The dates printed beside each sign are a convention. The Sun crosses from Aquarius into Pisces at one exact moment, and that moment moves: about six hours later each year, then back a day in leap years. So on February 18 the answer depends on the year, and in some years on the hour.

The sign: Aquarius
Aquarius is fixed air under Saturn: the idea held firmly. Its natives think for themselves, befriend widely, and keep a certain distance even from those they love. They see how the group could be better arranged and are stubborn about it. Their gift is the clear view from outside; their warmth shows in what they do for others.
The third decan, and what it changes
The third decan is Venus's, through Libra. The distance of the sign softens: these natives are charming, drawn to partnership and to art, and they care about harmony between people as much as about the principle.
The sign: Pisces
Pisces closes the zodiac, mutable water ruled by Jupiter. Its natives take in everything: moods, music, the sorrow of a stranger. They are compassionate, imaginative and hard to pin down, at home in dreams and in prayer. Two fish swim in opposite directions in their sign, and their work is to choose a current without losing their tenderness.
The first decan, and what it changes
The first decan is Jupiter twice over: Pisces at its most trusting. Faith, imagination and generosity are strongest here. These natives believe in what cannot be seen and give without counting.
