Cambodian Events in May

Visak Bochea Day (Buddha Day)

Visak Bochea Day is observed on the full moon of the 6th month of the Buddhist lunar calendar. This day is significant for Cambodian Buddhists as it commemorates the birth, enlightenment, and nirvana of Gautama Buddha. Buddhists visit temples and shrines, offering food, candles, and flowers to monks. It’s a day dedicated to reflecting on Buddha’s teachings, striving for peace, and leading a noble life.

Common rituals include bathing the Buddha statue, sharing vegetarian meals, and decorating homes and streets with flowers and Buddhist flags.

Royal Ploughing Ceremony

Royal Ploughing Ceremony is held in open field near the National Museum and next to the Royal Palace.

The Royal Ploughing Ceremony, known as Bon Chroat Preah Nongkoal, is an ancient rite that marks the beginning of the rice-growing and rainy seasons in Cambodia. This ceremony, rooted in the historical governing rules of Satra, signifies the preparation for farming activities. One of its primary purposes is to pray for a bountiful harvest. Booking a Siem Reap tour in advance is recommended, especially if you plan to visit during the Royal Ploughing Ceremony.

During this event, the King, or a designated representative, ploughs a field with royal oxen, while the Queen sows seeds. The procession includes trays of various seeds and offerings. The oxen’s choice from these trays is believed to predict the upcoming season’s agricultural success. If you are in Cambodia during this time, visiting Phnom Penh offers a unique opportunity to witness this fascinating ceremony near the National Museum and Royal Palace.

King Sihamoni, born in 1953, has a rich background in arts and culture, having lived and studied in the Czech Republic, North Korea, and France. He is fluent in multiple languages and served as Cambodia’s delegate to UNESCO before ascending to the throne in 2004.
