When the lights go out and racing starts at Sunday's Austrian Grand Prix, it will have been 217 days -- or 31 weeks -- since the chequered flag last fell on a Formula One championship event.
The coronavirus pandemic delayed the 2020 season by nearly four months from its original starting point -- the Australian Grand Prix in March -- but has also forced F1 into some radical decisions it might not have made otherwise.
Austria's race is the first of eight confirmed events we have to kick-start the new season, although F1 hopes to expand that schedule to 15-18 races in the coming weeks.
It is remarkable how much has happened since we last went racing -- F1 arrives in Austria with some fundamental differences from the sport that left Abu Dhabi in December. Here's everything that has happened in the seven long months without a grand prix.
Dec. 1: Ferrari is summoned to the stewards following the Abu Dhabi Grand Prix. The news reignites controversy over the Italian team's engine, which had lingered through the year.
After the investigation of Charles Leclerc's car, Ferrari is fined 50,000 Euros for a fuel irregularity, but Leclerc is not thrown out of the race and holds on to third position at the 2019 season finale.
At the same time, Lewis Hamilton acknowledged a recent meeting with Ferrari president John Elkann. Over the Abu Dhabi GP weekend, rumours of a Hamilton-Ferrari deal gathered pace.
Speaking after winning the race, Hamilton said: "I love where I am, so it's obviously not a quick decision to go do something else, but I think it's only smart and wise for me to sit and think of what I want and if it is the last stage of my career."
Dec. 5: Ferrari collects some Formula One silverware as Italian gamer David Tonizza claims the esports F1 Pro Series championship.
Dec. 6: Hamilton picks up his sixth world championship trophy at the FIA's Prize Giving Gala. He calls 2019 the best racing season of his life.
Hamilton also hints that Max Verstappen, who was also at the gala, had been calling Mercedes boss Toto Wolff for a future contract.
"It's an interesting time because there are lot of drivers who are seeking positions everywhere," Hamilton said. "The amount of calls that Toto gets from drivers -- including the one that was up here just recently -- asking to come, everyone's thing [is] to leave their team to come to where we are."
The same day, Renault confirms the departure of technical director Nick Chester, following a difficult campaign that saw the French manufacturer finish behind engine customer McLaren.
Dec. 7: Williams confirms W Series' inaugural champion Jamie Chadwick will remain in its driver academy for 2020.
Dec. 10: Formula One teams unanimously vote to reject Pirelli's prototype 2020 tyre, opting instead to stay with the constructions used in 2019. Drivers had been largely unimpressed with the 2020 prototype during the two-day tyre test that followed the Abu Dhabi Grand Prix.
Dec. 13: McLaren's Lando Norris is named Rookie of the Year for 2019, beating Red Bull's Alexander Albon and Williams' George Russell with a whopping 76% of the fan vote.
Ferrari boss Mattia Binotto also confirms the Italian team is looking to add a female driver to its academy lineup.
"Women should be part of the Ferrari Driver Academy," Binotto said. "That's something we are working right now to make sure that it will happen very soon. Ferrari is always investing in the future to make sure that we can be stronger and stronger over the medium and long term."
Dec. 18: Williams signs British driver Dan Ticktum to a development role.
Dec. 23: Leclerc is rewarded for his stellar first season at Ferrari with five-year contract extension. The news raised speculation about the future of Sebastian Vettel, who was set to enter the final year of his contract in 2020.
Jan. 1: Robert Kubica joins Alfa Romeo as reserve driver
After being dropped by Williams after his deflating 2019 comeback year, Kubica ensured he will stay affiliated to Formula One by taking on the reserve driver role at Alfa Romeo. Kubica's sponsor ORLEN went with him to the Swiss team.
Jan. 7: Verstappen signs a three-year Red Bull contract extension, one that extends beyond Honda's existing commitment to the team. It is not only a ringing endorsement of the team's F1 project, but it also takes the Dutchman off the driver market for the foreseeable future.
Jan. 10: The FIA launches e-karts launched to answer Lewis Hamilton's call for greater diversity in racing. The initiative will be run by former Ferrari and Williams engineer Rob Smedley.
"As Lewis Hamilton himself said recently: racing has become too expensive and is not diverse enough," Smedley said at the time. "I totally agree. Through electrification we can change that. We will be the driving force to inspire, energise and thrill racers as they climb the ladder. It is cleaner, cheaper, faster and importantly, fairer."
Jan. 15: Williams signs Israeli driver Roy Nissany to a reserve role for the coming season. Nissany's role means he is on standby to replace Russell or Nicholas Latifi if either is unable to compete at a race weekend.
Jan. 17: Ferrari adds Leclerc's younger brother, Arthur, to its driver academy. Arthur joins an academy including Mick Schumacher, son of seven-time world champion Michael, Enzo Fittipaldi, the grandson of two-time world champion Emerson, and Giuliano Alesi, son of French former Ferrari driver Jean.
Jan. 20: F1's commercial boss, Sean Bratches, announces he will be stepping down from his position at the end of the month. Bratches joined F1 from ESPN with Liberty Media's takeover at the beginning of 2017.
Jan. 29: Fernando Alonso says he has his sights set on a Formula One return in the future as he has "unfinished business" with the sport. The Spaniard's McLaren affiliation had officially ended at the end of 2019.
Jan. 30: Motor racing's governing body, the FIA, confirms it is monitoring the threat of COVID-19 on the Formula One and Formula E seasons. It is the first public statement on the flu-like virus, which originated in China.
Jan. 31: Racing Point confirms it will become Aston Martin from 2021 onwards. The news followed Canadian billionaire Lawrence Stroll, father of Racing Point driver Lance, purchasing up to 20% of Aston Martin. Reports suggest Stroll paid £182 million for a 16.7% stake, which could rise to 20%.
Feb. 4: British driver Jack Aitken joins Williams in a development role. The move bolsters Williams' roster further -- Aitken joins Ticktum and Chadwick in behind-the-scenes roles for the F1 team.
Feb. 6: Haas offers the first glimpse of a 2020 car, releasing a rendering of the VF-20. The American team's car featured a move back to its traditional colours of Gene Haas' company following its split with title sponsor Rich Energy in 2019.
Feb. 10: At the launch of Mercedes' 2020 car livery, Wolff says Mercedes and Hamilton remains an "obvious pairing" for the team's immediate future.

Feb. 14: McLaren unveils its car for the new season.

Mercedes also completes the first laps with its 2020 car at Silverstone.
Feb. 16: Racing Point reveals the first images of its pink livery.
Feb. 19-21: Alfa Romeo unveils its car in the pit lane on the opening morning of preseason testing. Sebastian Vettel misses the test for Ferrari as he is feeling unwell. The first test continues through to Feb. 21.
The item that creates the biggest stir in the opening week is Mercedes' dual-axis steering (DAS), which allows Hamilton and Valtteri Bottas to adjust the alignment of the front wheels from the cockpit -- something that was previously possible only when the car was stationary in the garage. The system is controlled by the driver either pulling or pushing the steering wheel while they are driving in a straight line.
Feb. 26-28 Teams complete the three days earmarked for the second and final preseason test in Barcelona. While Mercedes remains quickest, an engine issue for Hamilton on the second day of this test raises speculation of underlying reliability issues with the world champion's car.
What causes the biggest stir this time around, however, is not on a car, but rather an FIA statement that it had reached a private settlement with Ferrari over its 2019 engine. No further details into the investigation are released.
March 3: Formula One's head of motorsport, Ross Brawn, insists the sport will not race on if one of its team is unable to compete due to a case of coronavirus. Despite fears about the global spread of COVID-19, F1 heads to Australia for the opening race.
March 4: Seven of F1's 10 teams -- everyone except Ferrari and its two engine customers, Haas and Alfa Romeo -- unite to threaten the FIA with legal action if "full and proper disclosure" is not given about the FIA-Ferrari engine settlement. The statement questions the governing body's transparency and integrity.
March 5: Following the statement of the day before, the FIA offers clarification on the Ferrari engine settlement.
Its statement said: "The extensive and thorough investigations undertaken during the 2019 season raised suspicions that the Scuderia Ferrari PU could be considered as not operating within the limits of the FIA regulations at all times. The Scuderia Ferrari firmly opposed the suspicions and reiterated that its PU always operated in compliance with the regulations.
"The FIA was not fully satisfied but decided that further action would not necessarily result in a conclusive case due to the complexity of the matter and the material impossibility to provide the unequivocal evidence of a breach."
