Why moon is not visible today?

As the Moon and Earth orbit, the Moon is only visible above the horizon roughly 12 hours out of every 24 hours.

As the Moon circles the Earth, the amount of the lit side we see changes. These changes are known as the phases of the Moon and it repeats in a certain way over and over.
