Customize Month View

Hello, I’m doing a website for a sports commission and they have events that last seasons throughout the year, which makes the ‘Month’ calendar view pretty ugly: http://www.treasurecoastsports.net/events/month/

Is there a way to either color code the events or just make the month view text smaller so it’s not so over powering on the calendar?
