The Masters - which had been due to take place this week - has been pencilled in for mid-November as golf adjusts to the coronavirus.
With the Open Championship now cancelled, it has been confirmed that the other three majors remain on the calendar with the Masters due to take place from November 12-15.
The PGA Championship, held this year at Harding Park in California, is now scheduled for August 6-9 - a date which seems likely to require further adjustment - with the US Open in New York put back to September 17-20.
The Ryder Cup remains in its original slot, now one week on from the US Open, while the final four events of the PGA Tour season have been put back by a single week.
Current schedule highlights for 2020
- The Open - Cancelled
- PGA Championship - August 6-9
- TOUR Championship - September 4-7
- US Open - September 17-20
- Ryder Cup - September 25-27
- The Masters - November 12-15
While the date of the PGA Championship may appear the most ambitious - it's just three weeks on from the original dates of the Open - the US Open may be no more likely to take place, given that New York state has been hit hardest by the pandemic.
The Masters, however, is now seven months away, conditions in Georgia dictating that only a post-summer slot would work. That slot has been found, meaning there now could be two renewals in the space of five months.
"In collaboration with the leading organisations in golf, Augusta National Golf Club has identified November 9-15 as the intended dates to host the 2020 Masters," read a statement from Augusta chairman Fred Ridley.
"While more details will be shared in the weeks and months to come, we, like all of you, will continue to focus on all mandated precautions and guidelines to fight against the coronavirus.
"Along the way, we hope the anticipation of staging the Masters Tournament in the fall brings a moment of joy to the Augusta community and all those who love the sport."
On the new dates for the Masters, US Open and PGA Championship, US PGA chief executive Seth Waugh said: "We will continue to follow the guidance of public health officials, but are hopeful that it will be safe and responsible to conduct the PGA Championship in August and the Ryder Cup as planned from September 22-27 at Whistling Straits in Kohler, Wisconsin."
