 # 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.
