The first full Moon of spring, traditionally known as the Worm Moon, appeared in the skies over Northern Ireland this week. While a total lunar eclipse – or “Blood Moon” – wasn’t visible in the UK, some observers reported seeing its distinct orange glow. This celestial event highlights a tradition of naming full moons that stretches back centuries, predating modern calendars.
Why Do Full Moons Have Names?
Before standardized calendars, cultures relied on lunar cycles to track the seasons. Full Moon names were practical markers of the changing year, often reflecting significant natural events. These names weren’t arbitrary; they were tied to agriculture, animal behavior, and even survival.
The Meaning Behind “Worm Moon”
The March full Moon earned its name because it coincides with the time when earthworms emerge from thawing soil. This is a key sign of springtime’s arrival, signaling warmer weather and renewed growth. Following the Worm Moon, April will bring the Pink Moon (named for early spring wildflowers, not its color), and May will feature the Flower Moon.
What is a Blood Moon?
A Blood Moon isn’t about the color of the Worm Moon itself, but refers to the phenomenon that occurs during a total lunar eclipse. When the Earth passes directly between the Sun and Moon, it blocks sunlight, casting the Moon in a deep reddish hue. This week, those in North and South America, East Asia, and Australia were best positioned to witness the effect.
A Full Year of Lunar Names
The tradition of naming full moons extends throughout the year, each with a unique cultural origin. Here’s a breakdown:
- January: Wolf Moon – Named for the increased howling of wolves during winter when food was scarce.
- February: Snow Moon – Reflects the snowy weather common in North America during this month. Also known as Storm Moon or Hunger Moon.
- March: Worm Moon – Earthworms emerge, signaling spring. Also called Crust Moon.
- April: Pink Moon – Named after the pink wild ground phlox flowers that bloom in early spring. Also known as Egg Moon or Fish Moon.
- May: Flower Moon – Celebrates the abundance of flowers blooming in May. Also called Hare Moon, Corn Planting Moon, or Milk Moon.
- June: Strawberry Moon – Algonquin tribes named it for the strawberry harvest season. Also known as Honey Moon, Rose Moon, or Mead Moon.
- July: Buck Moon – Male deer grow their full antlers at this time. Also called Thunder Moon.
- August: Sturgeon Moon – Named for the sturgeon fish caught in North American waters. Also known as Grain Moon or Black Cherries Moon.
- September: Corn Moon – Marks the harvest season, with a particularly bright full Moon aiding late-night work. If closest to the autumnal equinox, it’s called the Harvest Moon.
- October: Hunter’s Moon – Traditionally a time for preparing for winter through hunting.
- November: Beaver Moon
- December: Cold Moon
The naming of full moons provides a fascinating glimpse into how cultures historically connected with the natural world. These traditions weren’t just about marking time; they were about understanding, respecting, and surviving in harmony with the environment.
The continued observance of these names today serves as a reminder of humanity’s long-standing relationship with the lunar cycle.
