The Brazilian Football Confederation has announced the Série A schedule for the 2013 season.
The competition will start on Sunday, May 26, a week after the state leagues finals, and will feature 20 teams. Some games are likely to be moved to Saturday, May 25.
The league will be played until December 8.
As the Confederations Cup will be played in June, the Brasileirão will stop between June 9 and July 7.
The top four teams will qualify to Libertadores, while the bottom four are relegated to Série B.
A change in relation to 2012 is that there will not be any derbies on matchday 38, although those derbies were deemed useful to prevent clubs from losing on purpose to harm a rival.
The game between Santos and Flamengo will be played at the Mané Garrincha Stadium in Brasília, as a test event for the stadium, which is being renovated for the World Cup.
Current champions Fluminense debut against newly-promoted Atlético Paranaense.
These are the matchday one matches:
