What do you consider as *one* year, month etc., fixed (average) values 
or calender values?

When you get numbers for the years, months etc. remaining, and you 
reduce the number of days every day, what would you do when reaching 
zero days? You decrease months by one, and reset days to *which* amount?

Still before your answer.
