Date Calculator is a SuperKaramba theme and a
standalone application for calculating dates. You
can add or subtract days to a date, or calculate
the number of days between two dates. You can
calculate using working days only, and/or
inclusive or exclusive of the start/end date.
There is a configuration dialog for setting
holidays, including variable dates such as "the
1st Monday in June" or "the closest Tuesday to 22
February".
