On this day, the entire island of Bali will come to a complete standstill. To allow all to follow the prescribed ritual, all traffic all over Bali will be stopped. No planes will land or take off for 24 hours. All shops are closed. No one is allowed on the beach or on the streets. There will be local watchmen known as pecalang to ascertain that this rule is obeyed. At night, all lights will have to be turned off. Hotels will close all curtains that no ray of light shines to the outside. All sound and music indoors should be held to its lowest volume.
