Version 6.0 of Date::Pcalc is a complete rewrite based on Date::Calc version 6.0.
It is a 1:1 literal transcription from Date::Calc 6.0 and should therefore behave exactly in the same way.
The functionality is also exactly the same. No more missing functions you were used to having with Date::Calc.
This module is meant as a pure-Perl drop-in replacement for Date::Calc when you don't have access to a compiler on your machine.
You will just have to rename all references to Date::Calc[::Object] and Date::Calendar[::Year|::Profiles] to Date::Pcalc[::Object] and Date::Pcalendar[::Year|::Profiles], respectively (i.e., =~ s/Cal/Pcal/;).
