The Formula One calendar has been revised, pushing races in Turkey, Mexico and Brazil back by a week.

Formula One announced the changes on Saturday with the Turkish Grand Prix, originally slated for Oct. 3, now being held Oct. 10.

Although the United States GP stays on Oct. 24, the Mexican GP has been moved from Oct. 31 to Nov. 7, with Brazil shifted from that date to Nov. 14.

There is set to be a race the following weekend, but the location has yet to be given amid reports it could be Qatar, given that the season concludes with the inaugural Saudi Arabian Grand Prix at Jeddah on Dec. 5 as the penultimate race followed by the season-ending Abu Dhabi Grand Prix on Dec. 12.

The changes were triggered by the cancelation of the Japanese GP on Oct. 10 amid coronavirus concerns.

"The pandemic continues to present the season with challenges, but we have proven we can adapt, and we are confident we can deliver a record-breaking 22 races this year," F1 president Stefano Domenicali said. "I want to thank the promoters in Brazil, Mexico and Turkey for their patience and flexibility."

The cancelation and postponement of races last year at the start of the pandemic meant the 2020 season didn’t start until July and that it was compressed to a 17-race schedule through December.
