However, there are a few things to consider:

* Lunar cycle: The moon's cycle from new moon to full moon is about 29.5 days. This means that the actual number of full moons in a year can vary slightly, with some years having 13 full moons.

* Definition of "full moon": Technically, a full moon is only at its fullest for a brief moment. The period when the moon appears "full" can last for a few days.

So, while we usually see a full moon 12 times a year, there might be years with 13, and we can enjoy the moon's fullness for a few days around the actual full moon date.
