Mars' Calendar. Time on Mars is easily divided into days based on its rotation rate and years based on its orbit. Sols, or Martian solar days, are only 39 minutes and 35 seconds longer than Earth days, and there are 668 sols (687 Earth days) in a Martian year.

Timekeeping on Mars. (In red) Martian season lengths and time as compared to seasons on Earth (in blue), with marks for the vernal equinox, perihelion, and aphelion. Though no standard exists, numerous calendars and other timekeeping approaches have been proposed for the planet Mars.
22 sie 2012 · In this article we propose a calendar for Mars, building on an analysis by Allison and McEwen 2 of the orbital and rotational elements of Mars. This is not the first attempt at a Martian calendar. Previous proposals have been made by Levitt, 3 Aitken 4, Robinson 5, Zubrin 6, and Gangale 7.
The ejecta of the crater at centre overlies both units, indicating that the crater is younger than both units. The geological history of Mars follows the physical evolution of Mars as substantiated by observations, indirect and direct measurements, and various inference techniques.
17 maj 2023 · A Martian year, also known as a "Martian solar year," is the length of time it takes Mars to complete one orbit around the Sun. Compared to Earth's 365.25 days, a Martian year is much longer, lasting for approximately 687 Earth days. This means that a Martian year is nearly twice as long as an Earth year.
A Martian year is approximately 668.6 sols, equivalent to approximately 687 Earth days [1] or 1.88 Earth years. The sol was adopted in 1976 during the Viking Lander missions and is a measure of time mainly used by NASA when, for example, scheduling the use of a Mars rover .
5 maj 2017 · Over extended Martian winters, the shorter days and reduced sunlight mean that solar-powered spacecraft sometimes have to carefully conserve their energy. Timing of Mars years is also important. Every 26 months, we come closer to Mars, so it's one of the best times to send spacecraft.
