calculate diferent between years, month, days

[Dré]

Hi Erwin,

Mostly looks great, sometimes is has a miscalculation of 1 day, but i couldn't figure it out why.

Another thing, what i will try to fix, is when the first date is before 1970.
i changed

Code:

unixend = os.time(enddate)

with

Code:

unixend = os.time()
