Date changes: The Houston Open was moved back six months, from April to October. The Greenbrier Classic was moved back two months, from July to September. Due to the scheduling changes, neither tournament had been on the 2018–19 schedule. The 3M Open moved back three weeks, from early July to late July. The Sanderson Farms Championship moved up five weeks, from late October to mid September. The Shriners Hospitals for Children Open moved up four weeks, from early November to early October. The Rocket Mortgage Classic moved up four weeks, from late June to late May. And the tandem of the WGC-FedEx St. Jude Invitational and Barracuda Championship moved up three weeks, from late July to early July to accommodate the 2020 Summer Olympics.
There are also a number of events which are recognized by the PGA Tour, but which do not count towards the official money list. Most of these take place in the off season (November and December). This slate of unofficial, often made-for-TV events (which have included the PGA Grand Slam of Golf, the Wendy's 3-Tour Challenge, the Franklin Templeton Shootout, the Skins Game, etc.) is referred to as the "Challenge Season" or more commonly as the "Silly Season."
PGA Tour players compete for two player of the year awards. The PGA Player of the Year award dates back to 1948 (originally named the PGA Golfer of the Year) and is awarded by the PGA of America. Since 1982 the winner has been selected using a points system with points awarded for wins, money list position and scoring average. The PGA Tour Player of the Year award, also known as the Jack Nicklaus Trophy, is administered by the PGA Tour and was introduced in 1990; the recipient is selected by the tour players by ballot, although the results are not released other than to say who has won. More often than not the same player wins both awards; in fact, as seen in the table below, the PGA and PGA Tour Players of the Year have been the same every year from 1992 through 2018.
The number of Race to Dubai points available in the last three events of the season was increased, and the field size reduced. The aim was to make more players still have a chance of winning the Race to Dubai entering the final events. In addition, although the prize money was not increased, the bonus pool of US$5m would now be split among the top five players rather than the top ten. The money saved from restricting field sizes was used solely to increase the first prizes, which means that the tournaments would not have the standard prize fund distribution, and the DP World Tour Championship, Dubai would have the largest tournament first prize in golf of US$3m.
