8 AM Eastern to Seoul: what to know
Seoul is 14 hours ahead of New York during EST, narrowing to 13 hours during US daylight saving (EDT). At 8 AM New York, Seoul is at 10 PM (winter) or 9 PM (summer) — both late in the evening for Korean colleagues. This is among the more manageable US–Korea windows compared to later ET hours that push Seoul past midnight.
Teams with recurring US–Korea calls often rotate the burden: one week the US side takes an early-morning slot, the next week the Korean side accepts a late evening call. Use the New York to Seoul planner to see the overlap window for today's date, or the Meeting Time Finder to build a custom schedule.
