The Royal Ploughing Ceremony is an ancient royal rite held in many Asian countries to mark the traditional beginning of the rice growing season. The royal ploughing ceremony, called Lehtun Mingala or Mingala Ledaw was also practiced in pre-colonial Burma until 1885 when the monarchy was abolished.
In Thailand, the common name of the ceremony is Raek Na Khwan which literally means the “auspicious beginning of the rice growing season”. The royal ceremony is called Phra Ratcha Phithi Charot Phra Nangkhan Raek Na Khwan which literally means the “royal ploughing ceremony marking the auspicious beginning of the rice growing season”
The Buddhist part is conducted in the Grand Palace first and is followed by the Hindu part held at Sanam Luang, Bangkok.
At present, the day on which Phra Ratcha Phithi Phuetcha Mongkhon Charot Phra Nangkhan Raek Na Khwan is held is called Phuetcha Mongkhon Day It has been a public holiday since 1957
