Time zero of proleptic Martian calendar (as Julian Day Number): 451319.4767; (as Day Areocentric): Dar 0 (measured from 180 degrees West from Prime Meridian at local Midnight).

Equivalent Dar number to 15 August, 1999: 1,946,573

aphelic new Areon equivalent to 2 November 2000: 1947006 (start of Areon 2913)

cycles of solar calendar:

A. 9 areon indiction recovered from observation made of planetary conjunction and sun and moon from 119E/35W on 5 March 1953BC (nearest aphelion is 1007785.50770)

B. 45 areon rhodonic cycle (analogous to golden number wherein the order of the days of the week will not revert to initial condition until 28 years have passed). Based on average areon 668.6 Dar length, 669,668,669,669,668 which is based on anomalistic Martian areon of668.6141 dars of 88,775.244 seconds from calculations done by Michael Allison. Intercalation every 70 areons will keep calendar accurate to one dar in 5000 areons. The cycle is based on a time line from the first observation of the surface features of Mars by Huygens on 28 November 1659. That mark would have been the first day which 1 assign to Mercury because it is information. The first Dar of that Areon would be assigned to Neptune which is the 30th areon of the rhodonic cycle. Dars are ordered according to the structure of terrestrial astrological calendars, except there are 9 celestial objects in order: Pluto, Neptune, Uranus, Saturn, Jupiter, Sun, Earth, Venus and Mercury. The order of the dar is recovered by assigning a regnal number to each period of a 25 hora dar (or centidar) as proposed by Bruce Mackenzie. Which makes the first dar of a 9 Dar period (Phobon) Pluto, followed by Venus, Sun, Saturn, Neptune, Mercury, Earth, Jupiter and Uranus.

C. Geonic cycle, which is Mars/Earth at closest distance (perigeon) over a period of 170 cycles which is 193 areons which is 363 years. This term is recovered from the observations of Kepler during the Mars/Earth opposition of 1604 (perigeon: 14 April, 1604). This cycle will recur every 193 Martian areons or 170 perigeons with an accuracy of 1 dar.

The sum of the product of these cycles is 8685 areons. Every Martian day has an integral number and every Martian year has a unique treble character similar to the Julian Day Count of Joseph Scaliger.

The length of an areon is close to 7 terrestrial seasons in length. Due to the eccentricity of the orbit of Mars, perihelion from a measure of the semi major axis is considerably shorter and more energetic than the aphelion: 315 dars to 354 dars. A division of the seasons into 14 month like periods of 48 or 47 dars is possible and fits well with the length of the Phobon (9 dars) and the length of three synodic passages of Deimos (a Deimon) which occurs about every 16 dars. The 3 seasons near the perihelion have 96 dars each and the 4 seasons near the aphelion have 95 dars or 96 dars.

I have concluded that a Martian calendar will become a means of social control and should reflect the actual physical parameters of the environment. The Earth, the Sun, the weather, the satellites and the mysteries are addressed. A more detailed and comprehensive version of this concept is available at the above address, and will be forwarded to the society for publication in their proceedings.
