Khmer New Year, known as Chol Chnam Thmay, is the grandest celebration on Cambodia's calendar. Held every April, it fills the streets, temples, and family homes with music, water, and laughter. Knowing the key Khmer New Year dos and don'ts beforehand will help you take part with confidence and leave a good impression on the people you meet.
Khmer New Year signals the close of the harvest season and the coming of the rains. It typically falls on April 14, 15, and 16 each year, though it can run for four days in certain years. The festival draws from Buddhist values and puts family, community, and gratitude at the center of every activity. For Cambodians, this is far more than a long weekend; it is the most sacred and anticipated time on the entire yearly calendar.

Temples are central to Khmer New Year, so dress with care before you visit. Tops should cover the shoulders, and bottoms should reach at least the knees. Thin cotton clothing is a smart pick - it is breathable in the mid-April heat while still being appropriate. Women in particular should keep a light scarf on hand to wrap around their shoulders or waist when stepping inside a pagoda.
Getting soaked is basically a requirement during Khmer New Year. The water splashing tradition represents a fresh start, washing away troubles from the past year and inviting good luck for the one ahead. Find a spot on a lively street, fill up a bucket or water gun, and join in without hesitation. Before you head out, seal your phone and valuables inside a waterproof pouch. Stick to quick-dry fabrics and leave your good shoes at home.

A trip to a local pagoda during the New Year is something you will not forget easily. Temples open their doors for free and extend their hours over the three days of celebration. Visitors can watch the Buddha bathing ceremony, observe monks receiving alms, and see families carefully build sand mounds in the courtyards. Move quietly, stay respectful, and take it all in, no tour guide needed.

Certain dishes only appear during Chol Chnam Thmay, so use the chance to taste them while you can. Kralan is a standout - glutinous rice packed into a fresh bamboo tube and slow-roasted over open fire. Num Ansom, a banana-leaf parcel of sticky rice and coconut, is another festival staple. Look for these at outdoor markets, roadside stalls, and pop-up food stands near popular gathering spots.

This phrase, pronounced roughly as "Chool ch-nam t’may", is how Cambodians wish each other a Happy New Year. Saying it to a local, even with a heavy foreign accent, will almost always be met with warmth and laughter. It signals that you made an effort to connect, and that small gesture can open up genuine conversations throughout your visit.

Feet carry a specific cultural weight in Khmer society - they are seen as the lowest and least honorable part of the body. When sitting on the floor at a temple or inside a local home, tuck your feet to the side rather than letting them point toward others. Never angle the soles of your feet at a Buddha statue, a shrine, or an older family member. It is a small habit to pick up, but it shows a level of respect that Cambodians will notice and appreciate.
The urge to photograph everything during such a colorful festival is understandable, but hold back in certain situations. Always ask before pointing your camera at someone, especially during prayer or quiet ritual moments. Some pagodas do not allow photography inside their walls at all. A simple smile and a raised camera is usually question enough, and most people will respond warmly if they are comfortable.
The water fights are loud, fun, and hard to resist, but there are clear lines to respect. Monks, elderly people, and very young children should never be the target of a splash. The act of pouring water gently over Buddha statues and offering it to elders carries a sacred meaning that sits far apart from the street-level play. Watch how locals interact with one another and let their behavior be your guide.
In the courtyard of most pagodas, families spend hours shaping small mounds of sand during the New Year period. This practice, known as Puung Phnom Khsach, is a sincere act of devotion, believed to bring spiritual merit and blessings to those who take part. The sand structures are not decorations or props. Do not step on them, touch them, or use the area around them as a backdrop for photos. Pause for a moment to appreciate the care that went into building them before moving on.
