Freeform dates are a disaster in data processing. This problem is a good example.
given this sample:
So dd/mm and mm/dd are both possible.
This date now becomes undecidable:
It is either April 7 or July 4.
So unless there is a way to remove undecidable dates, you cannot reliably process your data. So, this whole problem cannot be decided as stated. Which is why the answers you have gotten are not much help. My specialty is calendrics - and I do not know of a solution. It requires intelligent human intervention to look at other data that is related to the problem dates lines of data and hopefully figure it out.

date::format
Date::Format(3) User Contributed Perl Documentation Date::Format(3)NAME
Date::Format - Date formating subroutines
SYNOPSIS
use Date::Format;
@lt = localtime(time);
print time2str($template, time);
print strftime($template, @lt);
print time2str($template, time, $zone);
print strftime($template, @lt, $zone);
print ctime(time);
print asctime(@lt);
print ctime(time, $zone);
print asctime(@lt, $zone);
DESCRIPTION
This module provides routines to format dates into ASCII strings. They correspond to the C library routines "strftime" and "ctime".
time2str(TEMPLATE, TIME [, ZONE])
"time2str" converts "TIME" into an ASCII string using the conversion specification given in "TEMPLATE". "ZONE" if given specifies the
zone which the output is required to be in, "ZONE" defaults to your current zone.
strftime(TEMPLATE, TIME [, ZONE])
"strftime" is similar to "time2str" with the exception that the time is passed as an array, such as the array returned by "localtime".
ctime(TIME [, ZONE])
"ctime" calls "time2str" with the given arguments using the conversion specification "%a %b %e %T %Y
"
asctime(TIME [, ZONE])
"asctime" calls "time2str" with the given arguments using the conversion specification "%a %b %e %T %Y
"
MULTI-LANGUAGE SUPPORT
Date::Format is capable of formating into several languages, these are English, French, German and Italian. Changing the language is done
via a static method call, for example
Date::Format->language('German');
will change the language in which all subsequent dates are formatted.
This is only a first pass, I am considering changing this to be
$lang = Date::Language->new('German');
$lang->time2str("%a %b %e %T %Y
", time);
I am open to suggestions on this.
CONVERSION SPECIFICATION
Each conversion specification is replaced by appropriate characters as described in the following list. The appropriate
characters are determined by the LC_TIME category of the program's locale.
%% PERCENT
%a day of the week abbr
%A day of the week
%b month abbr
%B month
%c MM/DD/YY HH:MM:SS
%C ctime format: Sat Nov 19 21:05:57 1994
%d numeric day of the month, with leading zeros (eg 01..31)
%e numeric day of the month, without leading zeros (eg 1..31)
%D MM/DD/YY
%h month abbr
%H hour, 24 hour clock, leading 0's)
%I hour, 12 hour clock, leading 0's)
%j day of the year
%k hour
%l hour, 12 hour clock
%L month number, starting with 1
%m month number, starting with 01
%M minute, leading 0's
%n NEWLINE
%o ornate day of month -- "1st", "2nd", "25th", etc.
%p AM or PM
%P am or pm (Yes %p and %P are backwards :)
%q Quarter number, starting with 1
%r time format: 09:05:57 PM
%R time format: 21:05
%s seconds since the Epoch, UCT
%S seconds, leading 0's
%t TAB
%T time format: 21:05:57
%U week number, Sunday as first day of week
%w day of the week, numerically, Sunday == 0
%W week number, Monday as first day of week
%x date format: 11/19/94
%X time format: 21:05:57
%y year (2 digits)
%Y year (4 digits)
%Z timezone in ascii. eg: PST
%z timezone in format -/+0000
%d, %e, %H, %I, %j, %k, %l, %m, %M, %q, %y and %Y can be output in Roman numerals by prefixing the letter with "O", e.g. %OY will output
the year as roman numerals.
