What Is Friendship Compatibility?
Friendship compatibility between the signs shows how easily two signs understand each other, communicate and support each other as friends. By tradition the fire signs are energetic and spontaneous, the earth signs practical and reliable, the air signs sociable and freedom-loving, and the water signs emotional, intuitive and caring.
Signs of the same element or of compatible elements have an easier friendship. The harder combinations ask for more patience.

Frequently Asked Questions
How do the signs influence friendship?
By tradition the sign describes the temperament and the way of communicating. Signs of one element, for example Aries and Leo, understand each other through likeness, and complementary elements balance each other. The difficult combinations work when the two respect their differences.
Which sign is the best friend for everyone?
There is no such sign. Tradition describes Libra, Sagittarius, Gemini and Aquarius as especially sociable, but they have difficult combinations too. For a lasting friendship the respect and the effort of the two matter more.
Can “incompatible” signs be friends?
Yes. A difficult angle describes possible friction and does not forbid a friendship. Aries and Cancer, for example, are fire and water, but when Aries respects the sensitivity of Cancer, and Cancer the courage of Aries, the two complete each other.
What is the difference between friendship and love compatibility?
Friendship looks at communication, shared interests and mutual support. Love adds attraction, closeness and plans for a life together, so two people may get along more easily as friends than as lovers. Love compatibility is on the page Love Compatibility.
Does the birth date matter, or only the sign?
For compatibility by zodiac signs the sign is enough, and the date of birth gives it. The full picture needs the two birth charts with the date, time and place: that is the reading for two. You can calculate your own chart for free on the page Natal Chart.
