Participants must first raise money through sponsorship from other people. Participants must then abstain from a particular group of items or do/not do something for 40 hours. Some of the famines include not eating food, not using first world technology such as television, refraining from talking, and not using furniture. Some participants create their own famines, such as living in a cardboard box or being blindfolded. The event officially runs from 8 pm on Friday to noon on Sunday, usually over a weekend in August. Participants may choose another time to fast if the official famine dates do not suit them.
