About
Working across 0 hours of time difference
Tokyo and Seoul are close enough (0 hours) that a normal workday call poses little challenge. Most slots between 10 AM and 4 PM in either city land cleanly in the other's business hours. Pick a time that suits the agenda; both teams can attend without disruption.
Daylight Saving Time can shift the gap by an hour twice a year. The North American DST window does not align with the European one, so the offset between Tokyo and Seoul can drift in late March and again in early November. Use this page to re-check your standing meeting on each transition.
FAQ
What's the best time for a meeting between Tokyo and Seoul?

Can I schedule a daily standup that works for both Tokyo and Seoul?
