@brainsmoke April 11, 1955 is often used as the Year Zero for Martian calendars, although my watch is using AM2000's suggested epoch https://pubs.giss.nasa.gov/docs/2000/2000_Allison_al05000n.pdf
Ooh fun! Calendar math on a different planet with a different *Equation of Time* and dealing with Earth's *Leap Seconds*. Thanks, NASA, for the worked examples and test cases! https://www.giss.nasa.gov/tools/mars24/help/algorithm.html
