Blue Moons aren’t actually blue, but they are as rare as the saying goes.

Don't think the color of the moon will change. The full moon of July 31 is the second one in this month, that's what a "Blue Moon" is. The first full moon happened on July 2.

This phenomenon happens because sometimes the number of days in a calendar month are greater than the cycle of the moon, which is 29.5 days.

The chances of seeing two full moons in the same month is a rare phenomenon that takes place about every 2.6 years.
