How long until 1:20 AM?
1:20 AM is 01:20 in 24-hour time — the middle of the night. Once set, the alarm display counts down to the next 1:20 AM in your local time zone, rolling over to tomorrow if it has already passed today.
Going to sleep at 1:20 AM?
If 1:20 AM is when you plan to go to bed, these wake-up times fall at the end of a ~90-minute sleep cycle, allowing about 15 minutes to fall asleep:
6:05 AM 3 cycles · 4 h 30 min of sleep 7:35 AM 4 cycles · 6 h of sleep 9:05 AM 5 cycles · 7 h 30 min of sleep 10:35 AM 6 cycles · 9 h of sleep
For a short daytime rest, a 20-minute power nap avoids deep sleep entirely — try the timer instead.
