    What time should I go to bed to wake up at 8:45 AM?

    Sleep runs in cycles of roughly 90 minutes. Waking at the end of a cycle — rather than in the middle of deep sleep — usually feels easier. Assuming it takes about 15 minutes to fall asleep, aim for one of these bedtimes:

    BedtimeSleep you'll get
    11:30 PM6 cycles · 9 h of sleep (recommended)
    1:00 AM5 cycles · 7.5 h of sleep (recommended)
    2:30 AM4 cycles · 6 h of sleep
    4:00 AM3 cycles · 4.5 h of sleep

    Most adults need 7–9 hours. Use the sleep calculator for other wake-up times.
