Best Meeting Time: Toronto to Seoul
🕐 Live Timezone Overlap: Toronto & Seoul
Toronto and Seoul sit 13 hours apart, which means one city is always well outside its working day when the other is in the middle of it. There is no overlap between standard 9am to 6pm working hours in either city. Every meeting between the two requires at least one side to attend before 9am or after 6pm. That asymmetry is the single most important fact to pin down before sending any calendar invite.
Time Difference: Toronto and Seoul
Seoul is currently 13 hours ahead of Toronto. The live offsets are Toronto UTC-4 and Seoul UTC+9. Toronto observes daylight saving and Seoul does not, so the offset shifts twice a year if both sides aren't already aligned.
Toronto currently runs at UTC-4, having shifted from its standard UTC-5 under North American DST. Seoul stays fixed at UTC+9 all year. South Korea does not observe DST. That means the gap between Toronto and Seoul is 13 hours while Toronto is on DST (summer), widening to 14 hours once Toronto returns to standard time each autumn. Teams scheduling recurring calls need to update their calendar entries twice a year as Toronto's clocks change.
Best Times to Meet
With zero hours of working-hour overlap between Toronto and Seoul, every call demands a compromise. The least disruptive arrangement is typically an early morning slot for Seoul, around 7am to 8am KST, which lands at 6pm to 7pm the previous evening in Toronto. Toronto's Bay Street culture of arriving by 8am means an early Seoul start is not unreasonable from the Canadian side either. Avoid late Friday slots for Seoul: business meetings late on Fridays are uncommon given the hoesik culture there.

Tips for Scheduling Across Toronto and Seoul
- There is no working-hours overlap between Toronto and Seoul; schedule one side outside 9am to 6pm every time.
- Toronto's UTC offset changes twice a year: update recurring Seoul calls each time North American DST shifts.
- A 7am to 8am Seoul start equals roughly 6pm to 7pm the prior evening in Toronto, the least painful split.
- Block out Seollal and Chuseok in your shared calendar: Seoul closes for 3 to 4 days on both occasions.
- Canada Day (1 July) and Boxing Day (26 December) are Canadian statutory holidays; Seoul teams will be working those days.
Public Holidays and Working Weeks
Both Toronto and Seoul follow a Monday to Friday working week, with 9am to 6pm as the standard window. Toronto's statutory holidays include Canada Day on 1 July and Boxing Day on 26 December, neither of which Seoul observes. Seoul closes for 3 to 4 days during Seollal and again for Chuseok, both with movable dates in January or February and September or October respectively. Cross-city scheduling must account for both holiday calendars to avoid missed meetings.
