Buddhist Lent Day (Thailand Wan Khao Phansa, Laos Boun Khao Phansa) is the start of the three-month period during the rainy season when monks are required to remain in a particular place such as a monastery or temple grounds. Here, they will meditate, pray, study, and teach other young monks. In the past, monks were not even allowed to leave the temple, but today, most monks just refrain from traveling during this period. You will still see them out during the day.
It is said that monks started remaining immobile in a temple during this time because they wanted to avoid killing insects and harming farmland. Apparently, traveling monks were crossing through fields, thus destroying the crops of villagers and farmers. After catching wind of this, Buddha decided that in order to avoid damaging crops, hurting insects, or harming themselves during the rainy season, monks should remain in their temples during these three months.
