 If you are wondering why the sols on the clocks don't match the sols in the weather reports, the weather reports refer to mission time, rather than the start of the Martian year. Besides being a convenient way to track mission duration, it guarantees two data points in different years have unique sol counts.

 //[1] the calculation is based on data from the [[http://www.planetary.org/explore/space-topics/mars/mars-calendar.html|Planetary Society]], and divides the Martian year using the equinoxes and solstices. Further, it uses UTC to perform the calculations rather than Airy Mean Time (AMT), so is only an approximation to provide a rough guide. **AMT** is the Martian equivalent of GMT. The Martian year is 686.97 standard days (668.6 sols), approximately 1.88 years.//
