January 25 zodiac sign: Aquarius, first decan

If you were born on January 25, your sign is Aquarius, the air sign ruled by Uranus: the Sun is in Aquarius on this date in every year from 1980 to 2030. The Sun sits about 5° into Aquarius on this date, in the first decan, where Aquarius's core takes on a Venus flavour. Here's what the date fixes, and what only your birth time can tell you.

Your sign: Aquarius

The fixed air sign that thinks in systems and refuses to inherit its opinions.

An Aquarius Sun is built around originality and systemic thinking. You don't take "this is how it's done" as a sufficient reason for anything. You ask why, and if the answer is just tradition, you're free to do something different. This makes you a natural innovator, an effective dissident, and an occasional pain in the ass to people who like consensus.

The date fixes the Sun; the year and hour fix the rest. A Aquarius born January 25 with the Moon in Leo runs on a different inner weather from one with the Moon in Aquarius: see Aquarius Sun, Leo Moon. Your rising sign needs the birth time; the twelve Aquarius Sun combinations show what each one changes.

In the US (2000–2014), an average of 11,282 babies were born on each January 25, rank 198 of 366 dates; Aquarius is number 11 of 12 signs (7.93%). What's the most common zodiac sign?

The Moon on January 25, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on January 25 was most often in Libra (6 years) and least often in Cancer, Virgo, and Aquarius (3 years each). Unlike the Sun, the Moon sign depends on the birth year. On January 25, 2026, the Moon moves from Aries into Taurus at 18:05 UTC.

In 20 of those 51 years (39%) the Moon changed sign during January 25 itself, so in those years the birth time decides the Moon as well as the rising sign. Cells with an arrow mark them, with the UTC time of the change. The Moon was exactly full on January 25 in 2005 and 2024, and new in 1982.

Find your birth year. One sign means the Moon spent the whole UTC day there; an arrow means it changed sign that day, at the UTC time shown: born before it, the first sign; after it, the second. The Moon sign calculator settles it in seconds; your birth chart adds the rising sign and houses.

Times in UTC: a birth late in the evening in the Americas, or early in the morning in Asia, can fall on the neighbouring UTC date.

Your decan: the first decan of Aquarius

Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 0–10 of Aquarius belong to Venus: how you love, what you find beautiful, and what you value. Read it as Aquarius with a Venus accent — the air core is unchanged, the emphasis moves.

What the date can't tell you

The Sun is one placement out of ten. Your Moon sign changes every two to three days, so Aquarians born on January 25 in different years have different Moons; your rising sign changes every two hours and needs a birth time and place. Those two carry most of what people mean by "personality" in a chart.

Common questions

What zodiac sign is January 25?

January 25 is Aquarius, the fixed air sign ruled by Uranus. The Sun sits at roughly 5° Aquarius on this date, in the first decan.

What decan is January 25?

The first decan of Aquarius (0°–10°), sub-ruled by Venus. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here how you love, what you find beautiful, and what you value.

What tarot card is January 25?

In the Golden Dawn system each decan has a minor arcana card: for the first decan of Aquarius it is the Five of Swords (conflict, hollow victory, ego). It's a birthday card in the same way a sun sign is — one lens, not a verdict.

What Moon sign is someone born on January 25?

It depends on the year, and in 39% of years on the hour too. For example: in 1980, Taurus; in 1990, Capricorn; in 2000, Virgo or Libra; in 2010, Taurus or Gemini; in 2020, Aquarius. Over 1980–2030 the Moon on January 25 was most often in Libra. A birth time and place pin it down.

Does everyone born on January 25 have the same chart?

No. They share the Sun in Aquarius, but the Moon changes sign every two to three days, the rising sign every two hours, and the outer planets by year. Two people born January 25 in different years can have almost nothing else in common in their charts.
