users asking which cities use WST are really asking about Samoa’s local time, and Apia is the main reference point for flights, hotels, government offices, and business scheduling.
What is the UTC offset for WST?
The UTC offset for WST is +13:00. This means you add 13 hours to UTC to get local WST time, or subtract 13 hours from WST to convert back to UTC.
When does WST change?
For the current rule set on this page, WST does not change during the year. There are no daylight saving transition dates in 2026, so Samoa stays on UTC+13 continuously from January through December.
Is WST ahead of New Zealand time?
WST is not always the same relative distance from New Zealand, because New Zealand changes between standard time and daylight time. During New Zealand Standard Time (NZST, UTC+12), WST is 1 hour ahead; during New Zealand Daylight Time (NZDT, UTC+13), WST and New Zealand daylight time are the same clock time.
How far ahead is WST from UTC?
WST is 13 hours ahead of UTC. A simple example is that 6:00 PM UTC becomes 7:00 AM WST the next day, which is why date rollover is a common issue when booking flights, sending deadlines, or arranging calls with Europe or North America.
Does WST observe daylight saving time?
No, WST does not currently observe daylight saving time on this page’s configuration. That makes it easier to schedule recurring events in Samoa, because the local offset remains fixed at UTC+13, even though the other city in your comparison may still shift seasonally.
