Cutting a large log file in to smaller ones

I have a very large (150 megs) IRC log file from 2000-2001 which I want to cut down to individual daily log files. I have a very basic knowledge of the cat, sed and grep commands. The log file is time stamped and each day in the large log file begins with a "Session Start" string like so:

Session Start: Tue Mar 21 03:54:00 2000

Any idea how I could take this large log file, and use sed/grep to break it up in to individual daily versions? Ideally the output would save in to a directory of my chosing in sequential format. Something like so: "resultingfile001.log" and "resultingfile002.log" and so on. I will manually rename the files afterwards.

Any and all help would be greatly appreciated!
