The middle of April coincides with traditional New Year celebrations in predominantly Theravada Buddhist countries within Southeast Asia. These are some of the most anticipated festivals in Southeast Asia.
Thailand's Songkran, Cambodia's Chol Chnam Thmey, Laos' Bun Pi Mai, and Myanmar's Thingyan all occur within days of each other, derived from the Buddhist calendar, and scheduled to coincide with the end of the planting season (a window of rare leisure in the year's hectic planting schedule).
Songkran in Thailand
Songkran is known as "the Water Festival" – Thais believe that water will wash away bad luck, and spend the day liberally splashing water on each other. Foreigners are not spared from this tradition - if you're out and about on Songkran, don't expect to return to your hotel room dry!
Songkran begins on April 13, the end of the old year, and concludes on the 15th, the first day of the New Year. Most Thais spend these days with their families, rushing home to the provinces from which they came. Unsurprisingly, Bangkok can be relatively quiet at this time of year.
As Songkran is an official holiday, all schools, banks, and government institutions are closed throughout the festival’s three days. Houses are cleaned and Buddha statues washed, while younger folk pay their respects to their seniors by respectfully pouring scented water on their hands.

Bun Pi Mai in Laos
The New Year in Laos - known as Bun Pi Mai - is almost as splashy as the celebrations over in neighboring Thailand, but getting soaked in Laos is a more gentle process than in Bangkok.
Bun Pi Mai takes place over three days, during which (the Lao believe) the old spirit of Songkran leaves this plane, making way for a new one. Lao bathe Buddha images in their local temples during Bun Pi Mai, pouring jasmine-scented water and flower petals on the sculptures.
The Lao respectfully pour water on monks and elders during Bun Pi Mai, and less reverently on each other! Foreigners are not exempt from this treatment - if you're in Laos during Bun Pi Mai, do expect to be soaked by passing teenagers, who'll give you the wet treatment from buckets of water, hoses, or high-pressure water guns.

Chol Chnam Thmey in Cambodia
Chol Chnam Thmey marks the end of the traditional harvest season, a time of leisure for farmers who have toiled all year to plant and harvest rice.
Until the 13th century, the Khmer New Year was celebrated in late November or early December. A Khmer King (either Suriyavaraman II or Jayavaraman VII, depending on who you ask) moved the celebration to coincide with the end of the rice harvest.
The Khmer mark their New Year with purification ceremonies, visits to temples, and playing traditional games.
At home, observant Khmer do their spring cleaning, and set up altars to offer sacrifices to the sky deities, or devodas, who are believed to make their way to the Mount Meru of legend at this time of year.
At the temples, entrances are garlanded with coconut leaves and flowers. Khmer offer food offerings to their departed relatives at the pagodas, and play traditional games in the temple courtyard. There isn't much in the way of monetary rewards to the winners - just the slightly sadistic fun of rapping the losers' joints with solid objects!

Thingyan in Myanmar
Thingyan - one of Myanmar's most anticipated festivals - takes place over a period of four or five days. As with the rest of the region, water throwing is a major part of the holidays, with the streets being patrolled by flatbed trucks bearing revelers throwing water on passersby.
Unlike the rest of the region, though, the holiday derives from Hindu folklore - it's believed that Thagyamin (Indra) visits the Earth on this day. People are supposed to take the splashing in good fun and hide any annoyance - or else risk Thagyamin's disapproval.
To please Thagyamin, feeding of the poor and alms-giving to monks are celebrated during Thingyan. Young girls shampoo or bathe their elders as a sign of respect
