To know whether you only need 4-6 hours a day of sleep, sleep at the same time as you would on a weekday today without setting an alarm for the next. If you do wake up automatically the next day, then congrats Zhou gong dun like you. If you sleep past your normal waking hours e.g 11am then you are paying off your sleeping debts!
