Personally, I tend to use singular as I more often type the hash with 
the key, so it makes more sense to say "$month{'Aug'}" many times over 
'my %months=()' once.

Personal preference though, of course. I do the same for SQL tables and 
such, with a few notable exceptions (ie: 'users' instead of 'user', 
which usually has an internal value).
