I got my retainers yesterday and I was wondering how long I have to keep wearing during the day.? - how long do you have to keep retainers in for

Can I remove it at home and then, when I get to leave or it is too early to do? Of course I use when I sleep. I spent the whole day at home, not only want to wear it when I'm at school or when I go out.
