This auspicious day it’s training is fixed by the Royal Brahman astrologers, and it takes place in the second week of May at Sanam Luang. IT is the official beginning of the rice-planting season in Thailand. Nowadays, although His Majesty the king is present at the ceremony, he no longer take a leading role. He appoints the Ploughing Lord or Phraya Rack Na, which is usually the Permanent Secretary of the Ministry of Agriculture, as his representative to carry out the ritual.
