Suwon in Gyeonggi-do keeps Korea Standard Time, UTC+9, all year. The live clock is the city’s civil hour, with sunrise, sunset, and peninsula weather. Suwon is the provincial capital of Gyeonggi, south of Seoul, not a private fortress hour and not a second Korean zone. Official clocks follow Korea Standard Time: nine hours ahead of UTC, matching Seoul, Busan, and Jeju at every instant. A stated time here is the same numerals as in the capital. The light over Hwaseong and the light over the Han are not the same table.
Software usually files the country under Asia/Seoul. That identifier is the one to pick even when the meeting is in Suwon. The label names the national zone file, not a requirement to use Seoul’s sunrise. If a form offers “Korea” or “KST,” that is this offset. Leave daylight saving off. South Korea does not currently spring clocks forward.
Japan also keeps UTC+9, so a call toward Osaka needs no arithmetic for the hour. China is UTC+8, so a call toward Shanghai is one hour, not zero. People who treat “East Asia” as a single clock find that gap in the first meeting. North Korea currently uses the same offset as well under present rules; still name the city, because older notes have described other arrangements.
A ride from Suwon toward Seoul does not change the watch. It costs travel time. School bells, broadcasts, and office diaries are printed on KST unless a notice says otherwise. Set the zone to Asia/Seoul or to Korea Standard Time, then pick Suwon for the sky.
UTC+9 is built on 135°E. Suwon lies west of that meridian, so solar noon comes after 12:00 KST. Office lunch at noon is a civil custom. Highest sun arrives after that printed noon. Broadcasting and school bells follow the civil custom. Walkers on the fortress wall may follow the sun. The page gives you both.
Civil time: Korea Standard Time, UTC+9, nationwide. Computer name: Asia/Seoul — a national file, not a capital-only clock. Daylight saving: not used in present South Korean civil time. Place check: Suwon, Gyeonggi-do, south of Seoul, not a namesake elsewhere.
KST is less ambiguous than CST, but “Korea time” on a mixed invite can still be read as a Seoul-only habit. Write “Suwon (UTC+9)” when the audience is mixed. A weekly call booked as 09:00 here stays 09:00 against UTC in every month. If a partner in the United States springs forward, their local equivalent twitches. Suwon’s wall does not.
Sunrise and sunset on this page are calculated for Suwon’s latitude and longitude on the date you are viewing. The figures are rebuilt for the day you are viewing. Hills, haze, and monsoon cloud can hide the disk after the listed rising. The figure is an astronomical event at an ideal horizon, not a promise of a clear rim over the fortress.
Because Suwon sits well north of the equator, June and December are different lengths of light. Summer evenings stretch. Winter afternoons shorten. None of that is a clock change. Small daily drifts become the wrong month if you paste.
Do not paste a Seoul sunrise onto this block as a shortcut, even though the urban region is shared. Do not paste a Busan sunrise because both cities share KST. For a dawn start in Suwon, use Suwon’s figures. Seoul’s hour is Suwon’s hour. Seoul’s Han sunrise is still the wrong table for this wall.
Suwon has a real winter and a real summer, a spring people wait for, and an autumn people photograph. A summer monsoon stretch brings humid air and rain. None of that is a time zone. The offset does not bloom. Four seasons are a year. The panel is this afternoon.
A January commute can start in the dark on a clock that already says morning. Monsoon humidity is weather. It is not an extra hour. Neither pattern moves UTC+9. Rain can stall a road and leave KST untouched.
If you will actually stand in Suwon, use this forecast, not a Seoul tab copied from another basin street and not a Tokyo tab that happens to show the same numerals. Clothes follow the weather column. Meetings follow KST. Say 2 p.m. in Suwon and let the other side convert.
