May 25 zodiac sign: Gemini, first decan

If you were born on May 25, your sign is Gemini, the air sign ruled by Mercury: the Sun is in Gemini on this date in every year from 1980 to 2030. The Sun sits about 4° into Gemini on this date, in the first decan, where Gemini's core takes on a Jupiter flavour. Here's what the date fixes, and what only your birth time can tell you.

Your sign: Gemini

The mutable air sign that lives by language — quick to learn, quick to pivot, quick to bore.

A Gemini Sun makes a mind that genuinely runs faster than most. You learn quickly, talk quickly, and link ideas across domains in a way that surprises specialists. Your gift is the connection — between two unrelated fields, between two people who'd never meet without you, between an old idea and a new use for it. You're a natural translator.

The date fixes the Sun; the hour fixes the rest. A Gemini born May 25 in the late morning has Leo rising, and a different first impression from one born at dawn. Your rising sign needs the birth time; the twelve Gemini Sun combinations show what each one changes.

In the US (2000–2014), an average of 11,098 babies were born on each May 25, rank 267 of 366 dates; Gemini is number 4 of 12 signs (8.56%). What's the most common zodiac sign?

The Moon on May 25, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on May 25 was most often in Scorpio and Aquarius (6 years each) and least often in Capricorn (2 years). Unlike the Sun, the Moon sign depends on the birth year. On May 25, 2026, the Moon moves from Virgo into Libra at 14:34 UTC.

In 21 of those 51 years (41%) the Moon changed sign during May 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 May 25 in 1994 and 2013, and new in 1998 and 2017.

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 Gemini

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 Gemini belong to Jupiter: where you grow, where you find meaning, and where life tends to be generous to you. Read it as Gemini with a Jupiter 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 Geminis born on May 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 May 25?

May 25 is Gemini, the mutable air sign ruled by Mercury. The Sun sits at roughly 4° Gemini on this date, in the first decan.

What decan is May 25?

The first decan of Gemini (0°–10°), sub-ruled by Jupiter. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here where you grow, where you find meaning, and where life tends to be generous to you.

What tarot card is May 25?

In the Golden Dawn system each decan has a minor arcana card: for the first decan of Gemini it is the Eight of Swords (restriction, self-imposed limits, anxiety). 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 May 25?

It depends on the year, and in 41% of years on the hour too. For example: in 1980, Libra; in 1990, Gemini; in 2000, Aquarius; in 2010, Libra or Scorpio; in 2020, Cancer. Over 1980–2030 the Moon on May 25 was most often in Scorpio and Aquarius. A birth time and place pin it down.

Does everyone born on May 25 have the same chart?

No. They share the Sun in Gemini, 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 May 25 in different years can have almost nothing else in common in their charts.
