The 2013 season, which was the last before the tour transitioned to a schedule spanning two calendar years, had 40 official-money events in 38 weeks, including three alternate events played the same week as a higher-status tournament. The other event that is considered part of the 2013 season is the biennial Presidents Cup, matching a team of golfers representing the US with an "International" team consisting of non-European players (Europeans instead play in the Ryder Cup, held in even-numbered years).
Finally, two events held in Asia after the end of the PGA Tour's current regular season – the CIMB Classic in Malaysia and the HSBC Champions, a World Golf Championships event held in China – became full PGA Tour events, with official prize money, for the first time. Before 2013, neither event had full PGA Tour status despite being sanctioned by the Tour. Wins in the CIMB Classic were not classified as official PGA Tour wins, and HSBC Champions victories were official wins only for current PGA Tour members. Money earned in these events did not count as official PGA Tour earnings for any purpose.
Invitational: These events are similar to the regular ones, but have a slightly smaller field and do not follow the normal PGA Tour exemption categories. Invitational tournaments include the Charles Schwab Challenge, the Arnold Palmer Invitational, the RBC Heritage, the Memorial Tournament. The tournaments usually have an association with a golf legend, or in the case of the RBC Heritage, a famous course. The table below illustrates some of the notable features of the exemption categories for these events:
