Thailand Commemorates National Flag Day on September 28
The Department of Water Resources held a special event to mark National Flag Day, honoring the history and significance of the Thai national flag.
On September 28, 2026, the Department of Water Resources (DWR) organized a commemorative event to observe National Flag Day. This annual occasion honors the royal decree issued by King Rama VI in 1917, which established the current design of the Thai national flag, known as the 'Trairong' or tricolor flag.
For residents and travelers in Thailand, this day serves as a moment of national pride and historical reflection. While the event held by the DWR focused on internal organizational participation, the day is recognized nationwide with various ceremonies and the display of the national flag at government offices and public institutions.
Understanding the significance of the flag is a key aspect of appreciating Thai culture and history. The three colors represent the nation (red), religion (white), and the monarchy (blue). Visitors may notice increased displays of the flag throughout the country during this period. As this is a commemorative day rather than a public holiday, most businesses and public services operate on their regular schedules. No further official changes to public operations or travel requirements have been announced in connection with this observance.
