Some clocks have a built in receiver to pick up the signal the atomic clock sends out every 15 minutes. Not sure how else to explain it.
How did it know?!?

This clock doesn't have a receiver for the atomic clock. It's using a built-in calendar to decide when to change the time. (once you set it of course.) If you screw up the settings, it will just move it ahead 1 hour from where it is or move it back when it hits 2 AM on the calendar day it's supposed to change. So if you set it 2 hours ahead right now, it'll move it to 3 hours ahead at 2AM on 03/8/2020.
Some clocks will tell you they rely on an atomic clock signal. We have one of those weather station deals that relies on the atomic clock signal to keep time. A receiver is built in to specifically receive that signal. As long as it can "see" it.
Of course, you can always chalk it up to magic. 🤔

That makes the most sense so far. Ok so I hang it on the wall and set the time. That is in the instructions. Just set it and forget it. How does it know what day it is? Because the first day it changed by an hour. Next day same thing. I finally set it wrong by an hour so it would end up correct. Which it did. So I figured it was stupid and would never figure it when to change on DST. Yet, it did. I am so confused.
