Between Capricorn and Aquarius: the year decides

The dates printed beside each sign are a convention. The Sun crosses from Capricorn into Aquarius at one exact moment, and that moment moves: about six hours later each year, then back a day in leap years. So on January 20 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 first decan, and what it changes

The first decan is Saturn twice over. This is Aquarius at its most independent and most principled: these natives think for themselves, keep their word, and hold to an idea when it is unpopular.

The sign: Capricorn

Capricorn begins at the winter solstice, cardinal earth ruled by Saturn. Its natives climb: slowly, without complaint, with an eye on what will still stand in twenty years. They take duty seriously and themselves soberly, and they improve with age. Behind the reserve there is a dry humour and a loyalty that is shown by deeds.

The third decan, and what it changes

The third decan is Mercury's, through Virgo. Ambition is joined by a precise and practical mind: these natives plan carefully, speak sparingly and well, and succeed by method.
