A lunar month (a full period of lunar phases) is close to 29.53 days. 360/29.53 = 12.19° per day. This is the synodic period of revolution of the moon; the revolution as observed from earth, and has to do with the moon's position relative to the sun. So this revolution is what most people will observe most readily, and will intuitively understand to be the moon's revolution. The 360° referred to here are related to the moon's synodic journey across the sky and the degrees are a little larger than the absolute degrees of motion relative to the fixed stars. (The moon in fact revolves MORE than an absolute 360° for each lunar cycle of phases.)
A sidereal revolution (absolute revolution of 360° relative to the fixed stars) is close to 27.32 days. 360/27.32 = 13.18° per day.
A closed fist held at arm's length subtends roughly 10° of sky.
Both Earth and the Moon have day-night cycles because they each rotate on their own axis. This rotation causes different parts of the planet or satellite to receive sunlight at different times, creating the cycle of day and night.
A planet's rotation on its axis determines the length of its day.
It's roughly 29.5 times as long.

One spin is what measures the length of one day
Once.

Twice
saturn rotates 1.25 times in a earth day
Once. One rotation of the earth is the equivalent and the root of a "day".
No. It's much slower. The Earth takes a day to spin round. The Moon takes a month.

One complete spin every 23hours 56minutes 4seconds (rounded) (1 and 1/365) spin every 24 hours
once, that is what determines a day
It spins all day (24 hours)
