This is useful when you are planning a business call between Singapore and Seoul, coordinating a product launch across regional teams, or confirming customer support coverage for North Asia.Add comparison cities if your schedule involves more offices: Click + Add City and search for cities that commonly work with Singapore and Korea, such as Singapore, Seoul, or Pyongyang if you need location-based context for regional operations. This is especially helpful for companies in electronics, shipping, finance, gaming, and cross-border e-commerce that manage work across Southeast Asia and the Korean market.
Drag across the grid to select a meeting window: Use the Select button if needed, then drag across the colored timeline to highlight a time range in purple, such as 9:00 to 12:00 SGT, which lines up with 10:00 to 13:00 KST. You can drag the center of the purple block to move the whole window or pull the left and right handles to resize it, which makes it easy to test whether a Singapore morning call still lands inside standard office hours in Korea.
Export the selected time for your team: After selecting a range, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link to send the confirmed slot to colleagues or clients. For example, a regional operations manager can export an ICS file for a Singapore-Korea supply chain meeting so everyone sees the appointment in local time without manually converting 15:00 SGT to 16:00 KST or 18:00 SGT to 19:00 KST.
SGT vs KST Offset Explained
Singapore Time (SGT) is UTC+8 and Korea Standard Time (KST) is UTC+9. That means KST is 1 hour ahead of SGT, and SGT is 1 hour behind KST. In practical terms, when it is 9:00 in Singapore, it is 10:00 in Korea, and when it is 18:00 SGT, it is 19:00 KST.
This one-hour gap is small enough for same-day coordination, which is why Singapore and Korea often overlap well for regional headquarters, technology teams, logistics operators, and financial services firms. A noon update from Singapore at 12:00 SGT reaches teams in Korea at 13:00 KST, while a mid-afternoon handoff at 15:00 SGT becomes 16:00 KST, still within a normal business day for many offices.
There is no seasonal shift to account for because SGT does not observe DST and KST does not observe DST. The time difference stays fixed throughout the year, so the relationship remains 1 hour in every month, which simplifies recurring meetings, travel planning, and cross-border support schedules between Singapore and North Korea or South Korea.
When SGT and KST Work Best for Meetings
Because the difference is only one hour, SGT and KST are well suited for live collaboration across the same workday. Teams can schedule leadership calls, software release reviews, procurement check-ins, or partner meetings without forcing very early mornings or late nights on either side.
A few common examples make this easy to remember: 9:00 SGT = 10:00 KST, 12:00 SGT = 13:00 KST, 15:00 SGT = 16:00 KST, and 18:00 SGT = 19:00 KST. These examples are useful for regional sales teams working between Singapore and Seoul, manufacturers coordinating with Korean suppliers, and travel planners arranging airport pickups, hotel check-ins, or event arrivals across both countries.
Why the Fixed 1-Hour Difference Matters
A fixed offset reduces scheduling mistakes in recurring operations. If a Singapore-based team holds a weekly call at 9:00 SGT, Korean participants can consistently join at 10:00 KST every week without any seasonal adjustment, which is valuable for remote teams, account managers, and customer success staff handling regular client touchpoints.
The same consistency helps with transport and commercial planning. Airlines, freight coordinators, and import-export teams moving goods between Singapore and South Korea can map departure and arrival communications more reliably, while media, gaming, and streaming businesses can coordinate campaign timings knowing that Korea will always be exactly one hour ahead of Singapore.
Frequently Asked Questions
What is the time difference between SGT and KST?
KST is 1 hour ahead of SGT, and SGT is 1 hour behind KST. SGT is UTC+8 and KST is UTC+9, so when it is 9:00 SGT, it is 10:00 KST. This fixed difference makes same-day scheduling straightforward for teams working between Singapore and Korea.
Is Korea ahead of Singapore time?
Yes, Korea Standard Time is ahead of Singapore Time by 1 hour. For example, 12:00 SGT = 13:00 KST and 15:00 SGT = 16:00 KST. This means Korean teams will generally start and end equivalent meeting slots one hour later on the clock than Singapore teams.
Do SGT and KST change during daylight saving time?
No. SGT does not observe DST and KST does not observe DST, so there is no daylight saving adjustment on either side. The difference remains 1 hour all year, which is especially helpful for recurring meetings, regional support rotations, and long-term project planning.
How do I convert Singapore Time to Korea Standard Time?
To convert from SGT to KST, use the fixed relationship that KST is 1 hour ahead of SGT. Practical examples include 9:00 SGT = 10:00 KST, 12:00 SGT = 13:00 KST, and 18:00 SGT = 19:00 KST. This is useful when confirming meeting invitations, webinar times, or departure schedules between Singapore and Korea.
Is Singapore in the same time zone as South Korea?
No, they are not in the same time zone. Singapore uses SGT (UTC+8), while South Korea uses KST (UTC+9), so South Korea is 1 hour ahead. Even though the difference is small, it still matters for exact meeting starts, event broadcasts, and airport transfer timing.
Is the SGT to KST difference always the same?
Yes, the difference is always the same because neither time zone uses daylight saving time. SGT stays at UTC+8 and KST stays at UTC+9, so the offset remains fixed at 1 hour throughout the year. That consistency is useful for businesses with regular Singapore-Korea communication and for travelers managing multi-city itineraries.
What time in Korea is 6 PM in Singapore?
18:00 SGT = 19:00 KST. This is a common conversion for end-of-day reporting, evening flight coordination, and regional handoff calls where a Singapore team wraps up work and a Korea-based team continues with the next stage.
