notepad++ - Keeping strings with wild cards intact while adding CRLF to begining of string -

I want to change the string of each month in a horse racing program. For example, from January 1 to January 31, February 1 to February 28 and so on and insert a CRLF in front of it to create a new line. I need to keep the date intact when I create a new line. This is the part that I can not use on a wild card and retain the original date.
