So I checked the moon phases from when we were born and discovered we were both born during waning crescents, just three days apart in the lunar cycle. Has anyone else looked into this and found patterns with their twin flame’s birth moon phase?

The waning crescent thing is pretty significant. People born under this phase are described in lunar astrology as old souls with heightened intuition and psychic abilities (is that sounding familiar?). It’s the final phase before the new moon, so there’s this quality of being between worlds - endings and beginnings. Between the 3D and the 5D.
Really, like any external sign for twin flames, this can only tell you so much. Even the moon phase calculator gives you a vague idea because knowing if someone is your twin flame is hard when you’re working entirely with external signs and confirmations.
What’s interesting, though, about both of you having it is that waning crescent people are said to be completing karmic cycles from previous lifetimes. They’re the wisdom keepers, the ones who can see in the dark when others can’t. The phase spans about 3.5 days, and being born just three days apart means you’re in nearly identical positions in that cycle.
Traditional astrology focuses more on moon signs and aspects rather than phases, but the birth moon phase does reveal how you process emotions and manifest your life purpose. The same phase suggests you both have similar instinctual responses and emotional rhythms. That means a deep understanding, but you also need things at the same time.
Ah… I remember when this was all the rage with people.
I don’t know if anyone ever really had any idea whether matching phases or complementary phases matter more. The TikTok trend started telling people that matching phases = twin flames, complementary phases (that form a full moon together) = soulmates, but I don’t know where that came from, and I don’t believe it is ever that easy.
I don’t think anyone who is really on the twin flame journey is going to tell you that you need complementary phases or matching ones. They can help give you an understanding of some of the energies between you in the 3D, at least.
Lunar nodes are way more significant for karmic connections than birth phases. When one person’s planets touch another’s north or south node, that’s considered a major past-life indicator. Also, look at whether you have any 12th house connections in your charts - that’s the house of karmic bonds and unconscious recognition.
The waning crescent specifically is associated with prophetic abilities and completing unfinished business from previous incarnations. If you’re both born under it, you might both be in similar stages of soul development, working on closure and preparing for new cycles. There’s something about that phase that makes people natural healers and guides for others going through transitions.
Three days apart in the lunar cycle puts you in the same 45-degree phase segment. Your emotional processing styles would be nearly identical, which creates instant understanding but can also create friction if you’re both going through the same mood simultaneously. Different phases might actually balance each other out better in some ways.
Don’t know how I feel about this one. Moon phases at birth weren’t traditionally used for relationship compatibility - that’s a modern development, not ancient astrology, and since twin flames meet in the 3D over multiple lifetimes, you could have different compatibilities according to that each time around.
I would say (like most other external factors), use it for guidance and not confirmation.
Astrologers focus on moon signs, moon house placements, and aspects between charts. The phase thing went viral recently, but it doesn’t have the historical backing that other synastry techniques do. Not saying you shouldn’t consider it… just be cautious with how much you rely on it.
That said, the waning crescent itself carries real spiritual weight across many traditions. It’s the phase of mystics, seers, people who feel like they don’t quite belong in the everyday world. Dane Rudhyar, who developed the modern moon phase personality system in the 1940s, described it as the phase of release and seed preparation. The person embodies the distilled wisdom of the previous cycle.
Being born close together temporally does suggest something beyond coincidence in esoteric teachings. You’re riding the same cosmic wave, dealing with similar karmic themes. Whether that makes someone your twin flame depends more on the actual dynamics of the relationship than any chart marker.
The real question isn’t whether the phases match but whether the connection supports both of your growth. Spiritual indicators can validate what you feel, but they shouldn’t override your actual lived experience. If this person mirrors your deepest patterns and catalyzes transformation, that matters more than any lunar timing.
I just looked up mine and my twin flame’s moon phases and we’re opposite - I was born during a waning gibbous (86% illuminated) and he was born during a waxing crescent (only 14% illuminated). When you add them together, they equal 100%, like a complete full moon between us.
I’m still trying to figure out what this could mean, but it feels symbolic that our phases balance each other out. Like we’re two halves completing the whole lunar cycle together? It’s giving me chills.
When I started my spiritual awakening, I really got into exploring all the astrological connections between us. We’re both waning crescent, too!
His Moon sign is my Sun sign, and my Sun sign is his Moon. Like, the solar system mirrored us. I haven’t calculated the exact percentages of our moon phases yet, but knowing we share that waning crescent energy AND have this Sun/Moon flip is nice. Have you looked into your other placements to see if there are more synchronicities? I’m curious if the three-day difference in your lunar cycle means anything specific.
Interesting! Not all of us have matching moon phases though. I’m a waning gibbous in Capricorn and my TF is a waxing gibbous in Gemini, so literally opposite phases. I don’t know, the differences might matter more than the similarities with this connection. Just don’t want people thinking matching phases are required…
This is the part everyone scrolls past to get back to the moon phase calculator, isn’t it? But it’s absolutely the most important thing said here. We love looking for external validation, and it makes sense, but let’s keep it within the frame of everything else too.
The waning crescent synchronicity is beautiful, and being born three days apart in the lunar cycle is worth noting. But if that connection isn’t actually pushing you both toward growth, healing your deepest wounds, and forcing you to confront everything you’ve been avoiding… then it’s just a neat astrological coincidence between two people.
The Sun/Moon flip you mentioned is one of the more traditional astrological markers people look for. I think birth chart connections overall tend to be more reliable than moon phases alone - there’s a whole thread exploring the various chart patterns people have found with their twins:
Sounds like you’ve got some synchronicities showing up across multiple placements so you might want to take a look.
I went down this rabbit hole too and found out I’m a waxing crescent and my twin is a waning gibbous, which are supposed to balance each other energetically. The moon phase thing can be a cool lens for understanding the push-pull dynamics we experience.
My twin and I share the same moon phase too, we were both born under waxing gibbous moons.
In separation too, I started following lunar ‘phase families’ - the same Sun-Moon angle returns about every 9 years and tends to echo similar themes. I’m also marking our Metonic dates (19 year repeats of our birth phase) and my monthly lunar return. I use those windows for gentle outreach or self-nurture. Keeps me hopeful without chasing.
