We really don't (yet) have a posting that addresses the general problem of number of days between two dates. So I have just finished what should be the last date calculation script that I ever write. The math gave me fits and I'm not sure that I have this right yet. But here it is anyway. Some examples of what it can do...

14212
> datecalc -a 1960 12 31 + 7
1961 1 7
> datecalc -D 1960 12 31
