This package provides ten output formats of the
commands \today, \printdate, \printdateTeX, and \daterange
(partly language dependent):
ISO (yyyy-mm-dd), numeric (e.g. dd.\,mm.~yyyy), short
(e.g. dd.\,mm.\,yy), TeX (yyyy/mm/dd), original (e.g. dd. mmm yyyy),
short original (e.g. dd. mmm yy), as well as numerical formats with
Roman numerals for the month.
The commands \printdate and \printdateTeX print any date.
The command \daterange prints a date range and leaves out unnecessary
year or month entries.
