Question

Why can you see the moon during the day?

Answer

Why shouldn't you be able to see the moon during the day? The moon is orbiting around the Earth. It takes the moon about 28 days to go right around the Earth and come back to where it started.

The Earth also turns, inside the orbit of the Moon. And, as we know, Earth does a complete revolution in one day, which is 24 hours. That means that the Moon is above the horizon for 12 hours and goes across the sky every day. 

It might not be visible on some occasions - and this is down to how "bright" the Moon is, which is determined by how much sunlight is reflecting from it, but it is still there.

So, to see a Moon during the daytime is not so unusual!
