Best Meeting Time: Seoul to Singapore
🕐 Live Timezone Overlap: Seoul & Singapore
Seoul and Singapore sit just one hour apart, making this one of the more forgiving time-zone pairings in Asia-Pacific. Seoul runs ahead at UTC+9, Singapore at UTC+8. That slim gap means an 8-hour overlap window across a standard 9am-6pm working day, so both teams can share most of the afternoon without anyone dialling in before breakfast or after dinner. The practical challenge is less about clock arithmetic and more about aligning two distinct holiday calendars.
Time Difference: Seoul and Singapore
Singapore is currently 1 hour behind Seoul. The live offsets are Seoul UTC+9 and Singapore UTC+8. Seoul does not observe daylight saving and Singapore does not, so the offset shifts twice a year if both sides aren't already aligned.
Seoul operates at UTC+9 year-round. Singapore operates at UTC+8 year-round. Neither city observes daylight saving time, so the gap between them is a fixed one hour, every day, every month. Seoul is always one hour ahead of Singapore. No bi-annual clock changes mean no seasonal disruption to your recurring meeting schedule. What you set up in January will still be accurate in July.
Best Times to Meet
The 8-hour overlap runs from 10am to 6pm in Seoul and 9am to 5pm in Singapore. Inside that 8-hour window, the cleanest slot is typically 10am to 12pm Seoul time (9am to 11am Singapore time). This keeps Seoul participants in their morning, before working hours stretch later in the day at many Seoul firms, and catches Singapore at the start of its 9am-6pm norm. Avoid late-Friday slots for Seoul: business meetings on Friday afternoons are uncommon given the hoesik culture.

Tips for Scheduling Across Seoul and Singapore
- Neither Seoul nor Singapore changes clocks, so a 10am Seoul standing invite stays accurate all year without adjustment.
- Check Seollal and Chuseok dates early: Seoul offices can be closed for 3-4 consecutive days around each festival.
- Singapore's Chinese New Year holiday overlaps closely with Seoul's Seollal period, compressing usable meeting weeks in January or February.
- Avoid scheduling Seoul meetings on Friday afternoons: hoesik team dinners make late-Friday business calls uncommon in South Korea.
- For Singapore participants, a 9am start is within the firm norm; Seoul joins at 10am, so neither side takes an unsociable slot.
Public Holidays and Working Weeks
Both Seoul and Singapore follow a Monday-to-Friday working week with 9am-6pm as the standard window. Seoul faces 3-4 day national closures for Seollal and Chuseok, both on movable lunar dates in January or February and September or October respectively. Singapore observes two public holidays for Chinese New Year, also in January or February, with extended absences common around that period. Any cross-city meeting schedule should account for both calendars simultaneously to avoid missed connections.
