Basic Car Battery Question

How long can the dome light be on in a car before draining the battery?
Due to a halfway closed door, the light stayed on for about 6 hours before I went back outside and saw it.
If a battery were to be drained and you got a jumpstart does that automatically mean that you need to buy a new battery right away?

(By the way I'm not a car person (in case you couldn't tell). So be nice!)

No your battery will still be fine. But you did not do it any favors.

nope, should last ages for just the little light. if it starts drive it around for a bit if you're worried about the battery, the alternator should re-charge it.

Thanks for the replies...you were right, my car started just fine. I learned something new about the alternator recharging the battery. Anyway, thanks again!
