About time in Seoul
Seoul uses Korea Standard Time (KST, UTC+9) all year. Seoul does not use daylight saving time, so its UTC offset never changes.
South Korea uses one time zone, the same UTC+9 offset as Japan. It does not currently use daylight saving time.
South Korea uses Korea Standard Time, UTC+9, the same as Japan, and does not change its clocks. It has not always been so. From 1954 to 1961 the country used UTC+8:30, which matches the longitude of the peninsula more closely, before moving to UTC+9 in 1961.
Korea last used daylight saving time in 1987 and 1988, around the Seoul Olympics, and has not used it since. Because the offset is fixed, Seoul is 13 hours ahead of New York during American daylight saving time and 14 hours in winter, and 8 or 9 hours ahead of London. Calls with the United States usually take place in the Seoul morning, which is the previous evening in America. Seoul and Tokyo always show the same time.
