The full moon calendar includes the full moon dates in 1921 with exact times and dates when they occurred along with full moon names. In 1921 there were 12 full moons, a seasonal blue moon, and two lunar eclipses.

When was the blue moon in 1921?

In 1921 there was seasonal blue moon on Saturday, May 21 because Spring had an extra full moon. As May was the third full moon in a Spring Season with four, the May 21 full moon was called seasonal blue moon.

There are two definitions of blue moons. The most common, and the one you likely know, is when two full moons occur in the same month. The second full moon is typically called a blue moon.

The second definition of a blue moon relates to having an extra full moon during a season. When a season has four full moons, the third full moon of the season is also called a blue moon or a seasonal blue moon to help distinguish between the other definition.

What are the phases of the moon?

The four primary lunar phases are the new moon, the first quarter, the full moon, and the last quarter.

A new moon is the first lunar phase, which occurs on average about once a month or 29.53 days. The moon itself is not visible, though you may be able to “see” it because it blocks the visibility of the stars behind it.

A full moon occurs when the Earth is directly between the Sun and the Moon, allowing the moon to appear illuminated entirely. It happens about once a month, or 29.53 days on average.

The first quarter moon occurs between the new moon and the full moon, and the last quarter moon occurs after the full moon and before the next new moon.
