Current time in Seongnam-si, South Korea right now
It is 2:22 am in Seongnam-si, South Korea 🇰🇷 right now, on Monday, September 28, 2026. The city keeps Asia/Seoul, which is KST at UTC+9, so Seongnam-si is 9 hours ahead of UTC, where it is 5:22 pm. The sun rose in Seongnam-si at 6:24 am and sets at 6:20 pm, which is 11 hours 56 minutes of daylight.
What time is it in Seongnam-si right now?
The time in Seongnam-si, South Korea is 2:22 am, 02:22 on a 24 hour clock, on Monday September 28, 2026. The reading above ticks from your own device against the Asia/Seoul rules, so it stays right through a clock change rather than drifting an hour out twice a year.
Seongnam-si sits at 37.44 degrees north and 127.14 degrees east, in the subtropical belt and 4,163 km from the equator. Its clock is set to a zone whose nominal meridian is 135.0 degrees east, and the city itself is 7.9 degrees west of that line. Those 7.9 degrees are worth 31 minutes 27 seconds of sun time, which is most of why solar noon here lands at 12:22 pm rather than on the stroke of twelve.
Seongnam-si time zone and UTC offset
The IANA zone for Seongnam-si, South Korea is Asia/Seoul. Right now it is running at UTC+9 and the abbreviation in force is KST. Seongnam-si does not change its clocks at any point in the year. The offset stays at UTC+9 in January and in July alike, so no conversion involving Seongnam-si ever needs a seasonal footnote.

Moon phase over Seongnam-si tonight
The moon is a waning gibbous tonight, 16.6 days into its cycle and about 96% lit. The next full moon falls on October 26, 2026 at 1:11 pm Seoul time, and the next new moon on October 11, 2026 at 12:49 am. Both are the same instant everywhere on Earth, printed here on the Seongnam-si clock, which is why the calendar date can differ from the one a reader further east or west sees.
When the clocks change in Seongnam-si
There is no clock change scheduled in Asia/Seoul within the next 400 days, so Seongnam-si stays at UTC+9 for the whole of that stretch.
That makes Seongnam-si an easy city to schedule against: a meeting fixed at a given hour here holds its relationship to UTC all year, and only the other end of the call can move.
How far Seongnam-si is from other cities
Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to Seongnam-si is Hanam, South Korea at 13 km, and the furthest is Maldonado, Uruguay at 19,676 km, which is 98% of the way to being exactly opposite.

The antipode of Seongnam-si
Dig straight through the centre of the Earth from Seongnam-si, South Korea and you come out at 37.44 degrees south, 52.86 degrees west. That point is near Maldonado, Uruguay. The nearest city in our catalogue to it is Maldonado, Uruguay, 339 km away from the antipode itself, where the clock currently reads 2:22 pm on Sunday.
The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 37.44 degrees north becomes 37.44 degrees south, and 127.14 degrees east becomes 52.86 degrees west. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: Seongnam-si is one of the exceptions, with dry land on the far side. The local time at the antipode runs close to UTC-3, roughly twelve hours from Seongnam-si, because a half turn of longitude is a half turn of the day.
Sunrise and sunset in Seongnam-si
Today the sun rises in Seongnam-si at 6:24 am and sets at 6:20 pm, giving 11 hours 56 minutes of daylight. The dedicated page for this city carries the month by month table, the longest and shortest days of 2026, the golden and blue hour bands at both ends of the day, and all three twilight stages: sunrise and sunset times in Seongnam-si.

Sun and moon in Seongnam-si today
The sun is up in Seongnam-si for 11 hours 56 minutes today, from 6:24 am to 6:20 pm. The moon sets in Seongnam-si at 7:52 am and comes up again at 6:52 pm. The next phase is the last quarter on October 3, 2026. It is 97% lit at the moment, a waning gibbous, thinning by about 3.4 percentage points a day.
| Sun | Time in Seongnam-si |
|---|---|
| Astronomical dawn | 4:57 am |
| Nautical dawn | 5:28 am |
| Civil dawn | 5:58 am |
| Sunrise | 6:24 am |
| Solar noon | 12:22 pm |
| Sunset | 6:20 pm |
| Civil dusk | 6:46 pm |
| Nautical dusk | 7:16 pm |
| Astronomical dusk | 7:47 pm |
Twilight is graded by how far the sun has dropped below the horizon. Civil twilight ends six degrees down, which is roughly the point at which you need a light to read outside. Nautical twilight ends at twelve degrees, when the horizon at sea stops being usable for a sextant sight. Astronomical twilight ends at eighteen degrees, which is full darkness for an observer.
| Light band | Time in Seongnam-si | Length |
|---|---|---|
| Morning blue hour | 5:58 am to 6:08 am | 0h 10m |
| Morning golden hour | 6:08 am to 6:59 am | 0h 51m |
| Evening golden hour | 5:45 pm to 6:36 pm | 0h 50m |
| Evening blue hour | 6:36 pm to 6:46 pm | 0h 10m |
Golden hour is the stretch with the sun between six degrees above the horizon and four below it, and blue hour runs from there down to six degrees below. Neither is literally an hour: each is as long as the sun takes to cross those few degrees, which is minutes near the equator and can be most of the evening at high latitude.
| Moon | Reading in Seongnam-si |
|---|---|
| Moonrise | 6:52 pm |
| Moonset | 7:52 am |
| Phase | waning gibbous, waning |
| Illumination | 97% of the disc lit |
| Moon age | 17.0 days since the new moon |
| Distance | 374,500 km |
Moonrise and moonset are computed to the moment the moon's upper edge touches a flat horizon, allowing for refraction, for the size of the disc and for the moon's parallax, which together put the centre of the moon at 0.125 degrees above the horizon at the instant it rises. That is a different horizon from the one sunrise uses, and it is why a moonrise time cannot be worked out with a sunrise formula.
Meeting planner: Seongnam-si and four other places

No hour on Monday, September 28, 2026 is inside 9 to 5 in all 5 places, so nothing is highlighted as a shared working hour. Seongnam-si and Los Angeles are 16 hours apart, which is more than the eight hour working day leaves room for. The closest is 2 of 5: from 12:00 am in Seongnam-si it is working hours in New York and London, but outside them in Seongnam-si, Los Angeles and Delhi. A meeting across this set has to be early or late for somebody.
Prayer times in Seongnam-si
Seven days from September 28, 2026, computed for Seongnam-si, South Korea at 37.44 degrees north, 127.14 degrees east, on the clock of Asia/Seoul. The method is Muslim World League (Muslim World League, Mecca), which puts Fajr at 18.0 degrees below the horizon and Isha at 17.0 degrees. Asr uses the Standard shadow ratio of 1, which is the Shafi'i, Maliki and Hanbali position.

| Sunday October 4 | 5:02 am | 6:29 am | 12:20 pm | 3:39 pm | 6:11 pm | 7:32 pm |
Dhuhr is solar noon at Seongnam-si, South Korea, the instant the Sun crosses the local meridian, so it moves with longitude inside the time zone and with the equation of time through the year rather than sitting at a fixed clock reading. Sunrise and Maghrib are the standard refracted horizon, the same 0.833 degrees every almanac uses. Every figure above is computed from the Sun's position for this exact coordinate; none of it is copied from a table.
Different methods disagree, and that is expected rather than an error. Fajr under ISNA at 15 degrees comes later than Fajr under Egyptian General Authority of Survey at 19.5 degrees, by twenty minutes or more depending on latitude and season. Follow whichever your local mosque follows.
Qibla direction from Seongnam-si
From Seongnam-si, South Korea the qibla is 285.8 degrees on a true compass, which is west-northwest, or 15.8 degrees south of due west. The Kaaba is 8,354 km away, 5,191 miles, measured over the surface of the Earth.
That figure is the initial bearing of the great circle from Seongnam-si, South Korea to 21.4225 degrees north, 39.8262 degrees east, which is the Kaaba inside Masjid al-Haram.
The bearing is measured from true north, not magnetic north. A magnetic compass points at the magnetic pole, and the difference between the two can be anything from nothing to more than twenty degrees depending where you are, so check your compass reading against magnetic declination for Seongnam-si, South Korea before you use it. A phone compass set to true north, or the shadow of a vertical stick at local solar noon, avoids the problem entirely.
Put a Seongnam-si clock on your site
A live clock showing the current time in Seongnam-si, South Korea, ready to paste into any page that accepts HTML. It reads Asia/Seoul from the time zone database, so it stays right when Seongnam-si changes its clocks, and it shows KST to every visitor wherever they are reading from. It is a plain iframe: no account, no script to install, nothing to pay.
The box needs 183 pixels of height for these settings, which is what the code above sets, and the numbers show at full size from 305 pixels of width up. Narrower than that they scale down rather than wrapping, and turning a line off makes the box shorter. The code updates with either.
