What time is it right now on Mars? There's a NASA app for that.

And you can download it right here, for Mac, Windows, Linux, OS/2, and other open operating systems. About:

Mars24 is a Java application which displays a Mars sunclock, a graphical representation of the planet Mars showing its current sun- and nightsides, along with a numerical readout of the time in 24-hour format. Other displays include a plot showing the relative orbital positions of Mars and Earth and a diagram showing the solar angle and path for a given location on Mars.

Created at NASA's Goddard Institute for Space Studies.

And for iOS, this looks promising. Haven't tried it, and it's not a NASA product, so YMMV.


  1. I am shocked at how close a martian day is to an earth day.

    A Martian day is 24 earth hours and 37 earth minutes.

  2. I really should get a job across the street from my current job, so I could work on Mars stuff, so I’d have an excuse to reprogram my Nixie watch for Mars time.
