Neptune
sign calculator
Neptune dissolves — longing, mysticism, confusion. It makes boundaries porous and meanings fleeting: art is born here, compassion happens here, but clarity also gets lost here. Neptune shows where you are open to something larger, and where you must be careful not to fool yourself with fog.
Where is your Neptune? Your date, time and place are all it takes.

The basics
What Neptune means
Dream, longing and fog
Neptune stands for imagination, spirituality, compassion and art — but also for illusion, escape and confusion. It dissolves boundaries: wherever Neptune works, the clear-cut blurs, and longing, inspiration — or self-deception — surface. It’s the place where you feel connected to something larger than yourself.
Why the house matters more than the sign
Neptune moves very slowly — about 14 years per sign. So its sign describes the collective dream of a whole generation, not you personally. What’s genuinely yours is the house Neptune sits in and the aspects it makes: that’s where imagination, art and spirituality — or the spot where you easily lose clarity — show up in your life.
