About the time in Guam
The zone identifier Pacific/Guam is the value you want in code, calendars and travel systems. Abbreviations change with the season, but Pacific/Guam keeps pointing at Guam time whatever the date, which is why every timestamp on this page is built from it.
Sunrise today lands at 06:08 and sunset at 06:39 local time, giving 12h 31m of daylight. Those figures come from the city's own coordinates (13.48, 144.82) rather than a country-wide average, so they match what you would actually see from a window in Guam.
Clocks in Guam stay put all year. There is no summer-time switch to remember, so UTC +10 is what you will get in January and in July alike — useful if you book recurring calls with people in Guam.
