The time between two full Moons doesn't actually equal a full month so nearly every three years there are two full Moons in one calendar month. Over the past few years, the second full Moon has come to be known as a "Blue Moon".
In this page, you will find the dates of the next 8 Blue Moons that will occur during the span of the next 20 years.
We offer you the opportunity to view the blue moon and full moon schedule throughout the next 20 years.
