Here’s how to see what phase the moon was in on the day you were born

People on TikTok think the moon phase you were born during can indicate something about your personality. 

Earth’s satellite has eight different moon phases: new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, and waning crescent. For centuries, some have believed that the moon emits different energy during its different phases. So much like looking up your astrology sign to learn about oneself, people are looking up their birthdate moon phase. 

How to use your birthdate to find your moon phase

Step 1: Visit

Step 2: Locate the moon phase calculator.  

Step 3: Enter your birthdate. The calculator should generate your moon phase with a brief description of what it means. 

For example, according to, new moon babies, “grow up to be very in tune with what they want, always trying new things and maintaining a childlike wonder.” 

The hashtag #moonphase currently has over 71 million views on TikTok. Some people are comparing their moon phase to their partner’s.

TikToker @alyssabreaultt discovered she is a waxing crescent and her boyfriend is a waning gibbous. Their moons are inversions of each other’s which can be interpreted as the two moon phases completing each other.

The user @lildevildem and her boyfriend’s moon phases also completed each other. She’s a waning crescent and he’s waxing gibbous. Together they create a full moon and a new moon. 

Jillian Mendez said, “the moon thing has to be real because WTF.” She was a full moon and her boyfriend was a new moon — complete opposites.
