Through 2014, Speedweeks informally kicked off in early January with off-season testing at Daytona. The NASCAR Sprint Cup Series and Xfinity Series regularly conducted annual preseason tests on the 2.5 mi (4.0 km) oval, under the moniker "Preseason Thunder". For 2015, the January test sessions were cancelled as part of NASCAR's overall ban on private testing.
24 Hours of Daytona
The first major event of Speedweeks is the Rolex 24. Currently it is held the final weekend of January, which is also the bye week for the Super Bowl. This weekend has been specifically chosen to avoid conflict with the Super Bowl. Events during the weekend include:
Daytona 500 week
Following the Rolex 24, there is no track activity for two weeks. This prevents a conflict with the Super Bowl. During this time, track officials clean the track, convert it back to the oval configuration, and make final preparations for the arrival of stock cars and the increased number of spectators.
The highlight of Speedweeks are the nine days leading up to and including the Daytona 500. It begins the weekend prior to the Daytona 500, and ends with the race itself. Currently, the Daytona 500 is scheduled for the Sunday of the weekend during the Presidents Day holiday.

In 2005, a 5K run was added to the Speedweeks schedule, as part of the Rolex 24.
In 2007, the IndyCar Series hosted an open test on the road course configuration during the week after the Rolex 24. No race was scheduled, however.
