At a 7 AM wake, bedtime is easy. Your 2 PM coffee isn't.
Waking at 7 gives you the most forgiving bedtime on this whole site — 11:15 PM for five cycles — so what wrecks it usually isn't staying up late, it's caffeine. Caffeine has a half-life of about five to six hours, so an afternoon coffee at 2 PM still leaves roughly a quarter of the dose in your system at 11 PM, quietly stretching your real fall-asleep time past what the slider assumes. If you can't hit your bedtime, look at your last cup before you look at your alarm.

Questions about a 7 AM wake-up
What time should I go to bed to wake up at 7 AM?
Go to bed at 9:45 PM for six cycles (9 hours) or 11:15 PM for five cycles (7.5 hours). Five cycles suits most adults. Both times target the end of a 90-minute cycle so you wake in light sleep.
Is 11:15 PM enough sleep before 7 AM?
11:15 PM to 7:00 AM is 7.5 hours of sleep across five full cycles, within the 7-9 hours recommended for most adults — timed so your alarm doesn't interrupt deep sleep.
I go to bed on time but still can't sleep — why?
With a 7 AM wake your bedtime is easy, so the culprit is often caffeine. Its half-life is about five to six hours, so an afternoon coffee can still be active at bedtime. Cut your last cup earlier before changing your alarm.
