The Premier League is an English professional league for men's association football clubs. At the top of the English football league system, it is the country's primary football competition. Contested by 20 clubs, it operates on a system of promotion and relegation with the Football League. Besides English clubs, some of the Welsh clubs can also qualify to play, and participation by some Scottish or Irish clubs has also been mooted.
The Premier League is a corporation in which the 20 member clubs act as shareholders. Seasons run from August to May, with teams playing 38 matches each, totalling 380 matches in the season. Most games are played in the afternoons of Saturdays and Sundays, the other games during weekday evenings. It is currently sponsored by Barclays Bank and thus officially known as the Barclays Premier League. Outside of the United Kingdom it is commonly referred to as the English Premier League (EPL).
