Next time someone calls you "two-faced," consider it a lunar compliment worthy of the first quarter moon: Contrary to popular belief, during this phase, only its one side is illuminated, forming a celestial crescent, rather than a half-moon, and marking the waxing period's commencement, as it grows brighter en route to full moon status.

Remember to catch this trendy look in the afternoon or early evening sky! And for all you lunar linguists, keep in mind "half moon" can also refer to third quarter moon styles.

Ah, the first quarter moon: master of masquerades! Disguised as a half-moon, it teases stargazers with its semi-circular splendor! On its cosmic journey, this celestial chameleon rises around high noon and makes its exodus by midnight, reaching peak altitude at sunset: The sneaky truth is, during this phase, we only catch a glimpse of half of the moon's day side, even though it's called a "quarter moon."

6. Tilted Diet
Why did the first quarter moon go on a diet? It felt a little tilted: In the first quarter moon phase, the illuminated half can appear differently tilted around the world due to the angle of the moon's orbit in relation to Earth's axis, making the lunar disk appear top or bottom-heavy depending on your location.
