in reply to Sorting by date

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.

    Just make sure that YYYY is in 4-digit format and MM or DD in 2-digit format.

    Like in this case: 20040113 (for 2003, Jan. 13) may mean numerically different from 2004113 (this might mean 2004, Jan. 13 or 2004, Nov. 3)

    Had you been using a database like MySQL, that shouldn't have been an issue.
