The following Grands Prix were scheduled to take place in 2010 : The provisional calendar was announced on 10 November 2009 . In case a circuit was not able to hold a scheduled Grand Prix , a reserve race would take place on the same day at the Motorland Aragón circuit . This was updated six days later , with a date change for the Czech round , moving one week forward . It was announced on 18 March 2010 that Aragón would be included on the calendar , at the expense of the Balatonring , due to the fact that construction work on the latter circuit could not be completed on time . On 19 April 2010 , it was announced that the Japanese Grand Prix would be moved from 25 April to 3 October , due to the disruption to air travel after the second eruption of the Eyjafjallajökull volcano in Iceland
