How are we able to wake up 1 or 2 minutes before the alarm? How does our bodies know what time it is?

You actually wake up dozens of times during the night, but usually only for a few seconds or minutes, and fall back asleep quickly enough that you have no memory of actually waking up. What happens here is one of those periods lines up with when your alarm goes off, so rather than fall back asleep you just stay awake, and this time you *do* remember the awake period.
Circadian rhythms also play a role, I know when I’m more consistent about waking up at the same time, I’m more likely to wake up just before my alarm, whereas when my sleep is more chaotic I’m getting woken up by my alarm more often.
