In germany there are laws regulating the opening hours of businesses such as grocery stores (and separate ones for restaurants). The previous federal law allows for opening between 6 until 20 on monday to saturday. Since 2006 the states can overwrite this law locally and most did. But they are only allowed to open on at max 4 sundays each year. Many allow 0-24 but it's culturally barely used. Out of the shops i lived closed to only one even opened from 7 till 24, which was right next to the biggest student housing. Besides that, there are additional costs for employees after midnight, so it is not very attractive to open for the stores at those times. This is vastly different in industrial production factories where shifts covering the full day are much more common.
