Because "[you'd] rather not get into the details", I went and looked it up on "Flat Earth Wiki":
Day/night cycle on a Flat Earth
Day and night cycles are easily explained on a flat earth. The sun moves in circles around the North Pole. When it is over your head, it's day. When it's not, it's night. The sun acts like a spotlight and shines downward as it moves. The picture below illustrates how the sun moves and also how seasons work on a flat earth. The apparent effect of the sun rising and setting is usually explained as a perspective effect.
An animation of the day/night cycle in FET:

This is just... well, it's bad. "When it is over your head it is day. When it's not, it's night." and "The apparent effect of the sun rising and setting is usually explained as a perspective effect." are horrifyingly inadequate descriptions of... well... of nothing at all. A
PERSPECTIVE EFFECT?! With no more description or information than that we're supposed to what? Accept this
NONSENSE? I am absolutely positive you have nothing better to offer than this, and this is, I am sorry to say, garbage. Even if the sun only shone down like a spot-light as the animation tends to suggest, would you not still see a GIANT BEAM OF LIGHT shining down, far-off in the distance? Couldn't you see this "spotlight" with a telescope? Oh wait... no... that's right... you can't see it due to the "perspective effect." Terrible. Just terrible.
