Your birthday is actually a celebration of a trip made by Earth around the Sun one time. For
each trip around our star we "age" one year... or at least that is how we humans express it.

One year of any Planet is defined as the time taken by Planet to complete one round around
the Sun. One year on earth is equal to 365 days i.e. earth takes 365 days to complete one

     Mars :      15 * 365 / 687  =   7 yrs  666 days
     Jupiter :    15 / 12  =  1 yrs 1095 days
