The inter-county season begins in January with each province's warm-up competition and ends in September with the All-Ireland final. The GAA's inter county competitions are the organisation's most attended competitions and are Ireland's most attended sporting events, while the All-Ireland finals are the most watched.[4] and the All-Ireland Football Final is the most watched event in Ireland's sporting calendar.[5]
The British Provincial Council organises inter-county competitions for the seven counties under its control on the island of Britain.[7] The British Provincial Council is the only area outside Ireland to organise regular inter-county matches.
Changing clubs between counties is known as an inter-county transfer and is regulated by the Provincial council if the clubs are in the same province, or by the central council of the GAA when the transferring between clubs in different provinces. A special transfer is available for students going on a J-1 visa, which allows a temporary transfer to Canada, New York or North America.[8]
