I would suggest using DateTime.pm if you want to do this with modules. It is very helpful when it comes to figuring out which month/week of the year a given date falls in.
Otherwise, when I want to avoid using a module and I am dealing with simple things like sorting based on date, I convert the date to the YYYYMMDD format. Now the dates can be sorted numerically very quickly.
