Does this mean he's seeing someone, or is there another explanation?

This guy i know IRL messages me everyday, all day and night. If he goes out with friends, he'll mesage when he gets in. No matter what time it is.
But there's always one night he when he doesn't message at all. It's not always the same night though. . Is there another explanation why that could be , apart from seeing someone that night?
