The Presidents Cup has been held biennially since 1994. Initially it was held in even-numbered years, with the Ryder Cup being held in odd numbered years. However, the cancellation of the 2001 Ryder Cup due to the September 11 attacks pushed both tournaments back a year, and the Presidents Cup was then held in odd-numbered years. It reverted to even-number years following the postponement of the 2020 Ryder Cup due to the COVID-19 pandemic. It is hosted alternately in the United States and in countries represented by the International Team.
