Chase Carey confirmed in a statement that Austria is now set to host the opening race on 5 July, with the following European races keeping their places on the calendar.
The 2020 Formula 1 season is yet to begin with the first nine rounds of races already cancelled due to the COVID-19 pandemic which has nearly brought the entire world into lockdown and killed more than two lakh people.
The French Grand Prix on Monday cancelled its race scheduled for June 28 rather than postponing it, making July 5 the targeted start date at the Austrian GP in Spielberg.
"We expect the early races to be without fans but hope fans will be part of our events as we move further into the schedule", Mr Carey said.
"We still have to work out many issues like the procedures for the teams and our other partners to enter and operate in each country".
Mr Carey said Formula 1 had been working closely with teams and promoters and a definitive calendar would be published as soon as possible.
That means the British, Hungarian, Belgian and Italian Grands Prix could all still go ahead on their original weekends, although fans would not be allowed to attend. "The health and safety of all involved will continue to be priority one and we will only go forward if we are confident we have reliable procedures to address both risks and possible issues".
Ruling out holding the race behind closed doors, Boullier said: "Le Castellet are already turning towards the summer of 2021".
The British Grand Prix has notified fans who purchased tickets for this year's event that any race held in 2020 will be without spectators.
However, the calendar after the Austrian GP remains very much in gray as the three following races at the Silverstone is unlikely to take place as scheduled due to the way the United Kingdom has been hit by the ongoing crisis.
In an interview with CNN, Racing Point F1CEO and Team Principal Otmar Szafnauer said that Formula 1 should have raced in Australia at the beginning of the season despite the concern of COVID-19.
"I am extremely disappointed to tell you that we are unable to stage this year's British Grand Prix in front of the fans at Silverstone", the circuit's managing director Stuart Pringle stated on Silverstone's Twitter account.
The British Grand Prix, however, is likely to take place without fans, after Silverstone's owners said a race "under normal conditions was just not going to be possible" due to the virus.
