* The moon is always there: The moon orbits the Earth constantly, regardless of whether it's day or night.
* Full moons are bright: A full moon reflects a lot of sunlight, making it visible even during the day.
* Light conditions matter: You're more likely to see a full moon during the day when the sky is clear and there's less sunlight, like early in the morning or late in the afternoon.
It's a bit like seeing a star during the day – they're always there, but the sun's brightness makes them hard to spot unless conditions are just right.
