National flag

"The current national flag of Thailand was adopted on September 28 in 1917 (B.E.2460) by Rama VI (King Vajiravudh).
(Until then, the design of a white elephant on a red background had been used since the era of Rama IV.)
Like the design above, the national flag of Thailand is called "Thong Trairong"; Blue stripe in the middle, white bands up and down of it, and red stripes sandwiches them.
Those colours have important meanings below:
- Blue: The monarchy of Thailand.
- White: Buddhism
(looks like it came from white elephant that is very sacred for Thai people)
- Red: Thai people
On week days (I don't know about weekends) , the national flag is raised at 8.00 a.m. and lowered at 6.00 p.m. at public places, offices and schools mostly with the Thai National Anthem.
