One year on Mars about 687 Earth days.
That's about 1.88 Earth years.
The length of a sidereal year on Mars is about 686.98 Earth solar days (24 hours).

One Mars year is about 687 Earth days or 1,89 Earth year.
It takes Mars 687 Earth days for a complete rotation of the Sun (Just under 2 years).1 day on Mars is equal to 24 hours and 39 minutes on Earth (i.e. A Mars day is 39 minutes longer than an Earth day!)
If you are speaking of one orbit around the sun, about 2 earth years. If you are using Earth's calendar, one year is one year. (note it's rotation on it's axis is a little more than one Earth day - 24.6 hours) on mars there is only a little time difference if compared to the earth if on earth 7:00AM than on mars it will be 7:10AM!!
one earth minute = one mars minute in other word, one minute is one minute everywhere in the universe, same as one second. but one earth day would be different from one mars day as the we use the time it take the earth to finish one rotation as one earth day.
One year on Mars is approximately 687 Earth days long. A day on Mars, known as a sol, is about 24 hours and 39 minutes. This means a year on Mars is almost twice as long as an Earth year in terms of days.
A day on Mars (the time it takes to rotate on its axis) is 24.62 hours, just slightly longer than a day on Earth.A year on Mars (the time it takes to go around the Sun) is 686.97 days, almost 2 of our Earth years.for more information, See other related questions, e.g. how long is a day on mars?=]
Mars spins slower than earth
Mars' rotation is 24 hours, 39 minutes, and 35 seconds (solar day).
It takes about one earth day on mars. My estimate is probably 24 and a half hours in a day. A year takes about 687 earth days on mars.
No planet really does have a day "the same length as Earth", but Mars definitely has the one that's the closest. The day length of Mars is just over half an hour longer than Earth's.
Mars rotates on its axis (one sidereal day) with a rotation period of 1.0256 Earth days or 24.622 hours. Mars orbits the Sun in 686.971 Earth days or 1.8808 Earth years or 668.6 Martian days. Mars has to have a leap year every third year and subtract a day or add two days.
Mars receives about half the amount of sunlight in one Earth day compared to Earth. This is because Mars is farther away from the Sun and has a longer day, lasting about 24.6 hours.
