30 Days is a reality television show on the FX cable network in the United States, created and hosted by Morgan Spurlock. In each episode, Spurlock, or some other person or group of people, spend 30 days immersing themselves in a particular lifestyle with which they are unfamiliar (e.g. working for minimum wage, being in prison, a Christian living as a Muslim etc.), while discussing related social issues.
As in Spurlock’s film, Super Size Me, there are a number of rules unique to each situation which must be followed during each such experiment. At least one episode each season has featured Spurlock as the person spending the month in the particular lifestyle.
