With the new winter scheduling format, the series began at Silverstone Circuit in September 2019 and ended with the 2020 8 Hours of Bahrain in November 2020.

[1] After Formula 1 announced their provisional 2019 schedule, the WEC moved the Fuji round forward one week to 6 October to avoid a conflict with the Japanese Grand Prix.

The FIA also moved the date back three weeks to avoid a clashing with Super Bowl LIV and the Mexico City ePrix.

[3] The 1000 Miles of Sebring was scheduled for 20 March 2020, but was cancelled due to a travel ban to the U.S. from mainland Europe in response to the COVID-19 pandemic.

[6] On 3 April 2020, a new revised calendar for the 2019–20 season was released, with the Spa race moved to 15 August and another 8 Hours of Bahrain event, on 21 November 2020, replacing the cancelled 1000 Miles of Sebring.

[7] The final round at Bahrain in November was moved up a week as a result of Formula One scheduling a double header event at that venue for the end of the month.

A single bonus point was awarded to the team and all drivers of the pole position car for each category in qualifying.
