Our genes and circadian biology determine how much sleep we need. On average, we need 7-9 hours of sleep each night. However, some people need much more or less than that. You can set your bedtime to coincide with your wake-up time if you have to get up early. However, if you want to be fresh and productive during the day, you should ideally be awake by 4 a.m.
