Superstar
didn't happen in a day..
when he dropped off Jada it was probably around 8 p.m. and when the movie ended the sun was starting to come up.
so technically it happened over a span of two days but it was within 24 hours.
depends on which calender. in ancient times a "day" was sunset to sunset and only the sun hours were used to track time, the night hours were only used in astrology. the "midnight" 24 hour days being the official "day" is a relatively recent phenomenon. some cultures still use sunset to sunset to measure a "day", even when they use 12 hour clocks and am and pm.

and since it hasn't been mentioned, the TV show 24 took place in 24 hours.
