Why don't guys want to hang out during the day?

One guy asked on Wednesday to hang out today and when I asked to come pick me up at noon so we can actually go do something when it's still light out, he was like, it's too early and that he'll come later even tho he isn't doing anything. It's like 6pm and he still hasn't said anything.

Another guy, wanted to hang out on Sunday after talking for hours on Saturday. When I asked when he was coming, he said later and came around 6ish.

What's with guys wanting to hang out so late when you can't even do anything at night since it's so dark? How do I make them actually "hang out" earlier?
