UN resolution established the International Day of Peace in 1981 to coincide with the opening of the UN General Assembly. The first Peace Day was celebrated in 1982 and was held on the third Tuesday of September each year until 2002, when September 21 became the permanent date for the International Day of Peace. The assembly decided in 2001 that the International Day of Peace should be annually observed on September 21 starting from 2002. By setting a fixed date for the International Day of Peace, the assembly declared that the day should be observed as a day of global ceasefire and non-violence.

By creating the International Day of Peace, the UN devoted itself to worldwide peace and encouraged people to work in cooperation for this goal. Since its inception, Peace Day has marked personal and planetary progress toward peace. It has grown to include millions of people worldwide and many events are organized each year to commemorate and celebrate this day.

To mark the day PCoE Rover Scouts also took part in the celebration of the day along with the schools under Paro Dzongkhag. Various programs like pledge taking and door to door campaign, cleaning campaign and peace message delivering competition are conducted by the Dzongkhag Scouts association in collaboration with Paro Youth Centre.
