The GAA have formally adopted a split-season format from next year at Saturday's Congress meeting.
Delegates have strongly backed motion 12 at Congress, which paves the way for the All-Ireland inter-county finals to be played in July from 2022.
The second half of the year will be reserved for the club championships.
A motion on cynical fouling has also been added which is welcomed by new GAA president Larry McCarthy.
Delegates narrowly backed a sin bin in hurling this year as part of a crackdown on cynical play, which will also see penalties awarded in hurling and Gaelic football when a clear goal-scoring opportunity is denied.
The new playing rules are set to trialled in the upcoming National Leagues and McCarthy feels it's a positive step...
Possible changes to the format of the All-Ireland Senior Football Championship will be discussed at a Special Congress later this year.
