In the early hours of August 23, 2025, skywatchers will encounter a phenomenon known as a Black Moon. While it won’t be visible to the naked eye, this rare event carries both scientific interest and cultural significance.

The Black Moon will reach its peak at 2:06 a.m. EDT (06:06 GMT), appearing in the constellation Leo, just one degree north of the sun.

What makes a Black Moon special? Unlike a supermoon or eclipse, the Black Moon is not an official astronomical term. Instead, it is a nickname used to describe unusual patterns in the lunar cycle. This particular event falls under the seasonal definition, meaning it is the third new moon in a season that unusually contains four. Normally, each season only produces three new moons. However, since the lunar cycle lasts about 29.5 days, it does not align perfectly with our calendar, occasionally creating an “extra” new moon.
The previous seasonal Black Moon occurred on May 19, 2023. In the current year, summer began with a new moon on June 25, followed by others on July 23, August 3, and September 21. With four in total, the August 23 phase earns the Black Moon label.Why you can’t see it During a new moon, the side illuminated by the sun faces away from Earth. At the same time, the moon rises and sets alongside the sun, rendering it invisible against daylight skies. This is why, unlike a lunar eclipse or full moon, a Black Moon passes unnoticed.

However, the days immediately following bring a reward for skywatchers. On August 24 and 25, a slender crescent will return to the evening sky. About 30–40 minutes after sunset, look toward the west to catch a delicate silver arc marking the moon’s reappearance. How rare are they? Seasonal Black Moons occur only once every 33 months. Another definition of the term refers to the second new moon within a single calendar month, which is even less frequent. That version of the Black Moon won’t be seen again until August 31, 2027. Cultural beliefs Beyond astronomy, the Black Moon holds symbolic value. In Pagan and Wiccan traditions, it is seen as a powerful moment for rituals, with spells believed to be more effective during this phase. For some cultures, it symbolizes renewal and transition, further adding to its mystique. FAQs about the Black Moon
