Some moons in the outer Solar System have Chaotic Rotation. These bodies don't have a fixed rotation axis or period.
There could still be such a Moon orbiting a planet in the habitable zone, or even a small planet in a belt like structure orbiting close to a red dwarf.
I wonder what lifeforms could evolve when the amount of light/energy received is unpredictable and varies constantly?
Not saying life is impossible on such a moon, but it would be even weirder than just strange day night suggests.
Thousands of years this sounds realistic, but remember the scale of things is in billions of years.
