Calendar[]
The preliminary race calendar was published by the championship management on 13 November 2020.[16] A change from previous years is that in 2021, for cost-cutting reasons, two races will be held on a weekend instead of three, and the series will return to the Asian continent after a year of omission.[17] On 22 January 2021, the calendar was updated, postponing the Race of Hungary to 21–22 August and replacing the Race of Slovakia with the Race of Italy.[18] On 10 May 2021, it was announced that the Race of Portugal would be held at the Circuito do Estoril instead of the Circuito Internacional de Vila Real.[19] On 19 August 2021, three new rounds were announced as replacements for the races in the Far East.[20]
