2012 sees the first time that GP2 has merged its Asian and European events into one championship. The GP3 series remains exclusively Europe-based. Races are usually organised as support events to the F1 Grand Prix weekends at the same locations.

The dates shown for the GP2 and GP3 races of 2012 cover three days: typically, Friday consists of the practice and qualifying sessions, Saturday is the feature race and the Sunday is the sprint race.
