All dates listed are Sundays with races that start on the Saturday in brackets; apart from WRC events which finish on the Sunday, except those in brackets which finish on Saturday. The Detroit round of Indycar events is a double-header with races on both Saturday and Sunday. The two NASCAR events that are starred are non-championship races, being the Sprint Unlimited at Daytona and the All-Star event at Charlotte. USCC races feature far too many complications in formats from round to round to indicate.
The column headings are also at the bottom of the table, which helps with viewing the lower half. The table is an image, so can be right-clicked and saved.
