Super Blue Moons: Your Questions Answered [1]

[]

Date: 2024-08

A monthly blue moon occurs when we see the full moon twice in a single month. The Moon's cycle is 29.5 days, so just a bit shorter than the average length of a calendar month. Eventually that gap results in a full moon happening at the beginning of a month with enough days still remaining for another full cycle ― so a second full moon in the same month. In other words, a full moon that happens on the 1st or 2nd of a month will probably be followed by a second full moon on the 30th or 31st. This happens every two to three years.
