The sun gets a lot of love in astrology, but for once the moon is finally receiving its fair share in the spotlight — and it’s not with regards to your moon sign, either. Every 29.5 days, the moon goes through eight cycles, and that lunar pattern has had a major surge of interest thanks to TikTok’s moon phase trend. Just like the Sun's placement in the sky can help predict your personality traits and even influence current events, the phase the moon is in at any given time — and the cycle you were born under — has a huge influence on your life, mindset, mood, and soulmates.

"The stages correspond with the stages of the planting cycle, beginning with the potential represented by the seed planted in the ground," Leslie Hale, psychic astrologer at Keen.com, tells Refinery29. "Events in our life begin to unfold the same way the seed takes root and begins to grow," she says. "Being born during the various moon phases affects the personality, and the personal focus in life."

Adds Mysticalcraft Arriana, a Keen.com advisor and tarot card reader, "Knowing what the moon phase was when we were born is essential, as it allows us to add knowledge in life." Your fate isn't necessarily predetermined because of where the moon was on your birth chart, but you may be pulled toward certain personality traits and ways of thinking. And knowing about those predispositions can help you take advantage of them — or avoid them.

On TikTok, moon phases have become popular (like over 430 million views popular) for their insights into soulmate compatibility, be it with lovers, friends, or even pets. More specifically, TikTok creators are focused on how those with moon phases on the opposite side of the lunar cycle tend to be compatible. With the help of a CapCut template, users are creating videos that overlay their moon phase with someone else’s to see if they fit together perfectly like complementary lunar puzzle pieces.

For those who want to dig a little deeper, we asked Hale and Arriana to tell us what each moon phase means for life here on Earth and how they impact the personality traits of people born under each phase. To find out what the moon looked like when you (and your potential soulmate) were born, plug your birthday, time, and place into a moon phase calculator.
