in reply to Sorting Array of dates in PERL

The DateTime module overloads the string/numeric comparison operators ('<=>' and 'cmp'), so if you can get them into DateTime objects instead of strings, you can use a trivial sort operation (my @sorted_dates = sort { $a <=> $b } @unsorted_dates;.

Otherwise, if you store them in DDMMYYYY format, you can do the same thing (or use 'cmp' if you have slashes in the date). Personally, I prefer to use DateTime since I don't want to be constrained by a specific format.

    don't you mean YYYYMMDD format? I don't think DDMMYYYY would sort properly.

      Ahh, yes, you're right.

      And getting details like this wrong is exactly why you should just use DateTime :)
