If going by phases of the moon (synodic month), it makes 12.37 laps in a year. Not close to a round number.
If going by position in the sky relative to the stars (sidereal month), it makes 13.37 laps - one more than the former measure, because of Earth’s year cancelling out one month.
There are also other ways to measure it, but none of them get anywhere close to an integer number per year.
A bit late, but the moon does not make “almost exactly 13 laps”. Info from https://en.wikipedia.org/wiki/Lunar_month
