When the difference changes
Eastern Time and Korea Standard Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – March 14, 2027Korea Standard Time is 14 hours ahead
- March 14, 2027 – November 7, 2027Korea Standard Time is 13 hours ahead
- November 7, 2027 – onwardsKorea Standard Time is 14 hours ahead
Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.
Daylight saving
Eastern Time
Clocks go forward one hour — 2:00 am becomes 3:00 am local time, and the zone is on EDT after that.
Korea Standard Time
Korea Standard Time stays on KST all year, so its offset from UTC never moves.

Scheduling between the two
There is no overlap between a nine-to-six working day in New York and one in Seoul — the gap is too wide. A call has to sit early or late for one side. Early morning in New York is the usual compromise, since that is late afternoon or evening in Seoul.
Eastern Time (EST) is used in Toronto, Atlanta, Miami, Detroit and most of the US east coast
