The Martian calendar used in this simulation is based on Shaun Moss's "Areosynchronous Calendar". http://pweb.jps.net/~gangale3/moss/Virtual_Mars/Calendar.asp (http://pweb.jps.net/~gangale3/moss/Virtual_Mars/Calendar.asp)
The Areosynchronous Calendar is heavily derived from Tom Gangale's Darian Calendar. http://pweb.jps.net/~tgangale/mars/mst/darian.htm (http://pweb.jps.net/~tgangale/mars/mst/darian.htm)
The Martian year is referred to as an "orbit". It is 668.5921 Martian days ("Sols") long. In the calendar, about half of the orbits are 668 Sols long, and the other half are "leap-orbits" with 669 Sols. See the Areosynchronous Calendar for complete details on leap-orbits.
The orbit has 24 months with either 27 or 28 Sols:
Month Name Sols

Adir 28

Deti 28
Edal 28

Safundo 27
Tiunor 28
Ulasja 28
Vadeun 28
Wakumi 28
Xetual 28
Zungo 27 or 18 if a leap-orbit
The month names are based on Frans Blok's "The Rotterdam System". http://www.geocities.com/fra_nl/rotmonth.html (http://www.geocities.com/fra_nl/rotmonth.html)
There are seven sols in a Martian week with the following week names:
Heliosol Neriosol Libersol Terrasol Venusol Mercusol Jovisol
Every Martian month has 4 weeks. On months with 27 Sols, the last week only has six Sols and Jovisol is clipped. This allows the first Sol of every month and every orbit to be Heliosol.
The calendar uses metric time for Mars with the Sol broken up into the following common units:
decasol = 1/10 Sol = 2.46 Earth hours centisol = 1/100 Sol = 14.8 Earth minutes millisol = 1/1000 Sol = 1.48 Earth minutes
Martian time of the Sol is usually written in three-digit millisol format to three decimal points. ex. from "000.000" to "999.999".
The common timestamp format for Mars date/time is orbit-month-sol:millisols. ex. "17-Adir-03:523.234"
The time of the day is based on Bruce Mackenzie's "Metric Time for Mars". http://pweb.jps.net/~gangale3/other/mcknzfrm.htm (http://pweb.jps.net/~gangale3/other/mcknzfrm.htm)
