The event always takes place in July and this is the start of the monsoon season and the weather causes more leaves and debris to fall from the trees so it’s easier for insects underneath to be accidently stepped on. Killing is to be avoided by all monks so this is why they don’t go outside the compounds and remain inside to study and practice meditation.
The start of the event is determined by the moon and this year will start on 16th July 2011. People staying in Khao Lak hotels during this time can visit one of the nearby temples and observe the people giving offerings to monks who rely purely on outside donations.
