Bahrain Grand Prix organizers have confirmed that their 2012 event's move to an April date took place to allow the Indian GP to switch to later in the season.
The Sakhir race was originally listed as the 2012 season opener on 11 March, before a revised schedule was mooted in which Bahrain moved to the penultimate calendar slot - giving the country's political situation further time to settle after the issues that forced the cancellation of the 2011 grand prix.
This version of the calendar saw India's second Formula 1 race scheduled for April, but the Indian organizers were concerned that the weather would be too hot at this time of year. The final calendar, released on Wednesday, therefore sees India return to a late-October slot similar to its 2011 date, and Bahrain become round four on April 22 – a change that the Sakhir authorities said they were happy to accept.
"The Bahrain International Circuit has always worked in supporting the Formula 1 family and to do what is best for the sport," the group said in a statement. "We look forward to welcoming back all the teams, drivers, organisers, and fans in 2012."
