What time is it in South Korea?

South Korea stays on UTC+9:00 all year. Its offset from UTC never moves, so its relationship to places that do change shifts twice a year instead — which is usually why someone checks. Right now it is 9 hours ahead of UTC, and 14 hours ahead of New York.

Seoul is 14 hours ahead of New York and 17 hours ahead of Los Angeles. 9am in New York is 11:00 pm in Seoul.

To convert a specific time rather than read the current one, the converter shows both directions with the next clock change for each.

The day is 10 hours 14 minutes long in Seoul, and losing 2 minutes a day. The sun peaks at 12:16 pm, 16 minutes after noon on the clock. A UTC offset is a promise that the sun is overhead at midday on one meridian, and Seoul sits 32 minutes of solar time west of UTC+9:00’s. The rest is the equation of time, which swings about a quarter of an hour either way across the year.

The solar year swings 5 hours 12 minutes in Seoul: 14 hours 45 minutes of daylight at the June solstice against 9 hours 34 minutes at the December one. Being north of the equator, its longest day falls in June — the opposite way round from the other hemisphere.

South Korea has kept UTC+9:00 since Sunday, October 9, 1988, when it moved from UTC+10:00. Before that its clocks read 1 hour ahead of what they read now.

On UTC+9:00 right now, the same clock as South Korea:
