686.971 Earth days in fact.
Edit: That number looks like the time, in Earth days, for Mars to orbit the Sun. Maybe that helps.

Mars
A year on Mars is almost twice as long as a year on Earth, being 686.9726 Earth days long. However, this would be in 24 hour "Earth days", which are about forty minutes shorter than the Martian solar day. A Martian year is about 668.6 Martian solar days. (That is about 1.88 Earth years.) A solar day, or 'sol', is how long it takes the Sun to return to the meridian, and it varies slightly each day: the average length is 24 hours 39 minutes and 35 seconds.
It takes exactly 686 days 18 hours 12 minutes and 12 seconds for Mars to orbit the Sun. Or in 686.971 days
a day on mars is 24 hours, 39 minutes and 35 seconds compared to earth.
