Dear Fairy Queen: (and welcome to this board)

Use your noodle and try a google. Just a couple of hints:

How long is a martian year in earth days? In MARTIAN days? (are earth and martian days the same length?)

Why do we have months in our earth calendar? Does it make sense to have them in a martian calendar?

You only need a few basic pieces of data, which you can pry out of the Net in a million places. Then use your calculator (or spreadsheet) and have some fun, e.g., how old are you in martian years?
