What time is it in Rui'an right now?

The time in Rui'an, China is 8:27 pm, 20:27 on a 24 hour clock, on Sunday September 27, 2026. The reading above ticks from your own device against the Asia/Shanghai rules, so it stays right through a clock change rather than drifting an hour out twice a year.

Rui'an sits at 27.78 degrees north and 120.66 degrees east, just outside the tropics and 3,089 km from the equator. Its clock is set to a zone whose nominal meridian is 120.0 degrees east, and the city itself is 0.7 degrees east of that line. Those 0.7 degrees are worth 2 minutes 38 seconds of sun time, which is most of why solar noon here lands at 11:48 am rather than on the stroke of twelve.

Rui'an time zone and UTC offset

The IANA zone for Rui'an, China is Asia/Shanghai. Right now it is running at UTC+8 and the abbreviation in force is CST. Rui'an does not change its clocks at any point in the year. The offset stays at UTC+8 in January and in July alike, so no conversion involving Rui'an ever needs a seasonal footnote.

Where Rui'an is on the map

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 Rui'an 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 Rui'an.

Best time to call Rui'an

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/Shanghai time

684 of our cities keep Asia/Shanghai, so every one of them reads 8:27 pm at this moment and changes its clocks on the same night as Rui'an. Nearest first:

Moon phase over Rui'an tonight

The moon is a waning gibbous tonight, 16.4 days into its cycle and about 97% lit. The next full moon falls on October 26, 2026 at 12:11 pm Shanghai time, and the next new moon on October 10, 2026 at 11:49 pm. Both are the same instant everywhere on Earth, printed here on the Rui'an clock, which is why the calendar date can differ from the one a reader further east or west sees.

When the clocks change in Rui'an

There is no clock change scheduled in Asia/Shanghai within the next 400 days, so Rui'an stays at UTC+8 for the whole of that stretch.

That makes Rui'an 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 Rui'an is from other cities

Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to Rui'an is Wenzhou, China at 25 km, and the furthest is Resistencia, Argentina at 19,966 km, which is 100% of the way to being exactly opposite.

The antipode of Rui'an

Dig straight through the centre of the Earth from Rui'an, China and you come out at 27.78 degrees south, 59.34 degrees west. That point is near Resistencia, Argentina. The nearest city in our catalogue to it is Resistencia, Argentina, 49 km away from the antipode itself, where the clock currently reads 9:27 am on Sunday.

The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 27.78 degrees north becomes 27.78 degrees south, and 120.66 degrees east becomes 59.34 degrees west. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: Rui'an is one of the exceptions, with dry land on the far side. The local time at the antipode runs close to UTC-4, roughly twelve hours from Rui'an, because a half turn of longitude is a half turn of the day.

Sunrise and sunset in Rui'an

Today the sun rises in Rui'an at 5:48 am and sets at 5:49 pm, giving 12 hours 1 minute 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 Rui'an.

Sun and moon in Rui'an today

The sun is up in Rui'an for 12 hours 1 minute today, from 5:48 am to 5:49 pm. The moon sets in Rui'an at 6:05 am and comes up again at 5:58 pm. The next phase is the last quarter on October 3, 2026. The moon is full, or as near to it as makes no difference, and the whole of the face turned towards us is lit.

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 Rui'an

Seven days from September 27, 2026, computed for Rui'an, China at 27.78 degrees north, 120.66 degrees east, on the clock of Asia/Shanghai. 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 Rui'an, China, 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 Rui'an

From Rui'an, China the qibla is 285.5 degrees on a true compass, which is west-northwest, or 15.5 degrees south of due west. The Kaaba is 8,057 km away, 5,006 miles, measured over the surface of the Earth.

That figure is the initial bearing of the great circle from Rui'an, China 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 Rui'an, China 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.
