It is 9:47 am in Chu, Vietnam 🇻🇳 right now, on Sunday, September 27, 2026. The city keeps Asia/Bangkok, which is UTC+7 at UTC+7, so Chu is 7 hours ahead of UTC, where it is 2:47 am. The sun rose in Chu at 5:44 am and sets at 5:46 pm, which is 12 hours 2 minutes of daylight.

What time is it in Chu right now?

The time in Chu, Vietnam is 9:47 am, 09:47 on a 24 hour clock, on Sunday September 27, 2026. The reading above ticks from your own device against the Asia/Bangkok rules, so it stays right through a clock change rather than drifting an hour out twice a year.

Chu sits at 21.37 degrees north and 106.57 degrees east, inside the tropics, north of the equator and 2,377 km from the equator. Its clock is set to a zone whose nominal meridian is 105.0 degrees east, and the city itself is 1.6 degrees east of that line. Those 1.6 degrees are worth 6 minutes 16 seconds of sun time, which is most of why solar noon here lands at 11:45 am rather than on the stroke of twelve.

Chu time zone and UTC offset

The IANA zone for Chu, Vietnam is Asia/Bangkok. Right now it is running at UTC+7 and the abbreviation in force is UTC+7. Chu does not change its clocks at any point in the year. The offset stays at UTC+7 in January and in July alike, so no conversion involving Chu ever needs a seasonal footnote.

Daylight hours in Chu today

The sun rose in Chu at 5:44 am and sets at 5:46 pm, which is 12 hours 2 minutes of daylight. Solar noon, the instant the sun stands at its highest over Chu, is at 11:45 am, which is 15 minutes before clock noon. The sun's declination today is -1.63 degrees, so at this latitude it reaches about 67.0 degrees above the horizon at its highest, to the south.

The full month by month picture for this city, the extremes of the year and every twilight band are on the sunrise and sunset page for Chu, which works from the same coordinates.

Where Chu 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 Chu 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 Chu.

Best time to call Chu

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/Bangkok time

105 of our cities keep Asia/Bangkok, so every one of them reads 9:47 am at this moment and changes its clocks on the same night as Chu. Nearest first:

Moon phase over Chu tonight

The moon is a waning gibbous tonight, 16.0 days into its cycle and about 98% lit. The next full moon falls on October 26, 2026 at 11:11 am Bangkok time, and the next new moon on October 10, 2026 at 10:49 pm. Both are the same instant everywhere on Earth, printed here on the Chu clock, which is why the calendar date can differ from the one a reader further east or west sees.

When the clocks change in Chu

There is no clock change scheduled in Asia/Bangkok within the next 400 days, so Chu stays at UTC+7 for the whole of that stretch.

That makes Chu 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 Chu is from other cities

Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to Chu is Thi Tran GJong Trieu, Vietnam at 33 km, and the furthest is Iquique, Chile at 19,650 km, which is 98% of the way to being exactly opposite.

The antipode of Chu

Dig straight through the centre of the Earth from Chu, Vietnam and you come out at 21.37 degrees south, 73.43 degrees west. That point is near Iquique, Chile. The nearest city in our catalogue to it is Iquique, Chile, 365 km away from the antipode itself, where the clock currently reads 11:47 pm on Saturday.

The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 21.37 degrees north becomes 21.37 degrees south, and 106.57 degrees east becomes 73.43 degrees west. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: Chu is one of the exceptions, with dry land on the far side. The local time at the antipode runs close to UTC-5, roughly twelve hours from Chu, because a half turn of longitude is a half turn of the day.

Sunrise and sunset in Chu

Today the sun rises in Chu at 5:44 am and sets at 5:46 pm, giving 12 hours 2 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 Chu.

Sun and moon in Chu today

The sun is up in Chu for 12 hours 2 minutes today, from 5:44 am to 5:46 pm. The moon sets in Chu at 6:00 am and comes up again at 6:01 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 Chu

Seven days from September 27, 2026, computed for Chu, Vietnam at 21.37 degrees north, 106.57 degrees east, on the clock of Asia/Bangkok. 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 Chu, Vietnam, 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 Chu

From Chu, Vietnam the qibla is 283.6 degrees on a true compass, which is west-northwest, or 13.6 degrees south of due west. The Kaaba is 6,851 km away, 4,257 miles, measured over the surface of the Earth.

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