The 2021 inter-county season will begin with Allianz Hurling League action on 8 May.
The Allianz Football League will begin a week later on the weekend of 15-16 May with the provincial championships commencing at the end of June.
All details of the revised updated fixtures programme were given by the GAA at a virtual meeting on Thursday afternoon.
The association stated that the objective of the revised plan was to give sufficient games at inter-county level and have inter-county completed by August so that a proper club window could be implemented.
In their original programme there were 27 weeks of games – that has been reduced to 20 as the association adapts to prolonged and ongoing Covid-19 restrictions.
Significantly, the All-Ireland Hurling Championship final will be played on the weekend of 21-22 August whilst the football final will take place on the weekend of 28-29 August.
Club action will begin on the first weekend of September.
There will be a return to collective training commencing on 19 April. Four counties have already been found to have begun collective training, with two disciplined and two more awaiting punishment.
As of yet, there are no return to activity dates for collective inter county minor or under-20 training as the GAA is awaiting further instruction from Government and current exemptions relate only to senior level.
There will be a minimum of five games for each senior county football and hurling teams this season.
Indeed, in hurling, all bar three counties are guaranteed six games.
In hurling London and other English teams will not be participating in this year's series, nor will New York in the football championship.
Allianz Football League
The football league commences from 15-16 May and runs until potential finals on 19-20 June.
