NAME
    Date::Ordinal - Conversion of dates to ordinal numbers and vice
    versa

SYNOPSIS
        use Date::Ordinal;
        
        $ord     = month2ord('January');           # $ord gets 1
        $mon     = ord2month('1');                 # $mon gets 'January'
        $mon     = ord2month(1);                   # $mon gets 'January'
        $mon     = ord2month('01');                # $mon gets 'January'
        $arryref = all_month_ordinations
        $arryref = all_day_ordinations
        $hashref = ordination_month_pair # {'January' => 01, ... }
        @day     = days

DESCRIPTION
    This module is designed to aid in creation of CGI popup_menus
    and also interaction with SQL databases.

CONVERSION ROUTINES
    There are two conversion routines: `ord2month()' and
    `month2ord()'.

    ord2month()
            This function takes a month number [1..12] and returns a
            string which contains the name of the month identified.
            If the number is not a valid number, then `undef' will
            be returned:

                $mon = ord2month('3');

    month2ord()
            This function takes a month name and returns the integer
            corresponding to the month name, if such exists. If the
            argument could not be identified as a month name, then
            `undef' will be returned:

                $ord = month2ord('March');

            The case of the month name is not important. See the
            section the section on "KNOWN BUGS AND LIMITATIONS"
            below.

QUERY ROUTINES
    There is one function (and a reference variant) which can be
    used to obtain a list of all month names:

    `all_month_names()'
                Returns a list of all month names;

    `all_month_names_ref()'
                Returns a reference to a list of all month names;

    `ordination_month_pair()'
                returns a reference to a hash of the ordination of a month name
                and the month name

    `all_month_ordinations()'
                returns a reference  a hash of the ordination of a month name
                and the month name

PRETTY-PRINTING ROUTINES
    `prezero()'
                if the current number is single-diit, prefix it with a '0'

KNOWN BUGS AND LIMITATIONS
    none
