Quote from the contest!"English (United States) regional and language
option settings, and we will always enter dates using a string value
similar to this: March 3, 2008"

But the solution fails if you enter a string date, like March 3, 2008.

Its likely my solution is wrong especially if today is like the 31st
cause I had to fudge not passing the target day / when I hit the first
before I hit the day of month. But the solution provided fails long
before that and we have no test data so I can not see a successful
solution and where I broke down. I would love to see the test data they
used! I understand they can't give back everyone feedback.

Sorry about my venting. Would anyone care to comment on my failed script?
I could not find the rules, so I have been using just the default
ActivePerl install, and all scripts so far have been doable, even the
read from a database, which I'm not to happy with the documentation that
keeps saying you must use the DATASOURCES ( ODBC) panel to associate
the database with the driver. This is totally bad, I did find the info
I wanted so I could create the DSN in the script thank GOODNESS. OOPS,
get of my soap box.

Sorry about the lack of comments. s variables are the starting date, ie
today that I advance to equal the e variables "entered date".

Suggest you don't parse the dates yourself. See Regexp::Common::time,
Time::Normalize, Date::Parse, etc.

Thanks Eric, but are these default modules? If not they break my first
rule.
All scripts should be build with a default ActivePerl install.
