| Ausführliche Beschreibung | A very simple module that export one function called calendar(). This
function returns a data structure representing the dates in a month. The data
structure returned is an array of array references. The first level array
represents the weeks in the month. The second level array contains the actual
days. By default, each week starts on a Sunday and the value in the array is
the date of that day. Any days at the beginning of the first week or the end
of the last week that are from the previous or next month have the value
undef.
.
If the month or year parameters are omitted then the current month or year are
assumed.
.
A third, optional parameter, start_day, allows you to set the day each week
starts with, with the same values as localtime sets for wday (namely, 0 for
Sunday, 1 for Monday and so on).
