About
Working across 13 hours of time difference
With 13 hours between Seoul and New York City, there is essentially no overlap during normal business hours. One side will always be early-morning or late-evening. Async-first collaboration is the realistic default. Reserve live calls for genuinely high-bandwidth conversations and rotate who absorbs the inconvenience week-to-week.
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 Seoul and New York City 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 Seoul and New York City?
Best overlap: 9:00 AM–9:00 AM Seoul time (1/2 zones in business hours). The strongest business-hour overlap is UTC 0:00–1:00, which is Seoul 9:00 AM–9:00 AM and New York City 8:00 PM–8:00 PM locally.
What is the time difference between Seoul and New York City?
Seoul is currently UTC+09:00 and New York City is UTC-04:00, a difference of 13 hours. The exact gap can shift by one hour when one city switches to or from Daylight Saving Time.
Should we shift the meeting if one city changes Daylight Saving Time?
Yes — when only one of the two cities observes DST, the overlap window moves by an hour. Re-check this page in the weeks around March/April and October/November and adjust your standing meeting accordingly. The 24-hour grid below always reflects the current correct offset.
Can I schedule a daily standup that works for both Seoul and New York City?
Probably not as a daily — the offset is too large for both sides to stay in standard hours. Consider an asynchronous standup (written updates) and reserving live meetings for weekly or fortnightly cadence.
