How many months is there in a mars year?
Mars does not, as such, have any months as there is no-one on mars to need them. Compared to the earth, Mars takes 1.0259567565 days (24 hours 37 minutes 22.66376 seconds) Compared to earths rotation: 0.9972696323 days (23 hours 56 minutes 4.0962 seconds) The fact that Earth and Mars rotations are so similar you could just say they have the same 12 months, but you can’t say that this is a fact.
