As you probably know, most NASCAR Sprint Cup Series night races begin at 7:30 p.m. Eastern time.
That's part of NASCAR's initiative to standardize start times – 1 p.m., 3 p.m. and 7:30 p.m. – so fans are more familiar with when to tune in and watch.
But Darlington is different. The Southern 500 will begin shortly after 7 p.m. this year, in part because it allows fans who drove several hours to get back home sooner.
Darlington has more of a local crowd than many other tracks, so the extra 30 minutes might be the difference between getting home at 12:30 a.m. or 1 a.m.
That might not seem like much, but when fans are driving late at night after a long day, it can add up.
Here's a look at the complete NASCAR schedule for the next two days at Darlington Raceway (Note: All times are EASTERN):
8:30 a.m. – Nationwide Series final practice (two hours)
11:30 a.m – Sprint Cup Series practice (two hours)
2:15 p.m. – Sprint Cup Series final practice (45 minutes)
3:35 p.m. – Nationwide Series qualifying
5:10 p.m. – Sprint Cup Series qualifying
7:15 p.m. – Nationwide Series race (147 laps, 200.8 miles)
7 p.m. – Sprint Cup Series race (367 laps, 500 miles)
