How do phones (and other devices) show the exact date and time even after being switched on after a while?

My phone was switched off since the past hour and I switched it on right now and I realised how normal it was for It to show me the exact present time and date and I wonder how.

Turning your phone off does not cut the power to everything in your phone. Mostly just the screen and main processor. There’s still a lot going on after you’ve powered it down.
