Mine are allowed out at night, but not during the day. Nevertheless I would vote 'depends'.
In my case, one of my cats has white ears and a white nose which I won't expose to sunlight. They are both old and pop out for a constitutional, then are soon home again. They have been taught to stay at the back of the house, not to go onto the road.
There are students around here, so when they have parties, the cats are kept in.
I don't think you can create a hard and fast rule for all cats on this one. It really depends upon where you live and the habits and needs of particular cats.
