In Thailand, the national and royal anthems are highly respected and hold great significance. There are two different anthems that you might encounter:

1. National Anthem (Phleng Chat) The Thai national anthem, known as "Phleng Chat" in Thai, plays daily on television and radio at 8 AM and 6 PM, and at other public times such as before the start of a movie in a cinema. When Thais hear the national anthem in public, it is customary for them to stop what they are doing and stand still to show respect. This practice extends to public places, schools, and even on the streets where pedestrians will halt and stand quietly until the anthem is finished.

2. Royal Anthem (Sansoen Phra Barami) The royal anthem is different from the national anthem and is usually played to honor the king before certain official events, ceremonies, and in cinemas before a movie starts. It's also played during cultural and traditional events. When the royal anthem is played, people are again expected to stand to show reverence for the monarchy, which has historically held a deeply respected position in Thai society.

Both practices are firmly ingrained in Thai culture as a sign of patriotism and respect for the nation and monarchy. Foreigners visiting or living in Thailand are also expected to adhere to these customs when they find themselves in situations where the anthems are being played. Not standing during the anthems can be perceived as disrespectful and may offend onlookers, so as a matter of courtesy and cultural sensitivity, visitors should follow the local practice.
