It is 9:07 pm in Asia/Seoul

Asia/Seoul is the IANA identifier for the time zone of Seoul in South Korea. It is running at UTC+9 right now, abbreviated KST, and the local date is Saturday, September 26, 2026. The zone never moves its clocks.

What time is it in Asia/Seoul right now

9:07 pm on Saturday, September 26, 2026, as this page was served, which in 24 hour form is 21:07. The clock above ticks on from there in your own browser. The offset is a whole 9 hours ahead of UTC, so a UTC timestamp converts here by changing the hour and leaving the minutes exactly as they are.

8 other zones read UTC+9 at this instant. They are interchangeable as a clock reading today and not as an identifier: storing UTC+9 instead of Asia/Seoul throws away the rule that decides what they all do at the next transition.

The UTC offset of Asia/Seoul

An offset of UTC+9 names the meridian 135.0 degrees east. Seoul, South Korea actually sits at 126.98 degrees east, which is 8.0 degrees west of it, so the sun there runs about 32 minutes behind the clock before daylight saving is even considered. Zone boundaries are drawn by borders and by convenience, not by longitude, and this is the size of the gap that produces.

Because this zone never moves its clocks, UTC+9 is the answer on every day of the year. That makes it an easy zone to schedule against, with the caveat that the other end of the call may still be moving its own clocks, so the gap between the two changes even though nothing changed here.

Daylight saving in Asia/Seoul

Asia/Seoul does not observe daylight saving. It sits at UTC+9 in January and reads UTC+9 again in July, so a gap worked out against it today is still right in six months. It did move them once: the sampling below shows a summer offset as late as 1988, and the practice has since been dropped.

The database holds no clock change for Asia/Seoul in 2025, 2026 or 2027, so there is no transition table to print. The offset shown at the top of this page is the offset on every date in those three years.

How the offset of Asia/Seoul has changed since 1970

Read on 1 January and 1 July of each year, which is the cheapest pair of samples that shows both the winter offset and whether the clocks moved that summer. The zone has passed through 3 distinct eras in that time and has used 2 different offsets: UTC+9, UTC+10. Its current behaviour has held since 1989. A rule change that began and ended between July and the following January is invisible to this sampling, so the table is a shape rather than a complete edit history.

The last summer in which Asia/Seoul read a different offset from its own January was 1988. Software that still carries a hand-written summer rule for this zone has been wrong every year since.

Cities in the Asia/Seoul time zone

The 59 cities this site covers inside Asia/Seoul, each with a live clock and today's sunrise and sunset worked out from its own coordinate. They share an identifier, so they share a clock reading to the minute, and they do not share a sunrise: that is set by latitude and longitude.

The sun against the clock in Asia/Seoul

Worked out for Seoul, South Korea, the city this site covers inside the zone, at 37.57 degrees north, 126.98 degrees east. The sun rises at 6:23 am and sets at 6:24 pm, giving 12 hours 1 minute of daylight. Solar noon, the moment the sun is highest, falls at 12:24 pm, which is 24 minutes after clock noon.

That gap is the whole argument about where zone lines belong, in one number. It is made of three things: Seoul, South Korea sitting 8.0 degrees west of the UTC+9 meridian, the equation of time, which today runs 8.5 minutes ahead of mean time, and no daylight saving at all, because this zone does not use it. Full sunrise and sunset times for Seoul.

South Korea.

Why store Asia/Seoul instead of UTC+9?

Because the offset is an output and the identifier is the input. This zone has one offset today and no guarantee of keeping it, and 8 other zones share its current reading while carrying different rules. A record storing UTC+9 cannot tell them apart; a record storing Asia/Seoul keeps working through every future rule change.
