In Australia at least, it’s common for office jobs to either be 9 to 5 with a half hour lunch break, or 9 to 5:30 with an hour lunch break. Companies I worked at when I lived there (before I moved to the USA) usually did the latter. An hour break was nice because I worked in the center of Melbourne and could walk around the city, get lunch, go to the bank if I needed to, buy stuff from one of the computer stores nearby, etc and still make it back to work on time.
Most people don’t actually work 9 to 5 though. That was an idiotic song.
