The Thai New Year (Thai: āļŠāļāļāļĢāļēāļāļāđ Songkran, from Sanskrit sankrÄnti “astrological passage”) is celebrated every year from April 13 to April 15. It coincides with the New Year of many other calendars in South and Southeast Asia.
The date of the festival was originally set by astrological calculation, but it is now fixed. If these days fall on a weekend, the missed days off are taken on the weekdays immediately following. If they fall in the middle of the week, many Thai take off from the previous Friday until the following Monday! Songkran falls in the hottest time of the year in Thailand, at the end of the dry season. Until 1888 the Thai New Year was the beginning of the year in Thailand; thereafter 1 April was used until 1940. 1 January is now the beginning of the year. The traditional Thai New Year has been a national holiday since then.
New year traditions
The most obvious celebration of Songkran is the throwing of water. People roam the streets with containers of water or water guns, or post themselves at the side of roads with a garden hose and drench each other and passersby. This, however, was not always the main activity of this festival. Songkran was traditionally a time to visit and pay respects to elders, including family members, friends and neighbors.
Besides the throwing of water, people celebrating Songkran may also go to a wat (Buddhist monastery) to pray and give food to monks. They may also cleanse Buddha images from household shrines as well as Buddha images at monasteries by gently pouring water mixed with a Thai fragrance (āļāđāļģāļāļāđāļāļĒ) over them. It is believed that doing this will bring good luck and prosperity for the New Year. In many cities, such as Chiang Mai, the Buddha images from all of the city’s important monasteries are paraded through the streets so that people can toss water at them, ritually ‘bathing’ the images, as they pass by on ornately decorated floats. In northern Thailand, people may carry handfuls of sand to their neighborhood monastery in order to recompense the dirt that they have carried away on their feet during the rest of the year. The sand is then sculpted into stupa-shaped piles and decorated with colorful flags.
Some people make New Year resolutions - to refrain from bad behavior, or to do good things. Songkran is a time for cleaning and renewal. Besides washing household Buddha images, many Thais also take this opportunity to give their home a thorough cleaning.
The throwing of water originated as a way to pay respect to people, by gently pouring a small amount of lustral water on other peopleâs hands or over a shoulder as a sign of respect. Among young people the holiday evolved to include dousing strangers with water to relieve the heat, since April is the hottest month in Thailand (temperatures can rise to over 100°F or 40°C on some days). This has further evolved into water fights and splashing water over people riding in vehicles.
Nowadays, the emphasis is on fun and water-throwing rather than on the festival’s spiritual and religious aspects, which sometimes prompts complaints from traditionalists. In recent years there have been calls to moderate the festival to lessen the many alcohol-related road accidents as well as injuries attributed to extreme behavior such as water being thrown in the faces of traveling motorcyclists.
The water is meant as a symbol of washing all of the bad away and is sometimes filled with fragrant herbs.
From Wikipedia, the free encyclopedia
Loy Krathong (or Loi Kratong, Thai āļĨāļāļĒāļāļĢāļ°āļāļ) is a festival celebrated annually throughout Thailand. It is held on the full moon of the 12th month in the traditional Thai lunar calendar. In the western calendar this usually falls in November.
“Loi” means “to float”. “Krathong” is a raft about a handspan in diameter traditionally made from a section of banana tree trunk (although modern-day versions use specially made bread ‘flowers’ and may use styrofoam), decorated with elaborately-folded banana leaves, flowers, candles, incense sticks etc. During the night of the full moon, many people will release a small raft like this on a river. Governmental offices, corporations and other organizations also build much bigger and more elaborate rafts, and these are often judged in contests. In addition, fireworks and beauty contests take place during the festival.
The festival probably originated in India as a Hindu festival similar to Divali as thanksgiving to the deity of the Ganges with floating lanterns for giving life throughout the year.
According to the writings of H.M. King Rama IV in 1863, the originally Brahmanical festival was adapted by Buddhists in Thailand as a ceremony to honour the original Buddha, Siddhartha Guatama. Apart from venerating the Buddha with light (the candle on the raft), the act of floating away the candle raft is symbolic of letting go of all one’s grudges, anger and defilements, so that one can start life afresh on a better foot. People will also cut their fingernails and hair and add them to the raft as a symbol of letting go of the bad parts of oneself. Many Thai believe that floating a krathong will create good luck, and they do it to honor and thank the Goddess of Water, Phra Mae Khongkha.
The beauty contests that accompany the festival are known as “Noppamas Queen Contests”. According to legend, Noppamas was a consort of the Sukothai king Loethai (14th century) and she was the first to float decorated krathongs.
 
The Thai tradition of Loy Kratong started off in Sukhothai, but is now celebrated throughout Thailand, with the festivities in Chiang Mai and Ayutthaya being particularly well known.
