The monarchy holds a central and deeply respected place in Thai life. Several of the year’s national holidays honour the King, the Queen and past monarchs. Here is a factual guide to those days and to showing respect at royal occasions and sites.
Thailand is a constitutional monarchy. The constitution names the King as the upholder of religions, and royal imagery and ceremony are a visible, everyday part of public life. Many royal occasions are also national public holidays, when government offices and banks close. The days below are the 2026 royal public holidays, drawn from our sourced national holiday calendar.

Thailand has strict laws protecting the monarchy. Whatever your personal views, the simplest and most respectful approach is to treat the royal family, royal images and royal sites with courtesy, and to avoid disrespectful comments, gestures or images — in person and on social media. Behaving respectfully here is both expected and easy.
