The season began on 4 August 2012 for The Football League, 11 August 2012 for the Football Conference and 12 August 2012 for the Premier League. The regular season of the Football Conference season ended on 20 April 2013 followed by League One and League Two both ending on 27 April 2013 whilst The Championship ended on 4 May 2013 and finally the Premier League on 19 May 2013.

In Sir Alex Ferguson's final season as manager, Manchester United comfortably won their 13th Premier League title and their 20th overall, topping the table in mid-November and never surrendering their lead, though a run of just three wins in their last eight matches meant that they squandered the chance to become the first ever top-flight side to earn a hundred points in a season. Neighbours and defending champions Manchester City finished in second place, though they never looked like seriously challenging for a second successive title, and this, combined with a humiliating FA Cup final defeat to Wigan Athletic, cost Roberto Mancini his job. Despite enduring a turbulent season in which Champions League-winning manager Roberto Di Matteo was dismissed early in the campaign and replaced by the extremely unpopular appointment of former Liverpool boss Rafael Benítez on an interim basis, Chelsea did improve on the previous season's finish by three places and 11 points, and also won the Europa League for the first time in their history. The final Champions League spot was taken by Arsenal; despite being well off the pace for much of the season following the £24 million departure of Robin van Persie in the summer, they managed to snatch fourth place with an excellent late run of form, consigning rivals Tottenham Hotspur to the Europa League once again.
