Public holidays generally split into two kinds: fixed-date ones that land on the same calendar day every year — a founding or independence anniversary, for instance — and movable ones whose date shifts annually because they follow a different calendar system entirely. Guam's calendar can include holidays governed by an Easter-based calculation, the Hijri lunar calendar used for Islamic observances, or a lunisolar calendar — each running independently of the standard Gregorian civic calendar. Guam, like much of Australia And Oceania, likely carries at least one holiday from each category on its calendar — one reason the list above shows a specific date per year instead of a single recurring one.
Under Guam's labor law, fixed-date national public holidays carry mandatory non-working status for public administration, financial institutions, and commercial enterprises — 1 such holiday is documented for Guam in the table above, currently sourced from Guam's official government portal, pending independent confirmation, including Liberation Day on July 21. Official gazette announcements are published by government authorities to confirm these mandated closures.
It's also worth distinguishing a public holiday from an observance. A public holiday is a government-mandated day off — offices, banks and schools close. An observance marks something culturally or religiously significant without requiring anyone to close for it. This page tracks public holidays only, since those are the dates that actually change a day's schedule.
Guam isn't divided into separate states or provinces the way some larger federated nations are, so its public holiday calendar applies uniformly nationwide — the dates shown above hold the same way across the whole country, without a regional layer to account for.
