You’re probably used to the ball dropping in Times Square on January 1st. Most of the world is. But if you find yourself in Phnom Penh or the dusty, ancient streets of Siem Reap during the middle of April, you’ll realize the calendar works a bit differently here. When is Cambodian New Year? It isn’t a fixed date like Christmas. Well, technically it follows the Gregorian calendar now for the sake of government sanity, but its roots are buried deep in ancient solar cycles.
In 2026, the celebration—known locally as Chaul Chnam Thmey—officially kicks off on April 14th. It usually runs for three or four days.
It’s hot. Brutally hot. We are talking about the peak of the dry season where the humidity feels like a wet wool blanket and the sun turns the pavement into a griddle. Yet, this is when the entire country decides to throw the biggest party of the year. It’s a time of transition. The harvest is over. The farmers are finally catching their breath before the monsoon rains arrive to turn the parched earth into a sea of green. If you aren't prepared for the chaos, the powder, and the water, you’re in for a massive shock.
The Three Days of Chaul Chnam Thmey
Most people think it’s just one big party. It’s not. Each day has a specific name and a very specific vibe. It’s a progression from the spiritual to the playful.
Moha Sangkran is day one. This is the "welcoming" day. People believe an angel comes down to earth to take over the "guard duty" for the year. To make sure the angel doesn't skip their house, families clean everything. I mean everything. They set up altars with fruit, drinks, and incense. You'll see people wearing their best clothes, heading to the pagodas to offer food to monks. It’s surprisingly quiet in the mornings, filled with the smell of jasmine and heavy incense smoke.
Then comes Veareak Vanabat, the second day. This one is all about others. It’s a day of charity. People give gifts to parents, grandparents, and the poor. There’s a beautiful tradition of building sand mounds (called valuka chedei) at the pagodas. These mounds represent the Culamani Cetiya, a stupa in heaven. It’s a way to pay respects to ancestors and ask for blessings. It’s a bit more somber, a bit more reflective.
Finally, you hit Veareak Laeung Sak. This is the third day, and it’s when things get a little wild. This is the "New Beginning." People wash the Buddha statues with scented water. Then, they wash their elders. It’s supposed to bring longevity and luck. But for the younger generation, this "washing" tradition has evolved into a nationwide water fight. If you walk outside in a white t-shirt, you’re a target. You’ll be soaked in seconds. It’s glorious.

Why April? The Solar Connection
You might wonder why they don’t just celebrate in January. It’s a fair question. Historically, Cambodia actually celebrated the New Year in the first month of the lunar calendar (around November or December).
But then the Angkorian kings stepped in.
They realized that November was the peak of the harvest. If you tell a bunch of rice farmers to stop working and party for three days while the crops are ready to be picked, you’re going to have a famine. So, the holiday was shifted to the fifth month of the lunar calendar—April. By then, the rice is in the silos. The ground is too hard to plow anyway. It’s the perfect time to stop, pray for rain, and throw some water at your neighbor.
Unlike the Chinese New Year, which follows a strictly lunar cycle and bounces around January and February, the Cambodian New Year is solar-based. It marks the sun entering the sign of Aries. This is why the dates are almost always April 13th or 14th. It aligns with the "Songkran" festivals you see in Thailand, Laos, and parts of Myanmar.
What Most People Get Wrong About the Celebration
If you search for travel tips, you’ll see people telling you to go to Angkor Wat for the "Angkor Sangkran." Honestly? It’s a bit of a double-edged sword. Yes, the government puts on massive displays, traditional games like Chol Chhoung (a cloth-throwing game) and Chhoung are played everywhere, and the atmosphere is electric.
But it’s also crowded. Beyond belief.

A lot of visitors think they’ll get to see the temples in peace. Forget it. Half of Cambodia is at Angkor Wat during New Year. The traffic jams in Siem Reap can last for hours. If you want a more "authentic" (and less suffocating) experience, head to the smaller provinces. Places like Battambang or even the quiet coastal towns offer a much more intimate look at how families actually celebrate.
Another misconception is that it's just a "water festival." That's technically Bon Om Touk, which happens in November. While water is a huge part of New Year, the focus here is on the Sangkran—the transition. It's more spiritual than the November boat races.
The Games People Play (Literally)
Cambodians are obsessed with traditional games during this week. You’ll see circles of people in the streets or on temple grounds.
- Leah Koh: Basically a version of "tag" but with very specific rules and a lot of laughing.
- Leak Kanseng: One person hides a twisted towel behind someone in a circle. If you don't notice it, you're "out" or get a playful "hit" with the towel.
- Tug-of-War: It’s not just for kids. Entire villages compete.
These games aren't just for fun; they are deeply communal. In a world that's becoming increasingly digital, seeing a bunch of teenagers putting down their phones to play a game with a rolled-up krama (scarf) is actually pretty refreshing.
Practical Survival Tips for the Heat and Chaos
If you are planning to be there, you need a strategy. This isn't a "wing it" kind of holiday.
- Book everything months in advance. Hotels in Siem Reap and Phnom Penh fill up fast. Prices often double or triple.
- Waterproof everything. Buy a dry bag for your phone and camera. Even if you think you’re just going for a quick walk to the 7-Eleven, someone will dump a bucket of ice water on you.
- Respect the Pagoda. While the streets are a party, the temples are still places of worship. Dress modestly (shoulders and knees covered). Don't be the tourist who walks into a blessing ceremony in a bikini top.
- Hydrate or die. Not literally, but the heat is no joke. Drink way more water than you think you need. The combination of beer and 100-degree weather is a recipe for a bad time.
- Learn the greeting. "Sua Sdei Chnam Thmey" (pronounced roughly like Swa-day Ch-nam T-may). It means Happy New Year. Say it to a local, and you’ll get a massive grin in return.
The Cultural Nuance You Won't Find in Most Guides
There is a subtle social hierarchy to the water throwing. In the West, we think of it as a free-for-all. In Cambodia, you generally don't throw water at monks or the elderly unless it's the ritualistic "pouring" over the hands. If you blast a 70-year-old grandmother in the face with a high-powered water gun, you’re going to look like a jerk. Stick to your own age group or people who are clearly already participating.

Also, be prepared for the talcum powder. People will rub a white paste (powder mixed with water) on your face. It's a blessing. It’s also very messy. Don't wear your favorite designer shirt.
Final Insights for the Modern Traveler
The Cambodian New Year is a beautiful, sweaty, loud, and deeply spiritual mess. It’s the best way to see the "real" Cambodia—a country that has survived so much and still knows how to find joy in the transition of the seasons.
If you want the party, stay in the cities. If you want the soul, find a village.
To make the most of your trip, aim to arrive two days before the official start. This lets you see the preparations—the stringing of lights, the cleaning of houses, and the general sense of anticipation that builds up in the air. By the time April 16th or 17th rolls around, the country will go back to work, the streets will be covered in dried white powder, and the long wait for the monsoon rains will begin in earnest.
Next Steps for Your Trip Planning:
- Check the specific 2026 dates with the Cambodian Ministry of Tourism website about a month before you fly, as sometimes additional "public holiday" days are added to the start or end.
- Purchase a high-quality krama (traditional scarf) upon arrival; it’s perfect for wiping sweat, shielding from the sun, or using as a makeshift towel during the water fights.
- Locate the nearest medical clinic in your area, as heat exhaustion is the most common issue for foreigners during the April festivities.
