How To Install libdate-calc-perl on Ubuntu 20.04
Introduction
In this tutorial we learn how to install libdate-calc-perl on Ubuntu 20.04.
What is libdate-calc-perl
libdate-calc-perl is:
Date::Calc is a Perl module which provides a variety of date calculations based on the Gregorian calendar (the one used in Western countries today), complying with the ISO/R 2015-1971 and DIN 1355 standards which specify things such as what leap years are, when they occur, how the week numbers are defined, what’s the first day of the week, how many weeks (52 or 53) a given year has, and so on.
Although the Gregorian calendar was only adopted 1582 by most (not all) European countries (some countries continued to use the Julian calendar until as late as the beginning of the 20th century!), this package allows you to extrapolate the Gregorian calendar back until the year 1.
If Date::Calc::XS (libdate-calc-xs-perl) is available, this package will automatically accelerate its operation using the C/XS implementation.
