What time is it in Guantanamo right now?

The time in Guantanamo, Cuba is 1:21 am, 01:21 on a 24 hour clock, on Sunday September 27, 2026. The reading above ticks from your own device against the America/Havana rules, so it stays right through a clock change rather than drifting an hour out twice a year.

Guantanamo sits at 20.14 degrees north and 75.21 degrees west, inside the tropics, north of the equator and 2,240 km from the equator. Its clock is set to a zone whose nominal meridian is 60.0 degrees west, and the city itself is 15.2 degrees west of that line. Those 15.2 degrees are worth 60 minutes 50 seconds of sun time, which is most of why solar noon here lands at 12:52 pm rather than on the stroke of twelve.

Guantanamo time zone and UTC offset

The IANA zone for Guantanamo, Cuba is America/Havana. Right now it is running at UTC-4 and the abbreviation in force is CDT. Guantanamo is on summer time at the moment, which is why the offset reads UTC-4 rather than the UTC-5 it keeps in winter.

Daylight hours in Guantanamo today

The full month by month picture for this city, the extremes of the year and every twilight band are on the sunrise and sunset page for Guantanamo, which works from the same coordinates.

Where Guantanamo 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 Guantanamo 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 Guantanamo.

Best time to call Guantanamo

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 America/Havana time

31 of our cities keep America/Havana, so every one of them reads 1:21 am at this moment and changes its clocks on the same night as Guantanamo. Nearest first:

Moon phase over Guantanamo 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 26, 2026 at 12:11 am Havana time, and the next new moon on October 10, 2026 at 11:49 am. Both are the same instant everywhere on Earth, printed here on the Guantanamo clock, which is why the calendar date can differ from the one a reader further east or west sees.

When the clocks change in Guantanamo

The next change is on Sunday, November 1, 2026, 35 days from now, when the clocks in Guantanamo go back 1 hour at 12:59 am and the offset moves from UTC-4 to UTC-5.

Two things follow from that. Any standing call with Guantanamo 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.

How far Guantanamo is from other cities

Great-circle distance, computed from the coordinates rather than road mileage. The nearest city we cover to Guantanamo is Santiago de Cuba, Cuba at 65 km, and the furthest is Cilacap, Indonesia at 18,561 km, which is 93% of the way to being exactly opposite.

The antipode of Guantanamo

Dig straight through the centre of the Earth from Guantanamo, Cuba and you come out at 20.14 degrees south, 104.79 degrees east. That point is in the Indian Ocean. The nearest city in our catalogue to it is Cilacap, Indonesia, 1,454 km away from the antipode itself, where the clock currently reads 12:21 pm on Sunday.

The antipode is worked out by flipping the latitude across the equator and swinging the longitude a half turn: 20.14 degrees north becomes 20.14 degrees south, and 75.21 degrees west becomes 104.79 degrees east. Two thirds of the planet is ocean and the land is unevenly spread, so most antipodes are open water: Guantanamo is no exception. The local time at the antipode runs close to UTC+8, roughly twelve hours from Guantanamo, because a half turn of longitude is a half turn of the day.

Sunrise and sunset in Guantanamo

Today the sun rises in Guantanamo at 6:51 am and sets at 6:52 pm, giving 12 hours 2 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 Guantanamo.

Sun and moon in Guantanamo today

The sun is up in Guantanamo for 12 hours 2 minutes today, from 6:51 am to 6:52 pm. The moon sets in Guantanamo at 7:35 am and comes up again at 7:28 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 Guantanamo

Seven days from September 27, 2026, computed for Guantanamo, Cuba at 20.14 degrees north, 75.21 degrees west, on the clock of America/Havana. 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 Guantanamo, Cuba, 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 Guantanamo

From Guantanamo, Cuba the qibla is 60.4 degrees on a true compass, which is east-northeast, or 29.6 degrees north of due east. The Kaaba is 11,578 km away, 7,194 miles, measured over the surface of the Earth.

That figure is the initial bearing of the great circle from Guantanamo, Cuba 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 Guantanamo, Cuba 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.
