Package: libdate-calc-perl (5.4-5)

Perl library for accessing dates

The package provides a Perl interface to a C library which offers a wide variety of date calculations based on the Gregorian calendar (the one used in all western countries today), complying with the ISO/R 2015-1971 and DIN 1355 standards which specify things 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.
