If I was a 10 year old and I had to leave for school by 8:45am, I would start at 7:45pm. I say 7:45pm because I would start dimming the lights in my room 3 hours before bed. Around 9:45pm I would start my bedtime ritual so I can be asleep by 10:45 pm and awake by no later than 7:45am to be able to leave by 8:45am.
