Calendar Upcoming Widget

Hey, I have a calendar upcoming widget in my footer, and while it looks nice, the dates all look the same (regardless of if there is an event planned for that date or not). To see the names of any events, you have to mouse over the date with the event. If people don't know on which dates the events are taking place, though, then they have no idea over which dates to hover and will never see any events.

How do I edit the appearance of the widget so that it has some indicator about when the events are?
