Understanding Moon Phases
Let’s start with some interesting facts. It takes the Moon 29.53 days to orbit completely around the Earth in a full lunar cycle. During this time, the Moon will go through each phase. Since the Moon’s orbital journey takes a little less than a full month, when you click on future dates you’ll notice that–depending on the exact number of days in that month–the Full Moon occurs a day or two earlier each month.
It’s the Moon’s journey as it orbits around Earth that creates the predictable dance between light and shadow. And while the changes may seem slow, on any given day the amount of Moon illuminated by the Sun can vary by as much as 10-percent. The illustration above shows the range of illumination for today - May 28, 2023. The illustration is set to your computer’s clock and therefore gives you an accurate reading for your own particular time zone.
The four main Moon phases in order are the New Moon, First Quarter Moon, Full Moon and Last Quarter Moon. These phases occur at very specific times and are measured by both the Moon’s luminosity and how far along the Moon is in its orbit around Earth.
Moon Phases In History
Imagine a Neanderthal peering out of his cave some dark summer night as the Full Moon rises above the horizon. Nothing on Earth was quite like this strange brilliant object arcing through the night sky. What did he think it was? It’s not hard to imagine how the Moon became the source of many religions, myths and legends throughout the ages.
