What time is it in Castelar right now?

The time in Castelar, Argentina is 1:59 pm, 13:59 on a 24 hour clock, on Saturday September 26, 2026. The reading above ticks from your own device against the America/Argentina/Buenos_Aires rules, so it stays right through a clock change rather than drifting an hour out twice a year.

Castelar sits at 34.65 degrees south and 58.64 degrees west, in the subtropical belt and 3,853 km from the equator. Its clock is set to a zone whose nominal meridian is 45.0 degrees west, and the city itself is 13.6 degrees west of that line. Those 13.6 degrees are worth 54 minutes 34 seconds of sun time, which is most of why solar noon here lands at 12:46 pm rather than on the stroke of twelve.

Moon phase over Castelar tonight

The moon is a waning gibbous tonight, 15.6 days into its cycle and about 99% lit. The next full moon falls on October 26, 2026 at 1:11 am Buenos Aires time, and the next new moon on October 10, 2026 at 12:49 pm. Both are the same instant everywhere on Earth, printed here on the Castelar clock, which is why the calendar date can differ from the one a reader further east or west sees.

There is no clock change scheduled in America/Argentina/Buenos_Aires within the next 400 days, so Castelar stays at UTC-3 for the whole of that stretch.

That makes Castelar 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 Castelar is from other cities

Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to Castelar is Isidro Casanova, Argentina at 7 km, and the furthest is Qingdao, China at 19,835 km, which is 99% of the way to being exactly opposite.

The antipode of Castelar

Dig straight through the centre of the Earth from Castelar, Argentina and you come out at 34.65 degrees north, 121.36 degrees east. That point is near Qingdao, China. The nearest city in our catalogue to it is Qingdao, China, 181 km away from the antipode itself, where the clock currently reads 12:59 am on Sunday.

The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 34.65 degrees south becomes 34.65 degrees north, and 58.64 degrees west becomes 121.36 degrees east. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: Castelar is one of the exceptions, with dry land on the far side. The local time at the antipode runs close to UTC+9, roughly twelve hours from Castelar, because a half turn of longitude is a half turn of the day.

Sunrise and sunset in Castelar

Today the sun rises in Castelar at 6:38 am and sets at 6:54 pm, giving 12 hours 16 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 Castelar.

Sun and moon in Castelar today

The sun is up in Castelar for 12 hours 16 minutes today, from 6:38 am to 6:54 pm. The moon sets in Castelar at 6:21 am and comes up again at 7:07 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 Castelar

Seven days from September 26, 2026, computed for Castelar, Argentina at 34.65 degrees south, 58.64 degrees west, on the clock of America/Argentina/Buenos_Aires. 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 Castelar, Argentina, 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 Castelar

From Castelar, Argentina the qibla is 76.4 degrees on a true compass, which is east-northeast, or 13.6 degrees north of due east. The Kaaba is 12,086 km away, 7,510 miles, measured over the surface of the Earth.

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