The Premier League is a professional association football league in England and the highest level of the English football league system. Contested by 20 clubs, it operates on a system of promotion and relegation with the English Football League (EFL). Seasons usually run from August to May, with each team playing 38 matches: two against each other team, one home and one away. Most games are played on weekend afternoons, with occasional weekday evening fixtures.
The competition was founded as the FA Premier League on 20 February 1992, following the decision of clubs from the First Division (the top tier since 1888) to break away from the English Football League. Teams are still promoted and relegated to and from the EFL Championship each season.
