Enter the number of seconds per Earth day to see how the days and years' lengths work out! Go fullscreen for the best results! ★★★ Try out some sample lengths! ★★★ • 0.00273790926 for an Earth year, • 0.972972973 for a Mars day, • 1 for an Earth day, • 86164.1 for the seconds in a sidereal Earth day (rarely used for real time), and • 86400 for the seconds in a solar Earth day (mostly used for real time). Because this project uses solar days, the day and year lengths will be estimates in some cases.
