New Moon, Black Moons are invisible in the sky. This is because the Moon is between Earth and the Sun in its orbit at this Moon phase. Its unilluminated side faces Earth, and only the far side is illuminated.

This is excellent news for stargazers! During this Moon phase, no Moon lights up the night sky, which is perfect for looking at the stars and planets.

Why Do Black Moons Have Different Dates?

Exact Moon Phase Times

Primary Moon phases are defined by where the Moon is in its orbit around Earth. This is why we show the exact time for the Moon phase in UTC.

For example, a Full Moon is defined as the exact moment the Sun, Earth, and Moon line up, which might happen during the day.

A Black Moon is not an official astronomical term but refers to rare New Moon occurrences in our calendar. Because a New Moon is defined as the exact moment when the Sun, the Moon, and Earth are aligned, Black Moons can happen in different months depending on the time zone.

Are Black Moons Rare?

Monthly Black Moons are the most common and happen about once every 29 months, while seasonal Black Moons happen around every 33 months.

A rare occurrence with either no New Moon or no Full Moon in February is sometimes called a Black Moon. These can only happen about once every 19 years.
