Any way to get out of this habit?

Make a conscious effort to start the chapter in the middle of the night, or at dusk, or 4:26 PM. If you start it at an odd time, you'll probably end it at a different time, unless you're measuring minutes and putting exactly twelve hours of action into every chapter or something.

But don't worry about it too much. It's just a rough draft; catch what you can. If you find that some of your chapters are on that time schedule, it's no big deal. It's not a novel-breaker, and you'll have plenty of time to work that out in December.

Characters and demons need sleep. Writers do, too, but that's just too bad.

Yep, try starting at odd times, that should help.

I tend to base my chapters around a scene, or if there are multiple short scenes, I base it around the character I'm trying to show. So Jim-Bob might have three scenes, meet the woman at 5pm, woo the woman by 8pm, make the woman breakfast at 8am. Then the next chapters starts with the woman slipping several of Jim-Bob's top secret thumbdrives into her pocket at 9am and leaving to deliver them to her boss. Then the next chapter is Jim-Bob freaking out looking for his thumbdrives at 11:00am.

But a chapter a day is hardly a bad thing. I can see using it stylistically to do some very cool things.

Try thinking about chapters in a different way - almost like a short story. What's your main character's goal for that chapter? What's the climax of the chapter? End it there - either right in the middle of the climax, or after it, when the mini-climax has been resolved but has given your characters a bigger problem to deal with in the next chapter. :-)

Whats wrong with a chapter a day? Chapters are just arbitrary breaks.

Nothing, unless the chapters are ending with "And then they all went to bed". No suspense! Chapters do have a role to play in pacing.

Maybe, for now, you should just eschew chapter breaks altogether. Later, after you have written a lot more, the points in the story where the chapters should begin and end will become more clear.
