This seems like a very honest way to ask. They're just trying to take a day off to have some fun and relax (which is perfectly reasonable). But they're not making up an excuse about being sick, or having a family obligations, they are being clear that it's a low priority bit of fun giving their Boss a chance to say something like "We're going to be swamped today/then, how about Monday when we'll be slow?"
