See the current 1-hour time difference between Singapore Time and Korea Standard Time, with overlap hours for planning calls and meetings.
How to Find the Time Difference Between SGT and KST
Open the SGT vs KST converter: Go to https://www.xconvert.com/time-converter/sgt-vs-kst to open the visual comparison page with Singapore Time (SGT) and Korea Standard Time (KST) already loaded in the grid. This page is useful when you are scheduling a sales call between Singapore and Seoul, coordinating a product launch across APAC teams, or checking whether Korean market hours overlap with business hours in Singapore.
Add comparison cities if your schedule involves more regions: Click + Add City and search for places such as Tokyo, Hong Kong, or Sydney if you work in electronics, shipping, finance, or regional headquarters operations that span East Asia and Oceania. For example, adding Tokyo helps compare Japan business hours with both Singapore and South Korea, while Hong Kong is useful for banking and trade coordination because it shares the same UTC+8 base as Singapore.
Drag across the grid to select a meeting window: Click Select to enter selection mode, then drag across the SGT or KST row to highlight a time range in purple; you can adjust the left and right handles or drag the center to move the whole block. For example, if you drag 9:00 AM to 11:00 AM SGT, the tool will show 10:00 AM to 12:00 PM KST, confirming that South Korea is 1 hour ahead of Singapore and that a normal Singapore morning meeting still lands comfortably within Seoul office hours.
Export and share the selected time range: Once a range is selected, use the export options for ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link depending on how you coordinate with your team. This is especially useful for sending a confirmed APAC meeting slot to colleagues in Seoul and Singapore so each person sees the event in local time automatically without manually converting UTC offsets.
SGT vs KST Offset Explained
Singapore Time (SGT) is UTC+8, while Korea Standard Time (KST) is UTC+9, so KST is exactly 1 hour ahead of SGT all year. That means when it is 9:00 AM in Singapore, it is 10:00 AM in Seoul, and when it is 6:00 PM in Singapore, it is 7:00 PM in South Korea. This small but important gap matters for same-day meetings, customer support coverage, and regional handoffs because Korean teams will finish the workday one hour earlier relative to Singapore-based colleagues.
There is no daylight saving time currently observed in either Singapore or South Korea, so the difference remains stable in January, June, and December with no seasonal clock changes. SGT stays fixed at UTC+8 throughout the year, and KST stays fixed at UTC+9, which makes recurring scheduling easier than with regions such as the US or Europe where offsets shift in March and October or November. For remote teams, this means a weekly 2:00 PM Singapore meeting will always be 3:00 PM in Korea, regardless of season.
Singapore is a city-state in Southeast Asia with a population of about 5.9 million, and it serves as a major hub for banking, shipping, aviation, semiconductors, and regional corporate headquarters. South Korea has a population of about 51 million, with Seoul as a major center for technology, automotive manufacturing, gaming, consumer electronics, and entertainment, including companies such as Samsung, LG, Hyundai, Kakao, and Naver. Because both economies are deeply integrated into Asian supply chains, the 1-hour difference is commonly relevant for procurement calls, logistics coordination, and cross-border executive meetings.
For practical planning, the overlap between standard office hours is strong: 9:00 AM to 6:00 PM SGT corresponds to 10:00 AM to 7:00 PM KST. This means a late-afternoon Singapore meeting at 5:30 PM SGT becomes 6:30 PM KST, which may still work for some Korean teams but is closer to end-of-day. If you need the broadest overlap for finance, SaaS operations, or manufacturing support, 10:00 AM to 4:00 PM SGT usually maps well to 11:00 AM to 5:00 PM KST.
Frequently Asked Questions
What is the exact time difference between SGT and KST?
Korea Standard Time is 1 hour ahead of Singapore Time. In exact terms, SGT = UTC+8 and KST = UTC+9, so if it is 8:00 AM in Singapore, it is 9:00 AM in South Korea on the same calendar day.
Does the time difference between Singapore and South Korea ever change during the year?
No, the difference does not change seasonally under current rules because neither country currently observes daylight saving time. Singapore remains on UTC+8 year-round, and South Korea remains on UTC+9, so the gap stays fixed at 1 hour in every month.
Is South Korea ahead of Singapore or behind Singapore?
South Korea is ahead of Singapore by 1 hour. This means Korean offices start and end their local business day earlier relative to Singapore teams, so a meeting scheduled for 4:00 PM in Singapore will already be 5:00 PM in Korea.
What is the best meeting time for teams in Singapore and Seoul?
A practical shared window is usually 10:00 AM to 4:00 PM SGT, which corresponds to 11:00 AM to 5:00 PM KST. This range works well for regional management calls, customer onboarding, and engineering syncs because it avoids very early starts in Singapore and late-evening meetings in Korea.
How do I use the xconvert grid to compare SGT and KST visually?
On the xconvert page, the comparison is done through a 24-hour horizontal grid rather than a text box for entering times. Click Select, drag across a block of hours on the SGT or KST row, and the highlighted purple range will line up across both time zones so you can instantly see whether a proposed slot lands in work hours, evening, or night.
Are Singapore and South Korea on the same date at the same time?
Almost always yes, because the difference is only 1 hour and both are in East and Southeast Asia. However, around midnight the displayed local clock time differs, so 11:30 PM in Singapore becomes 12:30 AM the next day in South Korea, which can affect deadlines, reporting cutoffs, and calendar dates.
Why is the SGT vs KST comparison useful for business scheduling?
Singapore and South Korea are both major Asian business centers, but they support different industry strengths that often require daily coordination. Singapore is heavily used for regional headquarters, commodities, aviation, and finance, while South Korea is prominent in electronics, automotive, gaming, and manufacturing, so even a 1-hour offset matters for shipment approvals, executive calls, and support escalations.
Can I export a selected Singapore–Korea meeting time to a calendar?
Yes, after you highlight a time range on the grid, the page provides ICS download, Google Calendar, Gmail, Copy to clipboard, and Share link options. This is useful when you want a Seoul-based client, a Singapore operations manager, and other APAC stakeholders to receive the same meeting slot in their own local time without manual conversion errors.
