What a June 20 birthday means
On June 20 the Sun sits between 27.8° Gemini and 0.1° Cancer in every year from 1950 to 2025, counting every hour of the day in UTC. Its usual noon position is 28.9° Gemini.
That places June 20 in the third decan of Gemini. The modern triplicity system gives this decan to Aquarius, the older Chaldean order gives it to the Sun, and the Golden Dawn tradition pairs it with the Ten of Swords. In some years the Sun moves on into the first decan of Cancer during this date, so both apply.
Gemini is an air sign of the mutable modality, ruled by Mercury. Cancer is a water sign of the cardinal modality, ruled by the Moon.
June 20 is a cusp date. The Sun changed sign during this date in 4 of the 76 years charted, so someone born on June 20 can be Gemini or Cancer; the birth year and time decide it.

Where these figures come from
The Sun's position was charted at 12:00 UTC on every day from 1950 to 2025, and the start and end of each date were placed on the straight line between neighbouring days, which is exact to a small fraction of a degree. The range covers every hour of June 20 in UTC across all 76 years; someone born far from UTC can sit up to about half a degree beyond it. Decans follow two traditional systems: the triplicity system, which gives each third of a sign to the three signs of its element in turn, and the older Chaldean order of faces, which runs through the seven classical planets from Mars at the start of Aries.
