Mars Date (Year and Solar Longitude) to Earth Date
The interface that does it for you
The following interface computes, for a given Mars year and solar logitude Ls,
the corresponding Earth date.
Simply enter values of Mars year (integer value) and solar longitude (in degrees, ranging
from 0 to 360) and click on the
"Convert Martian Date and Solar Longitude to Earth Date"
button to obtain the corresponding Gregorian Earth date (note that the Julian date
corresponding to the supplied Mars year and solar longitude is also given on output
but may not be specified as an input parameter).
See also our Earth Date to Martian Solar Longitude
Converter and the page on
seasons and solar longitude for more information.
About the interface and its outputs
interface won't work.
Martian Years are numbered according to the calendar proposed by
R. Todd Clancy (Clancy et al., Journal of Geophys. Res 105, p 9553, 2000):
Martian Year 1 begins (at a time such that Ls=0) on April 11th, 1955.
The purpose of this interface is to provide Earth dates for quick reference and
with reasonable accuracy;
hence the output Earth dates are only given as (UTC) Year/Month/Day (no hours,..., which would
obviously also depend on the local Earth longitude, time zone, etc.).
