Calenders on the other planets?

Question

What would a calender year look like from each Planet?
1st one to firgure this out wins best answer.

Just say....for each planet
Merc___months ____days in each month.

Mercury How many months are in it's year and days in it's month

Venus How many months are in it's year and days in it's month

Mars How many months are in it's year and days in it's month

Jupiter How many months are in it's year and days in it's month

Saturn How many months are in it's year and days in it's month

Uranus How many months are in it's year and days in it's month

Neptune How many months are in it's year and days in it's month

Pluto How many months are in it's year and days in it's month

Answer 1

it is not possible to calculate the days in a month or months in a year as it is not mentioned how many days we must consider in month or something like that.

Even on earth you can take 15 days in a month and make totally 24 months in a year

Answer 2

First, to have a month, you need a Moon. The month, on Earth, started off as a way to mark off time with the lunar cycle.
The problem was that the number of months in a year is not a full number. Some calendars use a cycle of 19 years with some years of 12 lunar months and some other years of 13 lunar months. The Gregorian calendar is based on the tropical year (return of seasons); it has kept the "month" as a practical division of the year into 12 parts, but the month is no longer connected with the Moon -- they are purely artificial divisions.

For Mars, there are two choices (Phobos, Deimos) and neither one is good to help determine a martian month (orbital periods are too short).

On Jupiter, they'd be at least four choices (the four Galilean moons) and you could build a calendar using all four. They have the advantage of having resonance orbits (an integer number of orbits of one corresponds to an integer number (different number) of orbits of another).

For Saturn, I'd pick Titan. Neptune = Triton

An interesting part of the exercise would be to find a unit of time for the 'hour'. On Earth we ended up with 24 hours in a day because 12 is a number that can be easily divided by 2, 3, 4, 6. Twelve hours for the day and, later, twelve hours for the night (dividing 12 hours was needed to determine the 'watches': the periods where groups of guards had to keep watch at cities or military camps).

In the case of Mars, you could find a time unit such that the interval from local noon to local noon is a whole number of units AND successive transits of Phobos (or Deimos -- or both) is also a whole number of units.

Answer 3

A day on Venus lasts longer than its year.

There is not just one standard calender for this planet, how could we create a single calender for each of the others?

Months were originally determined by how many full moons there are in a year(13), How can months be determined for planets with no moon or for planets with many moons?

Answer 4

You could have searched and found all the info in less time than it took you to type all that. It's in here;

Answer 5

Every palnet has ıt's own year ( It's orbit and speed) .

Have nice day or days :)
