Compatibility
Cancer + Cancer.
Two of the same sign: doubled tenderness and doubled moods. Two people who love deeply, retreat instinctively, and feel everything — including each other's weather.
Your two charts, together.
A free Compatibility Index and three close degree contacts. No account needed. Birth details are processed to compute the charts and aren’t saved by this calculator.
The good
Where you click
- Profound emotional attunement — you understand each other's needs without asking.
- Both build a warm, safe, nurturing home; family and care come first for both.
- Deep loyalty — once you've let each other in, you're in for good.
The friction
Where you misfire
- Two moody signs can spiral together with no one staying steady.
- Both withdraw into the shell when hurt, so you can stonewall each other for days.
- Hypersensitivity doubles — small slights get nursed into big wounds.
