September:
That marks the end of the monks' three-month-fast and retreat during the rainy season. At dawn, donations and offerings are made at the temples. Prayers are chanted by the monks, and at dusk candlelight processions wind round the temples. Concurrently, hundreds of decorated candlelit-floats, made of paper, are set adrift in the rivers. These carry offerings and incense, transforming the river into a fragrant snake of sparkling. This ceremonial part is called Boun Lay Heua fai. The biggest event of the Phansa festival, Boun Souang Heua, is a boat race on the Mekong River between competing communities the next day.
