What time is it in Guam right now? 🇬🇺

It is 9:19 pm in Hagatna right now, Friday, September 25, 2026. Guam runs on UTC+10. Every reading on this page is computed from the IANA time zone database at the moment you loaded it, and the clocks above and below tick on from there.

Time in Guam now

Guam keeps a single time zone, Pacific/Guam, so there is one answer to the question and it is the same in every town: 9:19 pm. The offset is UTC+10, and it never moves.

The offset from UTC in Hagatna is UTC+10, which is 10 hours ahead of Coordinated Universal Time. Nine in the morning in Hagatna is 11:00 pm UTC.

Guam time zone in full

Each row is a zone identifier from the IANA database, its reading at this instant, its offset from UTC and whether it is currently on standard or summer time. All of them agree today, which is the usual case for Guam.

Does Guam have daylight saving time?

No part of Guam moves its clocks. The offset stays at UTC+10 through the whole year, which means a difference worked out today against Guam is still right in six months. Most of the world now works this way; the daylight saving habit is concentrated in Europe, North America and a short list of others.

A fixed offset makes Guam an easy place to schedule against, with one caveat: the country at the other end of the call may still be moving its clocks, so the gap can change even though nothing changed here. The windows further down this page are worked out at the current instant for exactly that reason.

Time difference between Hagatna and major cities

Worked out at this instant rather than from a stored table, so daylight saving on either side is already in it.

Best time to call Guam

A nine to five working day in Hagatna against a nine to five day elsewhere. The overlap column is the stretch when both desks are open, given on each side's own clock.

Daylight hours in Hagatna today

In Hagatna the sun rose at 6:10 am today and sets at 6:15 pm, giving 12 hours 5 minutes of daylight. The capital is losing 45 seconds of daylight a day at the moment, and the sun stands highest at 12:13 pm.

Solar noon in Hagatna is 12:13 pm, which is 13 minutes after clock noon. That gap is the capital sitting at 144.75 degrees east while its clock is set to Pacific/Guam, plus the equation of time, which today runs 8.2 minutes ahead of mean time.

Moon phase over Hagatna tonight

The moon is full moon tonight, 14.3 days into the current lunation, with roughly 100 percent of the disc lit. The next full moon falls on September 27, 2026 as Guam reads the date, at 2:48 am local. The moon phase page has the full cycle.

Cities in Guam

This site does not yet carry a city page inside Guam, so the readings here are worked out for Hagatna and for each zone directly. The zone table above is the authoritative answer for anywhere in the country, because a zone applies to every settlement inside it regardless of whether we list the settlement.

Every IANA time zone in Guam

These are the identifiers a computer uses. A program that stores Pacific/Guam rather than UTC+10 keeps working through every future rule change, which is the whole reason the database is keyed this way.

Information about Guam

Guam sits in Oceania, carries the ISO country code GU and a population of about 172,000. Its capital Hagatna is at 13.47 degrees north, 144.75 degrees east, which is the coordinate every sunrise and solar noon on this page is computed from.

Upcoming dates in Guam

Read on Guam's own clock, so the day counts below start from September 25 and not from a UTC date. The list is the internationally observed calendar plus the dates common across Oceania, along with this country's own clock changes and the next solstices and equinoxes. National days set by a country's own statute are not included, because this site carries no statute table and a guessed one would be worse than an honest gap.

Sun and moon in Hagatna today

The sun is up in Hagatna for 12 hours 5 minutes today, from 6:10 am to 6:15 pm. The moon sets in Hagatna at 4:36 am and comes up again at 5:12 pm. The next phase is the full moon on September 27, 2026. It is 97% lit at the moment, a waxing gibbous, filling out by about 3.6 percentage points a day.

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 Hagatna

Seven days from September 25, 2026, computed for Hagatna at 13.47 degrees north, 144.75 degrees east, on the clock of Pacific/Guam. 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 Hagatna, 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 Hagatna

From Hagatna the qibla is 294.6 degrees on a true compass, which is west-northwest, or 24.6 degrees south of due west. The Kaaba is 10,954 km away, 6,807 miles, measured over the surface of the Earth.

That figure is the initial bearing of the great circle from Hagatna 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 Hagatna 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.
