The Formula 1 calendar is becoming increasingly crowded. Next year there are no less than 24 races on the calendar, this year the plan was also to hold 24 races, but due to flooding during the GP weekend in Imola, the Grand Prix there did not take place and also the Chinese GP was canceled for the fourth year in succession. As a result, there will be 'only' 22 races in 2023. Until when do all these circuits have a contract with Formula 1?
