The term "blue moon" traditionally refers to the second full moon in a calendar month, which occurs approximately every 2.7 years. However, the notion that a blue moon occurs every 20 years may stem from the misunderstanding of different definitions. The infrequency of blue moons is due to the lunar cycle not perfectly aligning with our calendar months, making it a relatively rare occurrence rather than a fixed interval. Therefore, while blue moons do happen roughly every few years, the concept of a 20-year cycle is not accurate.
