How long until 11:50 AM?

11:50 AM is 11:50 in 24-hour time (1150 in military notation) — the morning. The alarm counts down to the next 11:50 AM in your local time zone, rolling over to tomorrow if it has already passed today.

When to go to bed for a 11:50 AM alarm

Sleep runs in cycles of roughly 90 minutes, and waking at the end of a cycle usually feels easier than being pulled out of deep sleep halfway through one. Allowing about 15 minutes to fall asleep, these bedtimes line up with a 11:50 AM wake-up:

2:35 AM 6 cycles · 9 h of sleep

4:05 AM 5 cycles · 7 h 30 min of sleep

5:35 AM 4 cycles · 6 h of sleep

7:05 AM 3 cycles · 4 h 30 min of sleep

Adults generally need 7–9 hours, so five or six cycles (highlighted) suit most people. Treat these as a starting point — cycle length varies from person to person and through the night.
