How long until 12:10 PM?

12:10 PM is 12:10 in 24-hour time (1210 in military notation) — the afternoon. The alarm counts down to the next 12:10 PM in your local time zone, rolling over to tomorrow if it has already passed today.

Going to sleep at 12:10 PM?

If 12:10 PM 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:

4:55 PM 3 cycles · 4 h 30 min of sleep 6:25 PM 4 cycles · 6 h of sleep 7:55 PM 5 cycles · 7 h 30 min of sleep 9:25 PM 6 cycles · 9 h of sleep

For a short daytime rest, a 20-minute power nap avoids deep sleep entirely — try the timer instead.
