Current Time in Seoul

About time in Seoul

Seoul runs on Korea Standard Time, a steady UTC+9 with no seasonal changes. South Korea experimented with daylight saving decades ago but has not used it in modern times, so the clocks here stay fixed year-round. Seoul shares its UTC+9 offset with Tokyo, which makes scheduling across Korea and Japan refreshingly simple. With its dense metropolitan area home to roughly 26 million people, the capital keeps the same time whether it is the depths of winter or the height of summer.

Seoul does not make seasonal clock changes under its current rules. Its offset is UTC+9 (no DST). The live clock above reads Seoul's local time directly from the IANA time zone database in your browser, using the rules installed on your device.

Daylight in Seoul through 2026

Seoul sits at about 37.6°N, 127.0°E. The longest day of 2026 is June 20, with 14h 46m between sunrise and sunset. The shortest is December 18, with 9h 34m, a difference of 5 h 12 min. At this mid-latitude, winter evenings are dark early and summer evenings stay light well after a normal working day.

The earliest sunrise of the year comes around June 8 (05:10) and the latest sunset around June 24 (19:57). These are not exactly on the solstice because the sun’s position runs slightly ahead of or behind clock time during the year.

Solar noon, when the sun is highest, falls at about 12:39 local time in late March, 12:33 in late June and 12:29 in late December. In standard time the sun is highest at about 12:32 on average, about 32 minutes after 12:00, a modest gap between clock and sun time in Seoul.
