What a February 18 birthday means
On February 18 the Sun sits between 28.2° Aquarius and 0.5° Pisces in every year from 1950 to 2025, counting every hour of the day in UTC. Its usual noon position is 29.4° Aquarius.
That places February 18 in the third decan of Aquarius. The modern triplicity system gives this decan to Libra, the older Chaldean order gives it to the Moon, and the Golden Dawn tradition pairs it with the Seven of Swords. In some years the Sun moves on into the first decan of Pisces during this date, so both apply.
Aquarius is an air sign of the fixed modality, ruled by Uranus. Pisces is a water sign of the mutable modality, ruled by Neptune.
February 18 is a cusp date. The Sun changed sign during this date in 33 of the 76 years charted, so someone born on February 18 can be Aquarius or Pisces; 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 February 18 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.
