Re: Martian Calender - I have created a martian calender...

Today on Mars:  <<-- Days of the week are out of alignment with those on Earth due to the longer Martian Day. September 2020 next alignment estimate.

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html

Martian Year: 35        Martian Month in 12 month format: 9 <<== The Astronomical month should be changing soon.
Solar Longitude: 262.1   Sol Number: 503  Change is +.6 degrees

Note that Solar Longitude measurement varies as a function of location in orbit.

Minus prefix means Mars is approaching the Sun.  Perihelion occurred at Ls 253 on Sol 485 - Earth Date 2020/08/03
Plus prefix means Mars is moving away from the Sun. Aphelion will occur near 70 degrees Ls (per www.planetary.org)

Distance of Mars from the Sun is given by theskylive.com as:   207,006,893 km Difference is +36702 <<= 1589 km/hour at 8.8 on 8/21

Watching Mars accelerate on it's way to aphelion is like watching molasses dry.

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees.
The next Skip Day will occur in September on Earth. A Skip Day occurs when the longer Mars Sol reaches 24 Earth hours.
For those who may be following this proposed calendar closely, there exists a "feature" I had not anticipated.
Days of the week fall behind Earth due to the longer Sol, but they gain when Friday is omitted at the end of a Quarter

Minus prefix means Mars is approaching the Sun.  Perihelion occurred at Ls 253 on Sol 485 - Earth Date 2020/08/03
Plus prefix means Mars is moving away from the Sun. Aphelion will occur near 70 degrees Ls (per www.planetary.org)

Distance of Mars from the Sun is given by theskylive.com as:   207,830,343 km Difference is +80084 <<= 2860 km/hour at 10.3 on 9/05

Watching Mars accelerate on it's way to aphelion is like watching molasses dry. Paint drying might be a better metaphor. At least paint dries!

Sol 518 is Tuesday in the Proposed calendar for Mars. 

The Next New Year's on Mars will occur when Solar Longitude reaches 360 degrees.
The next Skip Day will occur in September on Earth. A Skip Day occurs when the longer Mars Sol reaches 24 Earth hours.
For those who may be following this proposed calendar closely, there exists a "feature" I had not anticipated.
Days of the week fall behind Earth due to the longer Sol, but they gain when Friday is omitted at the end of a Quarter

Re: Martian Calender - I have created a martian calender...

Today on Mars:  <<-- Days of the week are out of alignment with those on Earth due to the longer Martian Day. September 2020 next alignment estimate.

Per http://www-mars.lmd.jussieu.fr/mars/tim … _time.html

Martian Year: 35  Martian Month in 12 month format: 10 <<== The Astronomical month will increment when longitude reaches 300 degrees

Solar Longitude: 272.2   Sol Number: 519  Change is +.6 degrees <<== A skip day is imminent
Previous SL:      271.6  Previous Sol: 518
