Chakri Day is celebrated in Thailand on April 6th.
This day commemorates the establishment of the Chakri Dynasty (the current ruling house) and the founding of Bangkok by King Rama I in 1782.
The national flag is displayed. People participate in traditional ceremonies and leave flowers and garlands at the statues of Kings in the House of Chakri.
The King and the royal family presides over religious ceremonies held at the royal chapel. He also pays respect to his predecessors at the Royal Pantheon and lays a wreath at the statue of King Rama I at the Memorial Bridge. All government officials take part in the wreath-laying ceremony.
