Scientific explanation

While the historical meanings of the 'blue moon' are fascinating, let's explore what it actually means from a scientific point of view.

A 'blue moon' does not actually refer to the color of the moon. Instead, it has to do with the timing of full moons in our calendar. Typically, a year has 12 full moons, one for each month. However, sometimes there are 13 full moons in a year, which is where the 'blue moon' comes in.

Here is a simple explanation to help you understand:

• Calendar Strangeness: A 'blue moon' happens approximately every 2.7 years. This is because the lunar cycle (about 29.5 days) does not align perfectly with the months of our calendar.
• Seasonal vs. Monthly: A 'blue moon' can be either the third full moon in a season with four full moons or the second full moon in a single calendar month.
• Not Effectively Blue: Despite its name, the moon does not turn blue. The term 'blue moon' is more about rarity and timing than about the moon's appearance.

Types of blue moons

There are two types of blue moons: the monthly blue moon and the seasonal blue moon. Understanding the difference between these can make your next moon-watching experience even more special.

A monthly blue moon occurs when two full moons occur in the same calendar month. This is quite rare; it usually happens every two or three years. On the other hand, a seasonal blue moon is the third full moon in a season that has four full moons. Usually seasons have three full moons, so having a fourth is unusual and makes the third a blue moon.
