Current time in San Luis, Argentina right now
It is 3:52 pm in San Luis, Argentina 🇦🇷 right now, on Sunday, September 27, 2026. The city keeps America/Argentina/San_Luis, which is UTC-3 at UTC-3, so San Luis is 3 hours behind of UTC, where it is 6:52 pm. The sun rose in San Luis at 7:08 am and sets at 7:25 pm, which is 12 hours 17 minutes of daylight.
What time is it in San Luis right now?
The time in San Luis, Argentina is 3:52 pm, 15:52 on a 24 hour clock, on Sunday September 27, 2026. The reading above ticks from your own device against the America/Argentina/San_Luis rules, so it stays right through a clock change rather than drifting an hour out twice a year.
San Luis sits at 33.29 degrees south and 66.32 degrees west, in the subtropical belt and 3,702 km from the equator. Its clock is set to a zone whose nominal meridian is 45.0 degrees west, and the city itself is 21.3 degrees west of that line. Those 21.3 degrees are worth 85 minutes 18 seconds of sun time, which is most of why solar noon here lands at 1:16 pm rather than on the stroke of twelve.
San Luis time zone and UTC offset
The IANA zone for San Luis, Argentina is America/Argentina/San_Luis. Right now it is running at UTC-3 and the abbreviation in force is UTC-3. San Luis does not change its clocks at any point in the year. The offset stays at UTC-3 in January and in July alike, so no conversion involving San Luis ever needs a seasonal footnote.

Cities on America/Argentina/San_Luis time
San Luis is the only city in our catalogue on America/Argentina/San_Luis. Other cities may share its UTC-3 offset today without sharing its rules, which is the distinction that matters the moment a clock change comes round.
Moon phase over San Luis tonight
The moon is a waning gibbous tonight, 16.6 days into its cycle and about 96% lit. The next full moon falls on October 26, 2026 at 1:11 am San Luis 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 San Luis clock, which is why the calendar date can differ from the one a reader further east or west sees.
When the clocks change in San Luis
There is no clock change scheduled in America/Argentina/San_Luis within the next 400 days, so San Luis stays at UTC-3 for the whole of that stretch.
That makes San Luis 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 San Luis is from other cities
Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to San Luis is Rio Cuarto, Argentina at 184 km, and the furthest is Luohe, China at 19,969 km, which is 100% of the way to being exactly opposite.

The antipode of San Luis
Dig straight through the centre of the Earth from San Luis, Argentina and you come out at 33.29 degrees north, 113.68 degrees east. That point is near Luohe, China. The nearest city in our catalogue to it is Luohe, China, 46 km away from the antipode itself, where the clock currently reads 2:52 am on Monday.
The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 33.29 degrees south becomes 33.29 degrees north, and 66.32 degrees west becomes 113.68 degrees east. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: San Luis 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 San Luis, because a half turn of longitude is a half turn of the day.
Sunrise and sunset in San Luis
Today the sun rises in San Luis at 7:08 am and sets at 7:25 pm, giving 12 hours 17 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 San Luis.

Sun and moon in San Luis today
The sun is up in San Luis for 12 hours 17 minutes today, from 7:08 am to 7:25 pm. The moon sets in San Luis at 7:21 am and comes up again at 8:44 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.
| Sun | Time in San Luis |
|---|---|
| Astronomical dawn | 5:45 am |
| Nautical dawn | 6:14 am |
| Civil dawn | 6:43 am |
| Sunrise | 7:08 am |
| Solar noon | 1:16 pm |
| Sunset | 7:25 pm |
| Civil dusk | 7:50 pm |
| Nautical dusk | 8:19 pm |
| Astronomical dusk | 8:48 pm |
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.
| Light band | Time in San Luis | Length |
|---|---|---|
| Morning blue hour | 6:43 am to 6:53 am | 0h 10m |
| Morning golden hour | 6:53 am to 7:40 am | 0h 48m |
| Evening golden hour | 6:52 pm to 7:40 pm | 0h 48m |
| Evening blue hour | 7:40 pm to 7:50 pm | 0h 10m |
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.
| Moon | Reading in San Luis |
|---|---|
| Moonrise | 8:44 pm |
| Moonset | 7:21 am |
| Phase | waning gibbous, waning |
| Illumination | 99% of the disc lit |
| Moon age | 16.5 days since the new moon |
| Distance | 376,100 km |
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.

No hour on Sunday, September 27, 2026 is inside 9 to 5 in all 5 places, so nothing is highlighted as a shared working hour. Los Angeles and Delhi are 12 hours 30 minutes apart, which is more than the eight hour working day leaves room for. The closest is 3 of 5: from 10:00 am in San Luis it is working hours in San Luis, New York and London, but outside them in Los Angeles and Delhi. A meeting across this set has to be early or late for somebody.
Prayer times in San Luis
Seven days from September 27, 2026, computed for San Luis, Argentina at 33.29 degrees south, 66.32 degrees west, on the clock of America/Argentina/San_Luis. 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.
| Date | Fajr | Sunrise | Dhuhr | Asr | Maghrib | Isha |
|---|---|---|---|---|---|---|
| Sunday September 27 | 5:45 am | 7:08 am | 1:16 pm | 4:46 pm | 7:25 pm | 8:44 pm |

Dhuhr is solar noon at San Luis, 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 San Luis
From San Luis, Argentina the qibla is 79.7 degrees on a true compass, which is east, or 10.3 degrees north of due east. The Kaaba is 12,748 km away, 7,921 miles, measured over the surface of the Earth.
That figure is the initial bearing of the great circle from San Luis, 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 San Luis, 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.
