At first, the World Athletics Championships in the United States were scheduled for 6-15 August 2021, but have been pushed back to 2022 to avoid a clash with the Tokyo Olympics.
World Athletics also said the new schedule for 2022 will prevent a direct conflict between multi-sport European Championships and Commonwealth Games.
"In an extraordinary international season for athletics, all three events will be held across an unprecedented summer of sport. The World Championships will begin a unique celebration of the sport, followed by the Commonwealth Games and the European Athletics Championships as part of the European Championships." the World Athletics said.
"This will be a bonanza for athletics fans around the world," World Athletics president Sebastian Coe said.
The 2022 Birmingham Commonwealth Games are scheduled from 27 July to 7 August, with the multi-sport European Championships, beginning on 11 August in Munich, Germany, with the track and field events beginning on 15 August.
"They will be treated to six weeks of absolutely first-class athletics. More than 70 of our Member Federations are part of the Commonwealth and more than 50 of our Member Federations are European so our guiding principle in rescheduling the World Championships was to ensure enough space was created around the centrepiece World Athletics Championship for athletes to choose other major events to compete in. We were also very mindful that we did not want to damage the other major championships in 2022, because they are also very important to our sport."
