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. Indycar events in square brackets are ‘doubleheader’ events, 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 WEC and USCC both have races at Austin that are dated according to their web-sites on the Saturday, but I expect the WEC will race on Sunday. The USCC date given for Indianapolis is actually for the Friday, maybe because they will utilise the road-course, with NASCAR then using the oval. Indycar will race on the Indianapolis road-course two weeks before the ’500.
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.
