Last Quarter Moon vs Third Quarter Moon
Have you ever gazed up at the moon and wondered why it looks different every night? One of the most striking differences is between the last quarter moon and the third quarter moon, which are often mistaken for one another. Today, we’ll explore the differences between these two moon phases.
Last Quarter Moon
The last quarter moon appears when the moon is three-quarters of the way through its cycle around the Earth (which takes approximately 29.5 days). This phase is also known as a “half moon” because half of the moon’s surface is illuminated by sunlight while the other half is shrouded in darkness. However, unlike the first quarter moon, the last quarter moon is illuminated on the opposite side, so the illuminated portion appears to be a backward “D” shape.
Third Quarter Moon
The third quarter moon appears one week after the last quarter moon and one week before the new moon. During this phase, the moon appears as a “half moon,” but with the illuminated portion on the opposite side as the last quarter moon. This means the illuminated portion of the moon appears as a “D” shape facing the opposite direction.
The Differences
The last quarter moon and the third quarter moon look very similar, but there are some key differences to look out for. The most notable difference is the direction in which the illuminated portion of the moon faces. As mentioned before, the last quarter moon has a backward “D” shape, while the third quarter moon has a regular “D” shape. Additionally, the last quarter moon appears one week before the third quarter moon during the moon’s cycle.
How to Observe Them
If you want to observe the last quarter moon or the third quarter moon, the best time to do so is in the early morning. These moon phases are often visible before sunrise and are perfect for early-risers or those who stay up late. Look toward the western sky to spot the last quarter moon, or the eastern sky to spot the third quarter moon.

Last Quarter Moon vs Third Quarter Moon
The Moon is something that fascinates a lot of people, regardless of their age, gender or origin. Its changing shapes and phases have always captivated humanity, sparking the imagination and inspiring numerous myths, legends and stories. One of the most interesting phases of the Moon is the last quarter, also known as third quarter, which raises a lot of questions and curiosities. In this blog post, we will answer some of the most frequent questions about these two lunar phases and offer a comprehensive explanation of their differences, similarities, and significance.
What is the difference between last quarter and third quarter?
The terms “last quarter” and “third quarter” both refer to the same phase of the Moon, when it appears half-lit and is situated 90 degrees away from the Sun, as seen from Earth. The only difference between the two terms is their origin and usage. Last quarter is a term used by astronomers, while third quarter is used by navigators and sailors. This is because in the past, sailors and navigators used the Moon’s phases to determine the position of the ship and calculate the longitude, and they needed a precise term to refer to the phase that occurred halfway between Full Moon and New Moon. On the other hand, astronomers use the term last quarter to describe the phase that occurs halfway between Full Moon and New Moon, but also because it is easier to calculate and understand the Moon’s position and illumination from the perspective of its orbit around Earth.
Why is last quarter called the “last quarter”?
The term “last quarter” refers to the fact that after this phase, the Moon will enter its final quarter before the New Moon. This phase is also known as the “waning gibbous” because the illuminated part of the Moon is gradually decreasing until it reaches the crescent shape before the New Moon. It is important to note that the term “waning” refers to the decrease in illumination, not the size of the Moon. The Moon does not change its size or shape during its phases, only its illumination and position relative to the Sun.
What is the significance of last quarter and third quarter?
The last quarter and third quarter have several important significances, both from an astronomical and astrological point of view. Astronomically, these phases mark the halfway point between Full Moon and New Moon, and are useful for calculating the Moon’s position and orbit around Earth. Astrologically, these phases are associated with certain traits, energies and influences that affect different aspects of life, depending on the zodiac sign in which they occur.

Last Quarter Moon vs Third Quarter Moon
Have you ever looked up at the night sky and noticed a crescent moon hanging in the sky, but wondered what exactly that meant? There are several phases of the moon, each with its own unique characteristics, and one of the most commonly confused phases are the Last Quarter Moon and the Third Quarter Moon. In this post, we will explore the differences and similarities between these two phases of the moon and what makes them unique.
What is the Third Quarter Moon?
The Third Quarter Moon is also known as the “last quarter” because it is the last quarter of the lunar cycle before it begins again. During the third quarter phase, the moon appears as a half-moon shape. However, it is inverted from the First Quarter Moon, meaning that the side of the moon that is illuminated faces away from the Earth. This phase of the moon is also known as a waning crescent, and it is the last stage of the waning phase.
What is the Last Quarter Moon?
The Last Quarter Moon is also known as the “third quarter” because it occurs three-quarters of the way through the lunar cycle. During this phase, the moon is also half-illuminated, but it is inverted from the Third Quarter Moon. This means that the side of the moon that is illuminated is facing towards the Earth. This phase of the moon is also known as a waning gibbous, and it is the last phase before the new moon.
What are the similarities between the Third Quarter Moon and the Last Quarter Moon?
The Third and Last Quarter Moons are similar in that they both occur during the waning phase of the moon. In addition, they both appear as half-illuminated moons. They also occur at the same point in the lunar cycle, with the Third Quarter Moon occurring three-quarters of the way through the cycle, and the Last Quarter Moon occurring at the end of the cycle.
What are the differences between the Third Quarter Moon and the Last Quarter Moon?
There are several differences between the Third Quarter Moon and the Last Quarter Moon. One of the main differences is the orientation of the illuminated side of the moon. During the Third Quarter Moon, the illuminated side of the moon faces away from the Earth, while during the Last Quarter Moon, the illuminated side faces towards the Earth. Another difference is the shape of the moon during each phase. During the Third Quarter Moon, the moon appears as a waning crescent, while during the Last Quarter Moon, it appears as a waning gibbous.
How to observe the Third Quarter Moon and the Last Quarter Moon?
Observing the Third Quarter Moon and Last Quarter Moon is relatively easy with the naked eye, weather permitting. These phases occur about a week apart from each other, with the Third Quarter Moon occurring approximately 21 days after the new moon and the Last Quarter Moon occurring approximately 28 days after the new moon.
To observe the Third Quarter Moon, look towards the western sky just before sunrise. The illuminated side of the moon will be facing away from the Earth, creating a half-moon shape that is essentially a mirror image of the First Quarter Moon.
To observe the Last Quarter Moon, look towards the eastern sky just before sunrise. The illuminated side of the moon will be facing towards the Earth, creating a half-moon shape that is essentially a mirror image of the Third Quarter Moon.
Conclusion
In conclusion, while the Third Quarter Moon and the Last Quarter Moon are similar in some ways, their differences set them apart. Understanding the phases of the moon can be an exciting and enriching experience for sky enthusiasts and casual observers alike, and observing these phases can give us a new appreciation for the mysteries of the universe. Next time you observe a half-illuminated moon high in the sky, take a moment to appreciate the unique and special characteristics of that lunar phase.
