Calendar
At the annual press conference during the 2018 24 Hours of Spa on 27 July, the Stéphane Ratel Organisation announced the first draft of the 2019 calendar. Kyalami was added to the schedule. On 3 December, it was announced the nine-hour race in South Africa would be moved from 3 to 23 November to avoid a clash with the Rugby World Cup. The date of the California 8 Hours was confirmed on 18 January. The race was moved from Sunday to the Saturday the day before in order to better accommodate live TV. {{legend|#DFFFDF|Also part of the Blancpain GT Series Endurance Cup|border=solid 1px #AAAAAA}}
