About National Day (Thailand)

National Day (Thailand) is the national day of Thailand. It marks the birthday of the late King Bhumibol Adulyadej.

In 2026 it falls on a Saturday; in 2027 it’s on Sunday 5 December, and in 2028 on Tuesday 5 December. This time it falls at the weekend; some countries move the day off to a weekday when that happens. Also in December 2026: Hanukkah (4 Dec), International Volunteer Day (5 Dec) and World Soil Day (5 Dec). From this page you can add it to your calendar, get an email before it, share the countdown, or show it full screen.
