Seems like a job you need to do only once. If so, and if the entries in the file are ordered by date as your example seems to imply, then why not... just use your favourite text editor?!?

To do it with perl, just read the file sequentially parsing the entries and using a date managing module, like DateTime or Date::Calc to only print out those lines which lie in the wanted range. What have you tried thus far?
