When is Royal Ploughing Ceremony?
In 2026, Royal Ploughing Ceremony falls on Wednesday, May 13, 2026. It is classified here as a Thai public holiday.
History of Royal Ploughing Ceremony
Royal Ploughing Ceremony Day in Thailand combines the Buddhist Phuetcha Mongkhon seed-blessing rite with the Brahmanic Charot Phra Nangkhan Raek Na Khwan ploughing ceremony. Royal ploughing traditions have deep Southeast Asian histories; the modern Thai ceremony was revived in 1960 after a period of suspension. It honours agriculture and ritually opens the rice-growing season rather than announcing a scientifically binding forecast for farmers.
At Sanam Luang, the Lord of the Ploughing Ceremony scatters consecrated rice seed while ceremonial oxen pull a plough. Their selection among offered foods and the Lord’s choice of cloth are interpreted as auguries concerning rainfall, crops and trade. Spectators traditionally collect scattered rice grains as auspicious seed. Since 1966 the Cabinet has also associated the ceremony with Farmers’ Day, recognising agriculture’s economic and cultural importance.
The Royal Household schedule placed the 2026 ceremonies on May 12–13, with Wednesday, May 13 the government holiday and ploughing day. It is not on the Bank of Thailand’s national financial-holiday list and is not automatically a private-sector holiday. The date is selected annually, so no future occurrence should be extrapolated; museums, farms and businesses follow their own operations.
