During the early Rattanakosin period, the royal rituals of Jong Priang, Lote Choot, Loi Khome Long Nam, performed during the twelfth lunar month were based on Brahmin beliefs. These were the court versions of Loi Krathong performed as an act of worship in which the Devaraja or ‘God Kings’ made offerings of light to the Brahmin deities. Lit lanterns were hoisted on to poles for two weeks during the twelfth lunar month and then floated on the waterways as ritual offerings. From its Brahmin roots, the practice has evolved over time and has come to be part of a Buddhist ritual performed as an act of deep reverence and worship of the sacred relics and holy footprints of Lord Buddha.

The practice was subsequently adopted and adapted by common folk. Krathong floats are made from basic materials easily found around the village and reflect the simplicity of life beyond the palace walls. They typically take the shape of lotus in full bloom, swans, chedis (stupas), and Mount Meru from Buddhist mythology. However krathong floats in the shape of lotus blossoms are most popular.

At dusk, as the full moon begins to rise, the krathong is decorated with fresh flowers and the candles and incense sticks are placed in the krathong. The float is then taken to a waterway where the candle and incense sticks are lit and the krathong set adrift. The floats are carried downstream by the gentle current, candlelight flickering in the wind.

Soon after, attention turns to celebration. The evening's festivities consist of impressive firework displays, folk entertainment, stage dramas, song and dance. Scenes as described in ancient Thai literary accounts are still very much in existence today.

Krathong floats in the shape of lotus blossoms are most popular and are made from materials easily found in each locality. Loi Krathong customs and traditions reflect local beliefs and cultural evolution and interesting regional variations can be seen.
