The "sidereal day" and the "sidereal year".
The sidereal day is the time taken for Earth to rotate once, measured against the background of stars.
Stars are very distant, so it means we get an accurate measure of the rotation time.
The day of 24 hours is based on Earth's rotation relative to the Sun. That doesn't give the "true" rotation time, but it's very convenient in daily life, of course.
