The Bahrain Grand Prix is usually the third race on the Formula One calendar, apart from the 2006 season, when Bahrain swapped places with the traditional opener, the Australian Grand Prix, which was pushed back to avoid a clash with the Commonwealth Games. In , Bahrain was moved to the fourth race. For the season Bahrain was again the season opener and Formula One cars drove the full "Endurance Circuit" to celebrate F1's 'diamond jubilee'. For 2011 however F1 was set to return to racing on the original layout used between 2004 and 2009. The race was postponed and finally cancelled due to protests in the country but F1 returned to the track for the 2012 Bahrain Grand Prix. 2014 saw the track host its first ever Grand Prix under lights, as the race was scheduled as a night race to celebrate the tenth year of Formula 1 at the circuit. Subsequent editions of the race have also been held at night. In 2020 the circuit hosted two Grands Prix, the Bahrain and Sakhir Grands Prix, after the calendar was revised following the COVID-19 pandemic with the second using an alternative layout.
