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."
Most members of the tour play between 20 and 30 tournaments in the season. The geography of the tour is determined by the weather. It starts in Hawaii in January and spends most of its first two months in California and Arizona during what is known as the "West Coast Swing" and then moves to the American Southeast for the "Southern Swing." Each swing culminates in a significant tour event. In April, tour events begin to drift north. The summer months are spent mainly in the Northeast and the Midwest, and in the fall (autumn) the tour heads south again.
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.
