Moon Rise, Moon Set, and Moon Phase are three different things.

"The moon rises in the east and sets in the west, every day.

It has to. The rising and setting of all celestial objects is due to Earth’s continuous daily spin beneath the sky.

So, when you see a thin crescent moon in the west after sunset, it’s not a rising moon. Instead, it’s a setting moon. In fact, it rose earlier in the morning soon after the sun rose."

So, locally, for me today:

Moon Rise - 1:34 am
Moon Set - 5:20 pm
Meridian Passing - 9:34 am @ 246,883 miles.

It rises and downs same as the sun every day with the rotation of the earth. That has nothing to do with the moon cycle.

Stop being nitpicky and destroy things for others because you have to split hairs.

Reality often takes a backseat to narrative in books/movies/games/etc. If you want to "well akshuly" your way though a book, you're likely to find a lot of details the author got wrong. At the same time, those failed details may provide useful ways for the author to move the story or scene along. "Moonrise" is one of those areas where, if you polled most people, the majority would probably get it wrong. But it's a useful trope in stories where clocks and precise timekeeping aren't a thing and where lunar accuracy is also not important. A character saying "it's well past moonrise" will convey to many readers the idea that it's pretty late in the night. Could it be done another way? Sure, but the trope gets the job done and not one really cares about the inaccuracy.

Is the story set on earth?

If so, is it this earth?

Hey there! I totally get where you're coming from. It’s true, the moon has its own schedule and doesn’t play by the same rules as the sun. It can rise during the day or night, depending on its phase. Authors sometimes simplify things or might not get into the nitty gritty of astronomy. It's kind of like how movies always show people waking up with perfect hair – not exactly realistic, but it gets the point across!

It’s pretty cool how the moon's cycle works, though. It’s always fascinating when you catch a glimpse of it in the daytime, like a secret bonus level in the game of sky-watching.

Maybe one day we'll see more accurate representations in books, and who knows, maybe you'll be the one to educate the next best-selling author! Keep sharing those fun facts!
