Instead of calculating the difference based on the date (month-day-
year) you could calculate it by the difference of the time since
1.1.1970. You would use getTime() on both, then get the difference
between them. Then you can divide this by 86.400.000 (which is the
milliseconds in a day) to get the exact number of days between the two
dates.
