The tables
Why the pair is rated this way
Two Roosters share one branch, 酉, so there is no harmony or clash between them: the zodiac simply doubles the same sign. The Rooster is yin metal, so a Rooster pair has twice the metal and nothing to balance it from the other side.
酉 is also one of the four branches the old texts call self-punishing (自刑), with the Dragon, Horse and Pig. Two Roosters are read as a pair that can magnify each other's habits, good and bad.
In five-element terms the pair is all metal.
The Rooster rules the autumn month that starts around Sep 8 and the hours from 5 pm to 7 pm.
Outside its own sign, the Rooster's harmony partner is the Dragon, its trine partners are the Snake and the Ox, and the sign it clashes with is the Rabbit.
Reading
In love, friendship and work
Traditionally the Rooster is observant, hard-working and frank. Two Roosters each bring honesty and order and each look for appreciation.
In love, two people of the same sign tend to recognize each other at once; the strengths tend to double, and so do the blind spots.
As friends or co-workers they tend to move at the same pace and understand each other quickly.

Your pair
Check two birth years
A zodiac year starts in late January or February, not on January 1: Chinese New Year calendars switch at Lunar New Year, and saju switches at Lichun, around February 4. If you were born in January or early February, you may belong to the year before.
Beyond the birth year
On Bias Match the animal that counts most is not the birth year but the day branch, the animal in each person's day pillar. If two people's day branches are both Rooster (酉), the compatibility calculator scores that check as zero, neither plus nor minus, next to five other checks.
The text is fixed sentence templates filled in with the classical relation tables built into the Bias Match engine; no AI model generates or rewrites it. For entertainment only: the zodiac describes old patterns, not what will happen between two people.
