3C7Exdx - Time::DayOfWeek.pm created by Pip@CPAN.org to 
   simply tell what day of the week a specific date is.

NAME

Time::DayOfWeek - calculate which Day-of-Week a date is

VERSION

This documention refers to version 1.0.3CNH7Fs of 
Time::DayOfWeek, which was released on Tue Dec 23 17:07:15:54 2003.

SYNOPSIS

  use Time::DayOfWeek qw(:dow);
  
  my $year  = 2003;
  my $month =   12;
  my $day   =    7;

  print 'The Day-of-Week of $month/$day/$year is: ', 
    DayOfWeek($year, $month, $day), "\n";
  print 'The 3-letter abbreviation of the Dow is: ', 
    Dow($year, $month, $day), "\n";
  print 'The 0-based index of the DoW is: ', 
    DoW($year, $month, $day), "\n";

DESCRIPTION

This module just calculates the Day-of-Week for any particular
date.  It was inspired by the clean Time::DaysInMonth module
written by David Muir Sharnoff <muir@idiom.com>.

2DO

-     What else does DayOfWeek need?

WHY?

The reason I created DayOfWeek was to support other Time modules
which would like to have a Day-of-Week calculated.

USAGE

DoW(<Year>, <Month>, <Day>)

Time::DayOfWeek's core function 
which does the calculation and returns the weekday index
answer in 0..6.  If no Year is supplied, 2000 C.E. is 
assumed.  If no Month or Day is supplied, they are set 
to 1.  Months are 1-based in 1..12.

DoW() is the only function that is exported from a normal 
'use Time::DayOfWeek;' command.  Other functions can be imported
to local namespaces explicitly or with the following tags:

    :all - every function described here
    :dow - only DoW(), Dow(), and DayOfWeek()
    :nam - only DayNames() and MonthNames()
    :day - everything but MonthNames()

Dow(<Year>, <Month>, <Day>)

same as above but returns 3-letter day abbreviations in 'Sun'..'Sat'.

DayOfWeek(<Year>, <Month>, <Day>)

same as above but returns full day names in 'Sunday'..'Saturday'.

DayNames(<@NewDayNames>)

can override default day names
with the strings in @NewDayNames.  The current list of day 
names is returned so call DayNames() with no parameters
to obtain a list of the default day names.

An example call is:

    DayNames('Domingo', 'Lunes',  'Martes',  'Miercoles',
                           'Jueves', 'Viernes', 'Sabado');

MonthNames(<@NewMonthNames>)

has also been included to 
provide a centralized name set.  Just like DayNames(), 
this function returns the current list of month names
so call MonthNames() with no parameters to obtain a list
of the default month names.

NOTES

I hope you find Time::DayOfWeek useful.  Please feel free to e-mail
me any suggestions or coding tips or notes of appreciation 
("app-ree-see-ay-shun").  Thank you.  TTFN.
