What time is it in San Juan del Rio right now?

The time in San Juan del Rio, Mexico is 12:42 am, 00:42 on a 24 hour clock, on Sunday September 27, 2026. The reading above ticks from your own device against the America/Mexico_City rules, so it stays right through a clock change rather than drifting an hour out twice a year.

San Juan del Rio sits at 20.39 degrees north and 100.00 degrees west, inside the tropics, north of the equator and 2,267 km from the equator. Its clock is set to a zone whose nominal meridian is 90.0 degrees west, and the city itself is 10.0 degrees west of that line. Those 10.0 degrees are worth 39 minutes 59 seconds of sun time, which is most of why solar noon here lands at 12:31 pm rather than on the stroke of twelve.

Moon phase over San Juan del Rio tonight

The moon is a waning gibbous tonight, 16.1 days into its cycle and about 98% lit. The next full moon falls on October 25, 2026 at 10:11 pm Mexico City time, and the next new moon on October 10, 2026 at 9:49 am. Both are the same instant everywhere on Earth, printed here on the San Juan del Rio clock, which is why the calendar date can differ from the one a reader further east or west sees.

How far San Juan del Rio is from other cities

Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to San Juan del Rio is Santiago de Queretaro, Mexico at 46 km, and the furthest is Port Louis, Mauritius at 17,669 km, which is 88% of the way to being exactly opposite.

The antipode of San Juan del Rio

Dig straight through the centre of the Earth from San Juan del Rio, Mexico and you come out at 20.39 degrees south, 80.00 degrees east. That point is in the Indian Ocean. The nearest city in our catalogue to it is Port Louis, Mauritius, 2,346 km away from the antipode itself, where the clock currently reads 10:42 am on Sunday.

The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 20.39 degrees north becomes 20.39 degrees south, and 100.00 degrees west becomes 80.00 degrees east. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: San Juan del Rio is no exception. The local time at the antipode runs close to UTC+6, roughly twelve hours from San Juan del Rio, because a half turn of longitude is a half turn of the day.

Sunrise and sunset in San Juan del Rio

Today the sun rises in San Juan del Rio at 6:30 am and sets at 6:31 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 San Juan del Rio.

Sun and moon in San Juan del Rio today

The sun is up in San Juan del Rio for 12 hours 1 minute today, from 6:30 am to 6:31 pm. The moon sets in San Juan del Rio at 7:19 am and comes up again at 7:10 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 San Juan del Rio

Seven days from September 27, 2026, computed for San Juan del Rio, Mexico at 20.39 degrees north, 100.00 degrees west, on the clock of America/Mexico_City. 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 San Juan del Rio, Mexico, 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 Juan del Rio

From San Juan del Rio, Mexico the qibla is 45.5 degrees on a true compass, which is northeast, or 44.5 degrees north of due east. The Kaaba is 13,638 km away, 8,474 miles, measured over the surface of the Earth.

That figure is the initial bearing of the great circle from San Juan del Rio, Mexico 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 Juan del Rio, Mexico 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.
