NAME

Calendar::Simple - Perl extension to create simple calendars

SYNOPSIS

  use Calendar::Simple;


  my @curr      = calendar;             # get current month
  my @this_sept = calendar(9);          # get 9th month of current year
  my @sept_2002 = calendar(9, 2002);    # get 9th month of 2002
  my @monday    = calendar(9, 2002, 1); # get 9th month of 2002,
                                        # weeks start on Monday

DESCRIPTION

A very simple module that exports one function called CWcalendar.

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 CWundef.

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).

EXAMPLE

A simple CWcal replacement would therefore look like this: 

  #!/usr/bin/perl -w


  use strict;
  use Calendar::Simple;


  my @months = qw(January February March April May June July August
                  September October November December);


  my $mon = shift || (localtime)[4] + 1;
  my $yr = shift || ((localtime)[5] + 1900);


  my @month = calendar($mon, $yr);


  print "\n$months[$mon -1] $yr\n\n";
  print "Su Mo Tu We Th Fr Sa\n";
  foreach (@month) {
    print map { $_ ? sprintf "%2d ", $_ : '   ' } @$_;
    print "\n";
  }

Date Range

This module will make use of DateTime.pm if it is installed. By using DateTime.pm it can use any date that DateTime can represent. If DateTime is not installed it uses Perl's built-in date handling and therefore can't deal with dates before 1970 and it will also have problems with dates after 2038 on a 32-bit machine.
