The pattern of seven-day weeks repeats over a two-year cycle, i.e., the calendar year always begins on a Sunday in odd-numbered years, thus effecting a perpetual calendar for Mars. [ 27 ] Whereas previous proposals for a Martian calendar had not included an epoch, American astronomer I. M. Levitt developed a more complete system in 1954.
The Clancy Mars year is reckoned from one Martian northward equinox to the next (L s = 0°), and specific dates within a given year are expressed in L s. The Clancy Mars year count is approximately equal to the Darian year count minus 183. The Allison Mars sol date epoch equates to L s = 276.6° in a year that is undefined in the Clancy Mars ...

Mars Year 1 started on 11 April 1955 and ended on 25 February 1957. [2] Mars Year 1 is preceded by ...
A Martian year is approximately 668.6 sols, equivalent to approximately 687 Earth days [1] or 1.88 Earth years. The sol was adopted in 1976 during the Viking Lander missions and is a measure of time mainly used by NASA when, for example, scheduling the use of a Mars rover .
