Best Meeting Time: Seoul to Toronto
🕐 Live Timezone Overlap: Seoul & Toronto
Seoul and Toronto sit 13 hours apart, which makes finding a shared working window genuinely difficult. Toronto trails Seoul by 13 hours, meaning when Seoul's offices open at 9am on a Tuesday, Toronto is still in the early hours of Monday evening. There is no overlap between the two cities' standard 9am to 6pm working days. Any meeting between Seoul and Toronto requires at least one side to work outside normal hours.
Time Difference: Seoul and Toronto
Toronto is currently 13 hours behind Seoul. The live offsets are Seoul UTC+9 and Toronto UTC-4. Seoul does not observe daylight saving and Toronto observes daylight saving, so the offset shifts twice a year if both sides aren't already aligned.
Seoul holds a fixed UTC+9 offset year-round. South Korea does not observe DST. Toronto runs on Eastern Time and does observe North American DST, currently sitting at UTC-4. That puts the gap at 13 hours right now. In Toronto's winter, when Eastern Time reverts to UTC-5, the gap widens to 14 hours. The shift happens twice a year on Toronto's side alone, so Seoul-based teams need to track North American clock changes to avoid missed calls.
Best Times to Meet
With zero hours of overlap between Seoul and Toronto's working days, no in-hours meeting slot exists for both sides simultaneously. Every call demands a concession. The least painful arrangement is typically Seoul joining late, around 7pm to 8pm KST, while Toronto connects first thing in the morning, around 6am to 7am ET. Seoul teams should note that late Friday slots are uncommon due to the tradition of Friday team dinners. Monday to Thursday evenings in Seoul work best.

Tips for Scheduling Across Seoul and Toronto
- Seoul's Friday evenings are rarely free for business meetings; schedule recurring calls Monday to Thursday instead.
- Toronto's DST change widens the Seoul gap from 13 to 14 hours each winter; update recurring invites in November and March.
- A 7am Toronto start aligns with 8pm Seoul, keeping both sides within one hour of their working-day boundary.
- Block out Seollal and Chuseok well in advance: Seoul goes dark for 3 to 4 consecutive days during each festival.
- Toronto's Canada Day (1 July) and Boxing Day (26 December) are statutory holidays not shared with South Korea; check both calendars before sending invites.
Public Holidays and Working Weeks
Both cities follow a Monday to Friday working week, with 9am to 6pm as the standard pattern. Bay Street teams in Toronto are known to start as early as 8am, which can marginally help early-morning calls. Key dates to watch: Seoul observes Seollal in January or February and Chuseok in September or October, both bringing 3 to 4 day national closures. Toronto observes Canada Day on 1 July and Boxing Day on 26 December. Cross-city meetings must account for both calendars.
