Korean schedule times in the Eastern zone
Korea is 14 hours ahead of New York in winter and 13 hours ahead in summer. 8:30 AM in Seoul is 6:30 PM the previous evening in New York in January and 7:30 PM in July. Enter a time or press Use now to see it on the Eastern clock.
Korea Standard Time is UTC+9 and does not change. New York does change, so the same KST announcement lands an hour earlier on the Eastern clock in summer. Fans following a release or a broadcast in KST need the date as much as the hour, since many results fall on the previous day.
Handoffs between the two cities need care. A handoff at 3:00 PM KST arrives at 1:00 AM Eastern in January and 2:00 AM in July, so nobody in New York sees it until the morning. A handoff late in the Seoul evening fits better: 9:00 PM KST is 7:00 AM Eastern in January. The hour-by-hour table lays a 9:00 to 17:00 Seoul day on the Eastern clock to show how little the days share.
Korea and Japan share the same offset, so a conversion from either gives the same Eastern time. Evening in Seoul is morning in New York: 11:00 PM KST is 9:00 AM Eastern in January. Press swap to read an Eastern time in Korea.
