What time is it in Siheungdong right now?

The time in Siheungdong, South Korea is 5:58 am, 05:58 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.

Siheungdong sits at 37.45 degrees north and 126.91 degrees east, in the subtropical belt and 4,164 km from the equator. Its clock is set to a zone whose nominal meridian is 135.0 degrees east, and the city itself is 8.1 degrees west of that line. Those 8.1 degrees are worth 32 minutes 21 seconds of sun time, which is most of why solar noon here lands at 12:23 pm rather than on the stroke of twelve.

Siheungdong time zone and UTC offset

The marker sits at the coordinates this whole page is computed from, so the sun times, the distances and the solar noon above all belong to this exact point rather than to the wider metropolitan area.

Time difference between Siheungdong and major cities

Every row below is computed at this instant, so daylight saving on either side is already in it. A positive figure means that city's clock reads later than Siheungdong.

Best time to call Siheungdong

Treating a working day as 9am to 6pm on both sides, this is the window the two cities genuinely share. Some of these pairs have no shared working hour at all, which is worth knowing before a meeting is proposed.

Cities on Asia/Seoul time

59 of our cities keep Asia/Seoul, so every one of them reads 5:58 am at this moment and changes its clocks on the same night as Siheungdong. Nearest first:

Moon phase over Siheungdong tonight

The moon is a waning gibbous tonight, 16.7 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 Siheungdong clock, which is why the calendar date can differ from the one a reader further east or west sees.

When the clocks change in Siheungdong

There is no clock change scheduled in Asia/Seoul within the next 400 days, so Siheungdong stays at UTC+9 for the whole of that stretch.

That makes Siheungdong 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 Siheungdong is from other cities

Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to Siheungdong is Gwangmyeong, South Korea at 5 km, and the furthest is Maldonado, Uruguay at 19,686 km, which is 98% of the way to being exactly opposite.

The antipode of Siheungdong

Dig straight through the centre of the Earth from Siheungdong, South Korea and you come out at 37.45 degrees south, 53.09 degrees west. That point is near Maldonado, Uruguay. The nearest city in our catalogue to it is Maldonado, Uruguay, 329 km away from the antipode itself, where the clock currently reads 5:58 pm on Sunday.

The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 37.45 degrees north becomes 37.45 degrees south, and 126.91 degrees east becomes 53.09 degrees west. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: Siheungdong 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 Siheungdong, because a half turn of longitude is a half turn of the day.

Sunrise and sunset in Siheungdong

Today the sun rises in Siheungdong at 6:25 am and sets at 6:21 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 Siheungdong.

Sun and moon in Siheungdong today

The sun is up in Siheungdong for 11 hours 56 minutes today, from 6:25 am to 6:21 pm. The moon sets in Siheungdong at 7:53 am and comes up again at 6:53 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.

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.

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.

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.

Prayer times in Siheungdong

Seven days from September 28, 2026, computed for Siheungdong, South Korea at 37.45 degrees north, 126.91 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.

Dhuhr is solar noon at Siheungdong, 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 Siheungdong

From Siheungdong, South Korea the qibla is 285.7 degrees on a true compass, which is west-northwest, or 15.7 degrees south of due west. The Kaaba is 8,334 km away, 5,178 miles, measured over the surface of the Earth.

That figure is the initial bearing of the great circle from Siheungdong, 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 Siheungdong, 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.
