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

         my @span      = date_span(mon   => 10,  # returns span of dates
                                   year  => 2006,
                                   begin => 15,
                                   end   => 28);

DESCRIPTION

       A very simple module that exports one function called "calendar".

   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).

   date_span
       This function returns a cur-down version of a month data structure which begins and ends
       on dates other than the first and last dates of the month.  Any weeks that fall completely
       outside of the date range are removed from the structure and any days within the remaining
       weeks that fall outside of the date range are set to "undef".

       As there are a number of parameters to this function, they are passed using a named
       parameter interface. The parameters are as follows:

       year
           The required year. Defaults to the current year if omitted.

       mon The required month. Defaults to the current month if omitted.

       begin
           The first day of the required span. Defaults to the first if omitted.

       end The last day of the required span. Defaults to the last day of the month if omitted.

       start_day
           Indicates the day of the week that each week starts with. This takes the same values
           as the optional third parameter to "calendar". The default is 0 (for Sunday).

       This function isn't exported by default, so in order to use it in your program you need to
       use the module like this:

         use Calendar::Simple 'date_span';

   EXAMPLE
       A simple "cal" 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";
         }

       A version of this example, called "pcal", is installed when you install this module.

   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.

   EXPORT
       "calendar"
