Imagine a world without streetlights, TVs, or other distractions. In such a world, the Moon would be a big part of our lives. Many cultures have stories about the Moon, often imagining it as a person or a character in their tales. For example, the Yolngu people of Australia see the Moon as a man named Ngalindi, who goes through a cycle of dying and coming back to life every month.
The Moon’s cycles have helped many cultures decide how to divide their year. The Lakota, a Native American tribe, use a lunar calendar with 13 months, each having 28 days. There are many tribal nations in the United States, each with its own way of naming months, often based on natural events.
The Islamic calendar, known as the Hijri calendar, is also based on the Moon. It has 12 months, and each month starts with a new moon. This calendar is used to decide when important events like Ramadan happen. The Hijri year is about 355 days long, which is shorter than the solar year of 365 days. Some calendars make adjustments to match the lunar months with the solar year.
The Chinese calendar also uses the Moon to mark months. Most years have 12 months, but sometimes there are 13 months to keep the calendar in line with the solar year and seasons. Chinese New Year begins on the new moon that appears in late January or early February.
The Moon takes about 28 days to orbit the Earth. It also spins on its axis in about the same time, so we always see the same side of the Moon. We see the Moon because sunlight reflects off its surface. The Moon is always half-lit by the Sun, but from Earth, it looks like it’s changing shape. These changes are called the phases of the Moon.
When we see only a tiny part of the Moon’s lit side, it’s called a new moon. As the Moon moves, we see more of it, leading to a waxing crescent moon. When we see half of the lit side, it’s the first quarter moon. When the entire lit half is visible, it’s a full moon. After that, it becomes the third or last quarter moon. The Moon keeps moving through these phases as it orbits Earth.
Sometimes, the Earth, Moon, and Sun line up perfectly. When the Moon blocks the Sun, we see a solar eclipse. When the Earth casts a shadow on the Moon, it’s a lunar eclipse. Partial eclipses happen when the Moon’s orbit is in the same plane as the Earth. These eclipses occur a few times a year but aren’t always visible everywhere.
Different cultures have unique stories about eclipses. The people of the western Torres Strait Islands see eclipses as a ghost taking the Moon’s spirit, which they believe is a sign of war. The Yolngu people of Elcho Island think a solar eclipse is when the Sun Woman and Moon Man embrace.
While these stories don’t explain the science behind eclipses, they show how important the Moon and other celestial bodies are to human life. The Moon’s cycles have guided us through the night, helped us keep track of time, and connected us through storytelling.
Using paper and art supplies, create your own lunar calendar for the month. Draw each phase of the Moon as it appears throughout the month. Label each phase and write a short description of what happens during that phase. This will help you understand how the Moon’s appearance changes over time.
Write a short story or a play about the Moon, inspired by the cultural tales mentioned in the article. You can imagine the Moon as a character, like Ngalindi, and create your own adventure or myth. Share your story with the class to explore how different cultures view the Moon.
Use a flashlight and a ball to simulate the phases of the Moon. The flashlight represents the Sun, and the ball is the Moon. By moving the ball around you, observe how the light changes on its surface. This will help you visualize why we see different phases from Earth.
Research how different cultures use the Moon to create their calendars. Then, design your own lunar calendar for a year, including names for each month based on natural events or personal interests. Present your calendar to the class and explain your choices.
Learn about solar and lunar eclipses by creating a model using a lamp (Sun), a globe (Earth), and a smaller ball (Moon). Demonstrate how eclipses occur when these celestial bodies align. Discuss why eclipses are rare and how they have been interpreted in different cultures.

**[Narrator]** In a world without streetlights, television, or other distractions, the Moon is hard to ignore. It’s easy to see why, in many cultures around the world throughout time, the lunar landscape has been as familiar as any other in the community. Some stories describe the Moon as if it were a person, connected to and connecting cycles of life.
To the Yolngu people of Australia, the Moon is represented as a man named Ngalindi, who is chased by his wives, dying and regrowing every month.
**[Light piano music]** Moon cycles inform many cultures on how to divide their year. For example, the lunar calendar of the Lakota, a Native American tribal nation, consists of 13 months of 28 days each. There are over 575 tribal nations in the United States, each with its own naming systems. However, the names of the months are often closely tied to events in the natural world.
The Hijri calendar, or Islamic calendar, is a lunar calendar where each moon cycle represents a month. It is used to determine when special observances for Muslims, such as Ramadan, occur. With 12 months in a year, the Hijri calendar year is about 355 days, which is shorter than a solar year, the time it takes for the Earth to complete an orbit around the Sun, approximately 365 days. Some calendars adjust for the difference between lunar months and solar years.
In the Chinese calendar, each new moon marks the beginning of a month. Most years have 12 months, but there are occasional leap years with 13 months to align the calendar year with the solar year and the seasons. Thus, Chinese New Year, the first day of the first month, always falls on the new moon that appears in late January or early February.
Tracking the time it takes for the Moon to orbit the Earth is crucial for many cultures and religions, providing the basis for determining a month. But why does the Moon’s appearance change every four weeks, and what do those changes look like?
**[Mysterious music]** The Moon orbits the Earth in a journey that takes about 28 days. It also rotates on its axis roughly every 28 days, slowly enough that the same face always looks down on Earth. We see the Moon because sunlight reflects off its surface. Being a sphere, the Moon is always half lit and half in shadow. You may have noticed that the Moon appears different from one week to the next—sometimes full and bright, other times a sliver of light, or merely a dark shadow. While it seems like the Moon is changing shape, it is actually just changing position as it orbits the Earth. These changes are called the phases of the Moon.
When the Moon is positioned such that we see only a small part of the lit side, this is called the new moon. As the Moon moves, we see more of it, leading to a waxing crescent moon. When we see half of the Moon, this is the first quarter moon. What we are actually seeing is half of the lit side. When the lit half is fully exposed, we have a full moon, followed by the third or last quarter moon. The Moon continuously moves through its phases as it completes its orbit around the Earth.
**[Mysterious music]** When the Earth, Moon, and Sun align, the Moon can block the Sun from our view, resulting in a solar eclipse. Conversely, when the Earth casts a shadow over the Moon, we experience a lunar eclipse. Partial eclipses occur when the Moon’s orbit is in the same plane as the Earth. These partial solar and lunar eclipses typically happen a few times a year, although they are not always visible from every location on Earth.
Some cultures interpret eclipses as omens of future events, both good and bad. The people of the western Torres Strait Islands view eclipses as the ghost taking the spirit of the Moon, seeing it as an omen of war. The Yolngu people of Elcho Island perceive a solar eclipse as an embrace between the Sun Woman and the Moon Man.
These stories may not precisely describe the physics of eclipses, but they highlight the significance of the Moon’s movements and other celestial bodies in human life. Like many natural cycles, the cycles of the Moon play various roles in cultures across time and the globe, from guiding us through the darkness of night to helping us keep track of days, and connecting us through storytelling.
