perl-Date-Calc

This package provides all sorts of date calculations based on the Gregorian calendar (the one used in all western countries today). The package is designed as an efficient (and fast) toolbox, not a bulkya ready-made application. It provides extensive documentation and examples of use, multi-language support and special functions for business needs. Moreover, it optionally provides an object-oriented interface with overloaded operators for greater convenience, and calendar objects which support profiles of legal holidays and observances for calculations which need to take those into account.
