The length of the break has also been increased from two to three weeks in light of the current situation.
By moving the summer break, Formula 1 could theoretically stage three extra races in the month of August, though a triple or even quadruple-header is likely should those plans materialise.
Talks are reportedly underway to have the beginning of the season take place in May, with the Monaco Grand Prix staging the first race.
Four races – in Australia, Bahrain, Vietnam and China – have already been postponed. The Dutch and Spanish Grands Prix, scheduled for early May also look doubtful.
F1 is aiming to get the 2020 season underway in late May, though that date could be pushed into June and the Azerbaijan Grand Prix could be the curtain-raiser instead.
