The Sun on January 31, year by year

These positions are all calculated for 12:00 UT. The degree changes between years, even when the sign stays the same.

Positions are shown to the arcminute. A birth before or after noon has a different degree. UT and your local calendar date can differ.

Reading Sun in Aquarius

Sun in Aquarius is associated with living by principles and questioning how a group works. You might care about changing an unfair rule even when it benefits you personally. A principle needs reconsidering when it overlooks the people affected by it.

Aquarius is fixed air. Air concerns ideas and social exchange; fixed describes sustaining a position. The combination can be read through a commitment to a principle that extends beyond one immediate relationship.

A principle can make decisions consistent. It can also become difficult to revise when an individual case reveals a problem. The useful question concerns how an idea works for the people affected by it, rather than assuming the person is unconventional.

The same birthday can produce different charts

The Moon and other planets move independently of the Sun. People born on January 31 in different years can have different Moon signs and planetary aspects.

Birth time and location also change the Ascendant and houses. Astriel uses Placidus: the Sun's house follows its position between calculated cusps. Its zodiac sign alone cannot supply a house number.

If the birth time is unknown, choose that option in the calculator. A date crossing a sign boundary can leave the Sun sign unresolved; houses remain unavailable.
