Thai Ministry of Interior Orders Nationwide Flag Display for September

On September 6, 2026, Khaosod Online reported that the Thai Ministry of Interior has issued a directive to governors of all 76 provinces, district chiefs, and local administrative organizations nationwide. The order mandates the display of the Thai national flag at all government offices throughout the month of September.

This initiative is part of the preparations for Thai National Flag Day, which is observed annually on September 28. According to Arphisit Samphantarat, Permanent Secretary of the Ministry of Interior, the campaign is coordinated with the Office of the Prime Minister to foster national pride and honor King Vajiravudh (Rama VI), who established the tricolor flag (Trairong) in 1917.

For residents and travelers, this directive means that government buildings and public spaces will be adorned with the national flag throughout the month. While this is a standard patriotic observance, visitors may notice increased displays of the flag during their travels. It is important to note that this is a directive for government entities; there are no specific requirements for private citizens or businesses to follow suit. As of now, the specific ceremonial activities planned for September 28 remain subject to further local announcements by individual provincial authorities.
