What time is it in Constantine right now?

The time in Constantine, Algeria is 4:02 pm, 16:02 on a 24 hour clock, on Saturday September 26, 2026. The reading above ticks from your own device against the Africa/Algiers rules, so it stays right through a clock change rather than drifting an hour out twice a year.

Constantine sits at 36.37 degrees north and 6.61 degrees east, in the subtropical belt and 4,044 km from the equator. Its clock is set to a zone whose nominal meridian is 15.0 degrees east, and the city itself is 8.4 degrees west of that line. Those 8.4 degrees are worth 33 minutes 32 seconds of sun time, which is most of why solar noon here lands at 12:25 pm rather than on the stroke of twelve.

Where Constantine 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 Constantine 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 Constantine.

Best time to call Constantine

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 Africa/Algiers time

42 of our cities keep Africa/Algiers, so every one of them reads 4:02 pm at this moment and changes its clocks on the same night as Constantine. Nearest first:

Moon phase over Constantine tonight

The moon is a waning gibbous tonight, 15.5 days into its cycle and about 99% lit. The next full moon falls on September 26, 2026 at 5:48 pm Algiers time, and the next new moon on October 10, 2026 at 4:49 pm. Both are the same instant everywhere on Earth, printed here on the Constantine clock, which is why the calendar date can differ from the one a reader further east or west sees.

When the clocks change in Constantine

There is no clock change scheduled in Africa/Algiers within the next 400 days, so Constantine stays at UTC+1 for the whole of that stretch.

That makes Constantine 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 Constantine is from other cities

Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to Constantine is Skikda, Algeria at 63 km, and the furthest is Tauranga, New Zealand at 19,077 km, which is 95% of the way to being exactly opposite.

The antipode of Constantine

Dig straight through the centre of the Earth from Constantine, Algeria and you come out at 36.37 degrees south, 173.39 degrees west. That point is near Tauranga, New Zealand. The nearest city in our catalogue to it is Tauranga, New Zealand, 939 km away from the antipode itself, where the clock currently reads 4:02 am on Sunday.

The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 36.37 degrees north becomes 36.37 degrees south, and 6.61 degrees east becomes 173.39 degrees west. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: Constantine is one of the exceptions, with dry land on the far side. The local time at the antipode runs close to UTC-11, roughly twelve hours from Constantine, because a half turn of longitude is a half turn of the day.

Sunrise and sunset in Constantine

Today the sun rises in Constantine at 6:25 am and sets at 6:25 pm, giving 12 hours 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 Constantine.

Sun and moon in Constantine today

The sun is up in Constantine for 12 hours today, from 6:25 am to 6:25 pm. The moon sets in Constantine at 6:01 am and comes up again at 6:09 pm. The next phase is the full moon on September 26, 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 Constantine

Seven days from September 26, 2026, computed for Constantine, Algeria at 36.37 degrees north, 6.61 degrees east, on the clock of Africa/Algiers. 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 Constantine, Algeria, 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 Constantine

From Constantine, Algeria the qibla is 108.2 degrees on a true compass, which is east-southeast, or 18.2 degrees south of due east. The Kaaba is 3,610 km away, 2,243 miles, measured over the surface of the Earth.

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