When exactly is it nighttime, and no longer evening?
I know that it changes from morning to afternoon, magically, in the twinkle of an eye, at 12:00 noon. And it does something similar, but from night to morning, at 12:00 midnight.
Why is it called midnight, when right after it’s night, it’s morning? How is that the middle of the night, when one second later, it’s no longer night, but morning?
And just when does it change from being afternoon to evening?
