SGT to PST Difference
Compare Singapore Time (UTC+8) with Pacific Standard Time (UTC-8) in a live time difference view. See the current gap hour by hour so you can quickly plan calls across both zones.
DST Changes the Gap
Singapore Time does not observe DST, while Pacific Standard Time shifts to daylight saving time in part of the year. The page tracks these changes automatically using the IANA timezone database so the offset stays accurate.
Best Meeting Time Overlap
Find the most practical meeting windows between Singapore and Pacific time with visual hour grids and overlap highlights. Export selected times to ICS, Google Calendar, or Gmail for faster scheduling.
SGT (Singapore Time, UTC+8) is 16 hours ahead of PST (Pacific Standard Time, UTC-8), which means Pacific Standard Time is 16 hours behind Singapore Time.

How to Find the Time Difference Between SGT and PST
Open the SGT vs PST page: Visit
https://www.xconvert.com/time-converter/sgt-vs-pstto see Singapore Time pre-loaded against Pacific Standard Time on the visual comparison grid. This view is useful when you are planning a call between Singapore teams and colleagues on the west coast of the United States, Canada, or Mexico, where Pacific Standard Time is used during standard time.Add comparison cities: Click + Add City and search for cities that matter to your schedule, such as Singapore alongside Los Angeles, Vancouver, or Tijuana for technology, logistics, media, and cross-border operations. Adding these rows helps remote teams compare how a workday in Singapore overlaps with Pacific Standard Time markets and office hours across North America.
Select a meeting window on the grid: Click Select, then drag across the colored timeline on the Singapore row to highlight a time range in purple, such as 9:00 to 12:00 SGT. That selection shows the practical impact of the 16-hour gap: 9:00 SGT = 17:00 PST (previous day) and 12:00 SGT = 20:00 PST (previous day), confirming that a Singapore morning meeting lands on the previous evening in Pacific Standard Time.
Adjust and export the result: Drag the center of the purple block to move the full range, or use the left and right handles to resize it until you find a workable overlap, then use ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. These export options are useful when a Singapore operations team needs to send a confirmed handoff window to Pacific Standard Time colleagues so everyone receives the meeting in their own local calendar or message workflow.
SGT vs PST Offset Explained
Singapore Time uses UTC+8, while Pacific Standard Time uses UTC-8. The fixed difference on this page is 16 hours, so SGT is 16 hours ahead of Pacific Standard Time, and Pacific Standard Time is 16 hours behind Singapore Time. In practical terms, when it is 15:00 in Singapore, it is 23:00 PST on the previous day, and when it is 18:00 in Singapore, it is 2:00 PST.
Singapore Time does not observe daylight saving time, so its offset remains UTC+8 throughout the year. Pacific Standard Time is specifically the standard-time abbreviation for the Pacific zone, and its daylight saving counterpart is PDT. That distinction matters for scheduling because companies coordinating between Singapore and the west coast of North America often need to confirm whether they are working with Pacific Standard Time specifically, especially for support coverage, software releases, and cross-border customer service.
The 16-hour gap creates a strong previous-day effect for Singapore-to-Pacific scheduling. A standard Singapore business morning often maps to the previous evening in Pacific Standard Time, as shown by 9:00 SGT = 17:00 PST (previous day) and 12:00 SGT = 20:00 PST (previous day). This is especially relevant for finance teams closing books across regions, e-commerce operators managing fulfillment updates, and distributed engineering teams planning handoffs between Asia and North America.
Scheduling Between Singapore and Pacific Standard Time
Singapore is the only country using Singapore Time, while Pacific Standard Time is used in parts of Canada, Mexico, and the United States. That makes this comparison common for regional headquarters in Singapore working with west coast partners in North American technology, entertainment, manufacturing, and import-export operations. The time gap is large enough that many teams rely on either Singapore late afternoon or Pacific Standard Time early morning for live communication.
The example conversions on this page show why overlap planning matters. If a team in Singapore proposes 18:00 SGT, that corresponds to 2:00 PST, which is usually unsuitable for a live meeting. By contrast, 9:00 SGT, 12:00 SGT, and 15:00 SGT map to 17:00, 20:00, and 23:00 PST on the previous day, which can work better for evening support shifts, media review cycles, or urgent production incidents that need follow-the-sun coverage.
For travel and operations planning, this comparison is also useful when coordinating departures, arrivals, and customer communications across the Pacific. A Singapore-based travel coordinator arranging an itinerary for teams moving between Southeast Asia and Pacific coast destinations can use the grid to explain why a same-calendar-day assumption often fails. The previous-day shift is one of the most important details to communicate clearly in tickets, meeting invites, and service-level agreements.
Frequently Asked Questions
What is the time difference between SGT and Pacific Standard Time?
Singapore Time is 16 hours ahead of Pacific Standard Time. Put the other way around, Pacific Standard Time is 16 hours behind Singapore Time, so a Singapore morning often corresponds to the previous day in Pacific Standard Time.
Is Singapore Time ahead of PST or behind it?
Singapore Time is ahead of Pacific Standard Time by 16 hours. For example, 15:00 SGT = 23:00 PST, and 9:00 SGT = 17:00 PST on the previous day, which is why Singapore-based teams often need to schedule with west coast colleagues in the evening.
Why does SGT to PST often show the previous day?
The difference is large enough that many Singapore daytime hours fall into the prior calendar date in Pacific Standard Time. For instance, 12:00 SGT = 20:00 PST (previous day), so if someone in Singapore schedules a noon update, a Pacific Standard Time participant receives it as an evening event the day before.
Does Singapore Time observe daylight saving time?
Singapore Time does not observe daylight saving time, so it remains at UTC+8 all year. Pacific Standard Time is the standard-time abbreviation for the Pacific zone, and its daylight saving counterpart is PDT, which is important when confirming seasonal schedules with teams in Canada, Mexico, and the United States.
What are some common SGT to PST conversion examples?
Several useful anchor points make planning easier: 9:00 SGT = 17:00 PST (previous day), 12:00 SGT = 20:00 PST (previous day), 15:00 SGT = 23:00 PST (previous day), and 18:00 SGT = 2:00 PST. These examples help with business calls, release windows, and support handoffs because they show exactly when a Singapore work block lands in Pacific Standard Time.
Is PST Pacific Standard Time or Pitcairn Standard Time?
On this page, PST means Pacific Standard Time (UTC-8). PST can also mean Pitcairn Standard Time (UTC-8), and if you need that meaning instead, use /time-converter/pst-pitcairn-time-zone to avoid mixing the two pages.
