Calendar month/year css

I’m running a slightly modified wp-layout.css file as I sort my way through the css. I’ve modified the headings in the menu container, and I’d like to have the calendar’s month/year follow the same style.
I can’t figure out which of the sections of the default wp-layout.css file modify the title of the calendar. I can change the look of the dates but not the title.
Any ideas?
Thanks
Kevin
