Songkran or water festival, Hindu calendar-based New Year festivals

Songkran is a term derived from the Sanskrit word, saṅkrānti (or, more specifically, meṣa saṅkrānti) and used to refer to the traditional Lunar New Year celebrated in Thailand, Laos, 

Cambodia, Myanmar, Sri Lanka, parts of northeast India, parts of Vietnam and Xishuangbanna, China. It begins when the sun transits the constellation of Aries, the first astrological sign in the Zodiac, as reckoned by sidereal astrology. It is related to the equivalent Hindu calendar-based New Year festivals in most parts of South Asia which are collectively referred to as Mesha Sankranti.

Songkran is the occasion for family re-unions, temple visits and annual house cleaning. People from Many countries observe the holidays by spending time with families and friends. Traditionally, they perform the Rod Nam Dum Hua ritual on the first day of Songkran, which is officially the National Elderly Day. During the ritual, young people would pour fragrant water into the elders’ palms as a gesture of humility and to ask for their blessings. 

The second day of Songkran is officially the National Family Day. Families would wake up early and give alms to the monks, and then ideally the rest of the day would be spent sharing quality family time together. An important religious ritual on Songkran is ‘Bathing the Buddha image’, in which devout Buddhists pour fragrant water over Buddha statues both at the temple and at home. More religious Thais would engage themselves in Buddhist ceremonies and merit-making activities throughout the holidays.

The Songkran celebration is rich with symbolic traditions. Mornings begin with merit-making. Visiting local temples and offering food to the Buddhist monks is commonly practiced. On this specific occasion, performing water pouring on Buddha statues is considered an iconic ritual for this holiday. 

It represents purification and the washing away of one's sins and bad luck. As a festival of unity, people who have moved away usually return home to their loved ones and elders. As a way to show respect, younger people often practice water pouring over the palms of elders' hands. Paying reverence to ancestors is also an important part of Songkran tradition.

The holiday is known for its water festival which is mostly celebrated by young people. Major streets are closed for traffic, and are used as arenas for water fights. Celebrants, young and old, participate in this tradition by splashing water on each other. Traditional parades are held and in some venues "Miss Songkran" is crowned. where contestants are clothed in traditional Thai dress.
