So if a SOL is a day.

Only strange thing is he chooses to name the current month by the sign in which Mars would be seen if viewed from... the sun! Why in heaven's name (no pun intended) would he not&nbsp;name the month from the sign in which the sun would be viewed from Mars? That is what astrologers do on Earth and would make the most sense to me. He is sort of half-re-inventing the wheel here.</p><p>The celestial sphere is divided into 88 constellations, twelve of which are bissected by the plane of the ecliptic. these twelve are the signs of the zodiac. Viewed from any planet or the sun, any other planet, the sun, and a planet's moons&nbsp;move through these twelve signs. To me the most sensible way of naming months on mars would be to use the name of the constellation in which the sun is currently passing. This would give:</p><p><u>Northern Summer</u><br />Pisces (330&deg (The Fish) <br />Aries (0&deg (The Ram) <br />Taurus (30&deg (The Bull) </p><p><u>Northern Fall</u><br />Gemini (60&deg (The Twins) <br />Cancer (90&deg (The Crab) <br />Leo (120&deg (The Lion) </p><p><u>Northern Winter</u><br />Virgo (150&deg (The Virgin) <br />Libra (180&deg (The Scale) <br />Scorpio (210&deg (The Scorpion) </p><p><u>Northern Spring</u><br />Sagittarius (240&deg (The Archer) <br />Capricorn (270&deg (The Sea-goat) <br />Aquarius (300&deg (The Water-bearer)</p><p>Logically, each martian day should be divided into 55 or 56 sols. However, I believe each sol should be divided into Earth hours, minutes and seconds, with the 25th hour&nbsp;having only 25 minutes. Now would it make sense to group sols into groups of seven and call them martian weeks? That may be open to some debate as the origin of the seven-day week is, as Schmack pointed out, religious. In order to keep things universal, it may be interesting to invent a new, say 10-day week for Mars. We could then simply name the days day1 day2 day3 etc like the portuguese amongst others do.</p><p>&nbsp;</p><p>&nbsp;</p> <div class="Discussion_UserSignature"> <p><em>“An error does not become a mistake until you refuse to correct it.” John F.

<p>This is very interesting: maybe the matian year should be divided into 13 or 14 equal martian "months". Ophiucus really is on the ecliptic and probably should be counted as a 13th sign of the zodiac. It probably wasn't because the ancients needed 12 and not 13 signs for mathematical reasons. Cetus just slightly pokes onto the ecliptic during Mars' northern summer but before and after Cetus lies Pisces, which would create a rather strange calendar. Probably Cetus should be included in the Month of Pisces.</p><p>&nbsp;</p><p>&nbsp;</p> <div class="Discussion_UserSignature"> <p><em>“An error does not become a mistake until you refuse to correct it.” John F.

As the other posated,&nbsp;a day on Mars is only slightly longer than an Earth day. Earth time is skewed by the constantly changing lenth of time it takes radio to travel from Earth to Mars. &nbsp;Months, centuries, decades,&nbsp;minutes&nbsp;and weeks are almost meaningless on Mars:&nbsp;My guess is we will use approximately Earth universal&nbsp;time, or metric time based on the Martian day, year or the Earth second.&nbsp;Pico seconds, to giga seconds are&nbsp;likely best.&nbsp; Neil
