The sidereal rotation period of Mars - one spin on its axis relative to background stars, is 24.623 hours. This is very similar to the earths sidereal rotation period.
Mars takes about 24.6 hours to complete one full rotation on its axis, which is slightly longer than an Earth day.
Mars spins on it's axis in a very similar time to an Earth day. It takes about 24.6 (24.6229) hours for Mars to spin on it's axis. That is about 1.025 earth days.
It takes about 24 hours and 37 minutes.
