About Mars New Year

A year on Mars lasts about 687 Earth days (668.6 sols; each sol is 24 h 39 min 35 s), so the Mars New Year does not happen every Earth year. It begins at the northern spring equinox on Mars, when the solar longitude (Ls) reaches 0°. Scientists number Mars years from April 11, 1955 (Mars Year 1). Mars Year 39 begins on September 30, 2026 and Mars Year 40 on August 17, 2028. Dates computed with NASA GISS's Mars24 algorithm.
