Default iCal icon font?

I was updating my fonts on my computer and somehow messed up the font that is used for my iCal icon (I also use the program iconical to change the iCal's icon to the current date). Do you guys know what font control's that font? It also messed up part of my mac mail display fonts.

Below are screencaps of both issues.
