Khmer New Year, known as 'Choul Chnam Thmey' in the Khmer language, is the most important holiday in Cambodia. This grand national event falls on April 13th or 14th, depending on the ancient horoscope “MohaSangkran.” The holiday lasts for three days and gives Cambodians the opportunity to return to their home communities and enjoy festivities.

Each of the three days of Khmer New Year has its own distinct rituals and traditions. The first day is known as 'Moha Sangkran,' when Cambodians decorate their homes and offer a meal to the spirit god. The second day, 'Vanabot,' is marked by charitable acts and gift-giving, with locals demonstrating compassion and humanity towards each other. The third day, 'Leung Sakk,' is when Cambodians bathe their Buddha statues and elders with perfumed water as a symbol of respect and purging any negativity from the previous year.

Aside from the formal ceremonies and rituals, Khmer New Year is also a time for fun-filled activities and vibrant celebrations. There is a wide array of traditional games like 'Chol Chhoung,' 'Leak Kanseng', and 'Chab Komnort' that are enjoyed by everyone irrespective of their age. Street dances, music, and eating special dishes are common sights during this celebration that binds the whole country in a festive spirit.
