The first accurate Martian calendar, complete with weeks, months, and a starting point of the calendar year, was developed in 1936 by Robert G. Aitken, director emeritus of the Lick Observatory in California. Michael Allison's Martian calendar includes a month named for Darius Gangale. Igor Arih's Martian calendar, Frank N. Bauregger's Martian calendar, William H. Becker's Martian calendar, Geoffrey Briggs and Howard Houben's Martian calendar, Leonard Bromberg's Martian calendar. Edgar Rice Burroughs' description of a Martian calendar in several of his novels were inaccurate and mutually inconsistent. Thomas W. Cronin's Martian calendar, Alan Dechert's Martian calendar, Nachum Dershowitz and Edward M. Reingold's Martian calendar, François Forget's Martian calendar, Robert L. Forward's Martian calendar, M. Vertregt's Martian calendar. The earliest known Martian calendar was described in Percy Greg's 1880 utopian novel, Across the Zodiac. Another early Martian calendar was the joint invention of A. E. Douglass and W. H. Pickering, original members of the staff at Lowell Observatory in Arizona. The Darian system includes a Martian calendar as well as calendars for the Galileans and Titan. Tom Gangale's Martian calendar has been widely imitated. Kim Stanley Robinson's Martian calendar is similar in design. James M. Graham and Kandis Elliot's Martian calendar, Pierre Hallet's Martian calendar, William K. Hartmann's Martian calendar, Robert A. Heinlein's Martian calendar, Leon G. Heron's Martian calendar, Fred Hightower's Martian calendar, Bill Hollon's Martian calendar, Mark Knoke's Martian calendar, Peter Kokh's Martian calendar, Ryan Kramer's Martian calendar, Mike Kretsch's Martian calendar, Manfred Krutein's Martian calendar, Roger E. Kuiper's Martian calendar, Lance Latham's Martian calendar. The first operational Martian clock was designed in 1954 by I. M. Levitt of the Fels Observatory in Philadelphia; it displayed the time and date on Earth, as well as the time on Mars and the date on Mars as defined by a Martian calendar of his own invention. James Lovelock's Martian calendar contains 687 days! The Mars Time Group's Martian calendar, Patrick Moore's Martian calendar, Shawn Moore's Martian calendar, Shaun Moss' Martian calendar, Linda Naughton and Robert O'Meara's Martian calendar, Jelmer Oosthoek's Martian calendar, Terry Phelan's Martian calendar, H. Beam Piper's Martian calendar, Olivier Prud'homme's Martian calendar, Keith Salvas' Martian calendar, John J. G. Savard's Martian calendar, Mickey D. Schmidt's Martian calendar, Hans-Joachim Schneider's Martian calendar, Miguel Angel Serra Martín's Martian calendar, Anton Sherwood's Martian calendar, Anders Ström's Martian calendar, Josef Šurán's Martian calendar, Richard Weidner's Martian calendar, Rachel Ann Welton's Martian calendar, William Woods' Martian calendar. Robert Zubrin's Martian calendar is badly flawed in both concepts and details.

The first accurate Martian calendar, complete with weeks, months, and a starting point of the calendar year, was developed in 1936 by Robert G. Aitken, director emeritus of the Lick Observatory in California. Michael Allison's Martian calendar includes a month named for Darius Gangale. Igor Arih's Martian calendar, Frank N. Bauregger's Martian calendar, William H. Becker's Martian calendar, Geoffrey Briggs and Howard Houben's Martian calendar, Leonard Bromberg's Martian calendar.

Vertregt's Martian calendar. The earliest known Martian calendar was described in Percy Greg's 1880 utopian novel, Across the Zodiac. Another early Martian calendar was the joint invention of A. E. Douglass and W. H. Pickering, original members of the staff at Lowell Observatory in Arizona. The Darian system includes a Martian calendar as well as calendars for the Galileans and Titan. Tom Gangale's Martian calendar has been widely imitated. Kim Stanley Robinson's Martian calendar is similar in design. James M.

Levitt of the Fels Observatory in Philadelphia; it displayed the time and date on Earth, as well as the time on Mars and the date on Mars as defined by a Martian calendar of his own invention.
