For the first time in Indy history, the race was scheduled for the Sunday of Memorial Day weekend. This ended the "never on a Sunday" policy previously held from 1911 to 1973. At the time, it was also the earliest calendar date (May 26) that the race had ever been held. With the implementation of the Uniform Monday Holiday Act in 1971, the holiday was now observed on the last Monday of May (25–31), creating a three-day weekend (Saturday–Monday) every year.
