What time is it in Piedras Negras right now?
The time in Piedras Negras, Mexico is 4:06 pm, 16:06 on a 24 hour clock, on Saturday September 26, 2026. The reading above ticks from your own device against the America/Matamoros rules, so it stays right through a clock change rather than drifting an hour out twice a year.
Piedras Negras sits at 28.70 degrees north and 100.52 degrees west, just outside the tropics and 3,191 km from the equator. Its clock is set to a zone whose nominal meridian is 75.0 degrees west, and the city itself is 25.5 degrees west of that line. Those 25.5 degrees are worth 102 minutes 6 seconds of sun time, which is most of why solar noon here lands at 1:33 pm rather than on the stroke of twelve.
Piedras Negras time zone and UTC offset
The IANA zone for Piedras Negras, Mexico is America/Matamoros. Right now it is running at UTC-5 and the abbreviation in force is CDT. Piedras Negras is on summer time at the moment, which is why the offset reads UTC-5 rather than the UTC-6 it keeps in winter.

Moon phase over Piedras Negras tonight
The moon is a waning gibbous tonight, 15.7 days into its cycle and about 99% lit. The next full moon falls on October 25, 2026 at 11:11 pm Matamoros time, and the next new moon on October 10, 2026 at 10:49 am. Both are the same instant everywhere on Earth, printed here on the Piedras Negras clock, which is why the calendar date can differ from the one a reader further east or west sees.
When the clocks change in Piedras Negras
The next change is on Sunday, November 1, 2026, 35 days from now, when the clocks in Piedras Negras go back 1 hour at 1:59 am and the offset moves from UTC-5 to UTC-6.
Two things follow from that. Any standing call with Piedras Negras shifts by an hour on that date unless the other side moves the same weekend, and every offset printed on this page is the offset for today rather than a fixed property of the city.

The antipode of Piedras Negras
Dig straight through the centre of the Earth from Piedras Negras, Mexico and you come out at 28.70 degrees south, 79.48 degrees east. That point is in the Indian Ocean. The nearest city in our catalogue to it is Vacoas, Mauritius, 2,409 km away from the antipode itself, where the clock currently reads 1:06 am on Sunday.
The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 28.70 degrees north becomes 28.70 degrees south, and 100.52 degrees west becomes 79.48 degrees east. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: Piedras Negras is no exception. The local time at the antipode runs close to UTC+7, roughly twelve hours from Piedras Negras, because a half turn of longitude is a half turn of the day.
Sunrise and sunset in Piedras Negras
Today the sun rises in Piedras Negras at 7:33 am and sets at 7:34 pm, giving 12 hours 1 minute of daylight.

Sun and moon in Piedras Negras today
The sun is up in Piedras Negras for 12 hours 1 minute today, from 7:33 am to 7:34 pm. The moon sets in Piedras Negras at 7:27 am and comes up again at 7:30 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 Piedras Negras |
|---|---|
| Astronomical dawn | 6:14 am |
| Nautical dawn | 6:42 am |
| Civil dawn | 7:09 am |
| Sunrise | 7:33 am |
| Solar noon | 1:33 pm |
| Sunset | 7:34 pm |
| Civil dusk | 7:57 pm |
| Nautical dusk | 8:25 pm |
| Astronomical dusk | 8:52 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 Piedras Negras | Length |
|---|---|---|
| Morning blue hour | 7:09 am to 7:18 am | 0h 09m |
| Morning golden hour | 7:18 am to 8:04 am | 0h 46m |
| Evening golden hour | 7:02 pm to 7:48 pm | 0h 46m |
| Evening blue hour | 7:48 pm to 7:57 pm | 0h 09m |
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 Piedras Negras |
|---|---|
| Moonrise | 7:30 pm |
| Moonset | 7:27 am |
| Phase | waning gibbous, waning |
| Illumination | 100% of the disc lit |
| Moon age | 15.6 days since the new moon |
| Distance | 379,400 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 Saturday, September 26, 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 9:00 am in Piedras Negras it is working hours in Piedras Negras, 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 Piedras Negras
Seven days from September 26, 2026, computed for Piedras Negras, Mexico at 28.70 degrees north, 100.52 degrees west, on the clock of America/Matamoros. 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 |

Dhuhr is solar noon at Piedras Negras, 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 Piedras Negras
From Piedras Negras, Mexico the qibla is 41.8 degrees on a true compass, which is northeast, or 41.8 degrees east of due north. The Kaaba is 13,005 km away, 8,081 miles, measured over the surface of the Earth.
That figure is the initial bearing of the great circle from Piedras Negras, 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 Piedras Negras, 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.
Put a Piedras Negras clock on your site
A live clock showing the current time in Piedras Negras, Mexico, ready to paste into any page that accepts HTML. It reads America/Matamoros from the time zone database, so it stays right when Piedras Negras changes its clocks, and it shows CDT to every visitor wherever they are reading from. It is a plain iframe: no account, no script to install, nothing to pay.
The box needs 183 pixels of height for these settings, which is what the code above sets, and the numbers show at full size from 305 pixels of width up. Narrower than that they scale down rather than wrapping, and turning a line off makes the box shorter. The code updates with either.
