If Mars has seasons then wouldn't it have it's own time keeping system?

Earth is the only planet with calenders. Earth has many calenders. Leap Years occur in solar calenders such as the Gregorian Calender and Jullian Calender. Some of the Lunar calenders have entire months skipped during their own form of leap year.

Earth does not "have" a leap year. A year on Earth is approximately 365.25 days long. We humans use the leap year as way of accounting for that quarter of a day. That is why every four years we add an "extra" day. Other planets may have a very similar situation in terms of a "year" of time not being exactly divisible into a number of days.

The reason we have leap years is to compensate for the fact that it doesnt take exactly 365 days to orbit the sun. On other planets there orbits are measured relative to one earth year and it doesnt matter if this is an awkward number such as 3 years 23.424999 days to orbit.

We only need it to make our calendar work with the seasons. On Mars and other planets, they don't have a need for a calendar. No one lives there that we know of.
