One of the most popular festivals in early November is the Loy Krathong Festival. It takes place at a time when the weather is fine as the rainy season is over and there is a high water level all over the country.
There is a Buddhist myth that during one Rains Retreat or Khao Phansa Lord Buddha went to haven to deliver a sermon to his mother who died after giving birth to Lord Buddha (then Prince Siddharatha) and was born again in heaven.
Songkran is the Thai traditional New Year and an occasion for family reunion. At this time, people from the rural areas who are working in the city usually return home to celebrate the festival. Thus, when the time comes, Bangkok temporarily turns into a deserted city.
