It is 8:46 pm in Pacific/Guam

Pacific/Guam is the IANA identifier for the time zone of Guam in Guam. It is running at UTC+10 right now, with no letter abbreviation in common use, and the local date is Friday, September 25, 2026. The zone never moves its clocks.

What time is it in Pacific/Guam right now

8:46 pm on Friday, September 25, 2026, as this page was served, which in 24 hour form is 20:46. The clock above ticks on from there in your own browser. The offset is a whole 10 hours ahead of UTC, so a UTC timestamp converts here by changing the hour and leaving the minutes exactly as they are.

12 other zones read UTC+10 at this instant. They are interchangeable as a clock reading today and not as an identifier: storing UTC+10 instead of Pacific/Guam throws away the rule that decides what they all do at the next transition.

The UTC offset of Pacific/Guam

An offset of UTC+10 names the meridian 150.0 degrees east. Hagatna, Guam actually sits at 144.75 degrees east, which is 5.2 degrees west of it, so the sun there runs about 21 minutes behind the clock before daylight saving is even considered. Zone boundaries are drawn by borders and by convenience, not by longitude, and this is the size of the gap that produces.

Because this zone never moves its clocks, UTC+10 is the answer on every day of the year. That makes it an easy zone to schedule against, with the caveat that the other end of the call may still be moving its own clocks, so the gap between the two changes even though nothing changed here.

Daylight saving in Pacific/Guam

Pacific/Guam does not observe daylight saving. It sits at UTC+10 in January and reads UTC+10 again in July, so a gap worked out against it today is still right in six months. It did move them once: the sampling below shows a summer offset as late as 1977, and the practice has since been dropped.

The database holds no clock change for Pacific/Guam in 2025, 2026 or 2027, so there is no transition table to print. The offset shown at the top of this page is the offset on every date in those three years.

How the offset of Pacific/Guam has changed since 1970

Read on 1 January and 1 July of each year, which is the cheapest pair of samples that shows both the winter offset and whether the clocks moved that summer. The zone has passed through 6 distinct eras in that time and has used 2 different offsets: UTC+10, UTC+11. Its current behaviour has held since 1978. A rule change that began and ended between July and the following January is invisible to this sampling, so the table is a shape rather than a complete edit history.

The last summer in which Pacific/Guam read a different offset from its own January was 1977. Software that still carries a hand-written summer rule for this zone has been wrong every year since.

Countries and regions that use Pacific/Guam

One country uses Pacific/Guam: Guam, which keeps this as its only time zone and has a population of about 172,000.

Cities in the Pacific/Guam time zone

This site does not yet carry a city page inside Pacific/Guam, so the readings here are computed for the identifier itself and anchored at Hagatna, Guam. That costs nothing in accuracy: an offset is a property of the zone, not of a settlement, so the clock above is right for every point inside it. The city index lists the 6,338 places that do have their own page.

The sun against the clock in Pacific/Guam

Worked out for Hagatna, Guam, the capital of a country that keeps the zone, at 13.47 degrees north, 144.75 degrees east. The sun rises at 6:10 am and sets at 6:15 pm, giving 12 hours 5 minutes of daylight. Solar noon, the moment the sun is highest, falls at 12:13 pm, which is 13 minutes after clock noon.

That gap is the whole argument about where zone lines belong, in one number. It is made of three things: Hagatna, Guam sitting 5.2 degrees west of the UTC+10 meridian, the equation of time, which today runs 8.2 minutes ahead of mean time, and no daylight saving at all, because this zone does not use it.

Convert Pacific/Guam to another time zone

The converter is keyed on the abbreviations people type rather than on identifiers. Pacific/Guam is at UTC+10 right now, the same reading as AEST, so these pages answer the same question for it today. They will diverge if the two zones ever adopt different daylight saving rules, which is exactly why the identifier is the thing worth storing.

Questions about Pacific/Guam

What time is it in Pacific/Guam right now?

8:46 pm on Friday, September 25, 2026, as this page was served. The clock at the top of the page ticks on from there.

What is the UTC offset of Pacific/Guam?

UTC+10 at this instant, on every day of the year.

Does Pacific/Guam observe daylight saving time?

No. It stays at UTC+10 all year, and has done since 1978.

What is the abbreviation for Pacific/Guam?

There is no English letter abbreviation in common use for this zone, so it is written as its offset, UTC+10. That is what every other clock shows for it too.

Which countries use Pacific/Guam?

Guam.

Why store Pacific/Guam instead of UTC+10?

Because the offset is an output and the identifier is the input. This zone has one offset today and no guarantee of keeping it, and 12 other zones share its current reading while carrying different rules. A record storing UTC+10 cannot tell them apart; a record storing Pacific/Guam keeps working through every future rule change.
