Here's the live public holiday calendar for Thailand — recently observed dates plus upcoming ones, kept current automatically rather than a fixed yearly list. Thailand observes 2 official public holidays mandated by national law (including Chulalongkorn Day (Wan Piyamaharaj), King Bhumibol Adulyadej Birthday & National Day). Some holidays fall on a fixed calendar date every year — an Independence or Republic Day, for instance. Others, governed by the Easter calculation, the Islamic lunar calendar, or an "nth weekday of the month" rule, shift from year to year, so each year carries its own actual date rather than an assumed repeat. Jump straight to the live calendar below, or read on for how the dates are worked out.
Why This Matters: Public holidays in Thailand directly affect cross-border trade timing and payment settlement windows. This calendar is a standard reference point for market research teams tracking regional business cycles working with partners, offices or operations in Thailand.

Statutory public holidays mandated by national government law in Thailand. These fixed dates reflect official non-working days. For dynamic, movable religious observances (e.g., Eid, Easter), refer to the live calendar embed above.

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. Thailand's calendar can include holidays governed by the Easter computus that many Christian-majority countries use, the Hijri lunar calendar behind Islamic observances such as Eid al-Fitr and Eid al-Adha, or a lunisolar cycle behind holidays like Lunar New Year. Thailand, like much of Asia, 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 Thailand's labor law, fixed-date national public holidays carry mandatory non-working status for public administration, financial institutions, and commercial enterprises — 2 such holidays are documented for Thailand in the table above, currently sourced from Thailand's official government portal, pending independent confirmation, including Chulalongkorn Day (Wan Piyamaharaj) on October 23. Official gazette announcements are published by government authorities to confirm these mandated closures.
Worth separating, too: a true public holiday is a legally mandated non-working day — banks, schools and government offices close by law or long-standing custom. An observance is different — culturally or religiously notable, but without a mandated closure (Valentine's Day and Earth Day are common examples worldwide). This page focuses specifically on public holidays, the ones that actually affect scheduling.
Thailand is also divided into states and provinces, and countries structured this way often layer a regional founding day, a local patron festival or a province-specific holiday on top of the national calendar — observed in one state but not nationwide. The calendar above covers Thailand's national holidays; see the Thailand states & provinces directory for population and government data on each one.
