KST vs SGT Time Difference
See the 1-hour difference between Korea Standard Time and Singapore Time, check overlap hours, and plan meetings faster.
KST and SGT Difference
KST is UTC+9 and SGT is UTC+8, so Korea Standard Time is 1 hour ahead of Singapore Time year-round.
No DST in Either
Neither KST nor SGT currently observes daylight saving time, so the time difference stays consistent without seasonal shifts.

How to Find the Time Difference Between KST and SGT
Open the comparison page: Visit https://www.xconvert.com/time-converter/kst-vs-sgt to load a visual grid with KST and SGT aligned on the same 24-hour timeline. This view is useful when you are scheduling a call between teams in South Korea and Singapore, such as a regional sales update, a logistics handoff, or a product meeting covering Northeast and Southeast Asia.
Add comparison cities if your meeting includes more regions: Click + Add City and search for other hubs that often work with Korea and Singapore, such as Tokyo, Hong Kong, or Sydney. This helps multinational teams in electronics, shipping, finance, and e-commerce compare whether a KST-based planning session also fits partners across Asia-Pacific.
Drag to select a working window: Click Select if needed, then drag across the colored timeline on the KST row to highlight a range in purple, such as 9:00 to 12:00 KST. The grid immediately shows the matching SGT time as 8:00 to 11:00 SGT, which is useful for confirming that a Seoul morning meeting still lands inside standard office hours in Singapore.
Export the result for your team: After selecting the time range, use the export options shown on the page: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link. This is especially practical when a regional operations team wants to send one confirmed meeting window to colleagues in Korea and Singapore so everyone receives the correct local time automatically.
KST vs SGT Offset Explained
KST is Korea Standard Time (UTC+9), and SGT is Singapore Time (UTC+8). KST is 1 hour ahead of SGT, which means SGT is -1 hours behind KST. In practical terms, when it is 9:00 in KST, it is 8:00 in SGT, and when it is 18:00 in KST, it is 17:00 in SGT.
This one-hour gap is small, but it matters in day-to-day scheduling. A team starting work at 9:00 KST in Seoul reaches colleagues in Singapore at 8:00 SGT, which may be early for some offices but still workable for regional planning, customer support coordination, and supply-chain updates. Likewise, a 15:00 KST meeting appears as 14:00 SGT, a convenient overlap for afternoon reviews, vendor calls, and APAC management check-ins.
There is no seasonal clock shift to account for between these two time zones. KST does not observe DST, and SGT does not observe DST, so the 1-hour difference remains the same throughout the year. That consistency is helpful for recurring meetings, especially for companies running fixed weekly schedules between South Korea and Singapore without needing to adjust calendars in spring or autumn.
KST is used in North Korea and South Korea, while SGT is the standard time used in Singapore’s business environment. Because both time zones stay fixed year-round, industries such as electronics manufacturing, semiconductor supply chains, regional banking, aviation planning, and cross-border e-commerce can keep stable meeting patterns without seasonal confusion.
KST and SGT in Daily Scheduling
The most useful way to think about this comparison is through direct business-hour overlap. A 12:00 KST lunch-hour checkpoint in Korea is 11:00 SGT in Singapore, which often works well for pre-lunch coordination on the Singapore side. A 15:00 KST project review becomes 14:00 SGT, making it a practical time for shared working sessions, status calls, and partner updates.
This alignment is especially relevant for companies operating across East and Southeast Asia. South Korea is a major base for technology, automotive, electronics, and manufacturing, while Singapore is a regional hub for finance, shipping, cloud infrastructure, and multinational headquarters. Because the time gap is only one hour, teams can usually schedule same-day decisions without forcing anyone into very early mornings or late evenings.
Best Times for Calls Between Korea and Singapore
For most office-based teams, morning and early afternoon are the easiest windows to share. If a manager in Korea proposes 9:00 KST, the Singapore side sees 8:00 SGT, which can work for early-start teams in finance, logistics, and operations. If the Korean side proposes 18:00 KST, that becomes 17:00 SGT, often suitable for end-of-day wrap-ups, executive approvals, or final coordination before regional deadlines.
The stable offset also helps with recurring meetings. A weekly product sync set for 12:00 KST will always be 11:00 SGT, and an afternoon review at 15:00 KST will always be 14:00 SGT. Since neither side changes clocks for daylight saving time, teams do not need to revise invitations during different parts of the year.
Frequently Asked Questions
What is the time difference between KST and SGT?
KST is 1 hour ahead of SGT. KST is UTC+9, while SGT is UTC+8, so Singapore runs -1 hours behind Korea Standard Time. For example, 9:00 KST = 8:00 SGT and 15:00 KST = 14:00 SGT.
Is Korea ahead of Singapore time?
Yes. Korea Standard Time is ahead of Singapore Time by 1 hour. That means if a team in Seoul starts a meeting at 12:00 KST, colleagues in Singapore join at 11:00 SGT.
Do KST and SGT ever change because of daylight saving time?
No. KST does not observe DST, and SGT does not observe DST. Because neither time zone changes clocks during the year, the difference stays fixed at 1 hour, which makes recurring scheduling much simpler.
What is 9 AM KST in Singapore time?
9:00 KST = 8:00 SGT. This is a common conversion for regional morning calls, especially when Korea-based teams begin work slightly earlier than Singapore-based colleagues.
What is 12 PM KST in Singapore time?
12:00 KST = 11:00 SGT. This is often a practical time for cross-border meetings because it lands before lunch in Singapore and at midday in Korea, making it suitable for status reviews and short decision meetings.
What is 3 PM KST in Singapore time?
15:00 KST = 14:00 SGT. This is one of the easiest windows for collaboration because both sides are comfortably inside normal office hours and can still follow up before the end of the workday.
What is 6 PM KST in Singapore time?
18:00 KST = 17:00 SGT. This timing is useful for end-of-day handoffs, especially when teams need to finalize updates, approve documents, or close out regional tasks before offices shut.
Is it easy to schedule meetings between South Korea and Singapore?
Yes, because the gap is only 1 hour and it does not change seasonally. That makes coordination much easier than with Europe or North America, and it supports regular collaboration in industries such as technology, trade, logistics, finance, and regional headquarters operations.
Which countries use KST?
KST is used in North Korea and South Korea. This matters when coordinating with Korean offices, suppliers, manufacturing partners, or customer-facing teams that operate on Korea Standard Time.
