Anna,
Nope, robbery is purely to do with stealing. However, robbery is (usually) a felony. So if you break into a place with the intent to rob it, then the robbery can count as the 'felony therein' to make the breaking and entering constitute burglary.
Basically, burglary can only be done with breaking and entering (which requires a building). It doesn't matter which felony they intend - arson, rape, grand theft auto, etc.
And originally, it was at night. That's the rule. But (as far as I know...so far...) courts realized the silliness of that. Some have changed it to get rid of the nighttime requirement, some have created a new 'daytime burglary' definition.
Again, this is just random info I've gleaned from class/law dictionaries. I haven't done major research on it. And I'm a 1L. So I could be wrong. Any upper class students/full lawyers who want to contradict, feel free.
