♋︎ Sun at ~18° Cancer · second decan · Mercury

July 10 zodiac sign: Cancer, second decan

If you were born on July 10, your sign is Cancer, the water sign ruled by Moon: the Sun is in Cancer on this date in every year from 1980 to 2030. The Sun sits about 18° into Cancer on this date, in the second decan, where Cancer's core takes on a Mercury flavour. Here's what the date fixes, and what only your birth time can tell you.

Your sign: Cancer

The cardinal water sign that protects what it loves and remembers everything.

A Cancer Sun is built around emotional intelligence. You feel the room before anyone has spoken; you know who's about to cry, who's lying, and who's having a bad week. This is a real gift. It's also exhausting. The world doesn't have an off switch for empathy, and you absorb things you didn't sign up to absorb.

The date fixes the Sun; the hour fixes the rest. A Cancer born July 10 around sunrise has Cancer rising, and a different first impression from one born at dawn. Your rising sign needs the birth time; the twelve Cancer Sun combinations show what each one changes.

In the US (2000–2014), an average of 12,062 babies were born on each July 10, rank 37 of 366 dates; Cancer is number 3 of 12 signs (8.84%). What's the most common zodiac sign?

The Moon on July 10, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on July 10 was most often in Scorpio (6 years) and least often in Leo, Virgo, and Aquarius (3 years each). Unlike the Sun, the Moon sign depends on the birth year. On July 10, 2026, the Moon moves from Taurus into Gemini at 22:42 UTC.

In 21 of those 51 years (41%) the Moon changed sign during July 10 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 July 10 in 2025, and new in 1983, 2002, and 2021.

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 second decan of Cancer

Each sign is divided into three 10° decans, and each decan has a sub-ruler that shades the sign's core. Degrees 10–20 of Cancer belong to Mercury: how you think, learn, communicate, and process information. Read it as Cancer with a Mercury accent — the water 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 Cancers born on July 10 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 July 10?

July 10 is Cancer, the cardinal water sign ruled by Moon. The Sun sits at roughly 18° Cancer on this date, in the second decan.

What decan is July 10?

The second decan of Cancer (10°–20°), sub-ruled by Mercury. Decans divide each sign into three 10° slices; the sub-ruler adds a second flavour to the sign's core — here how you think, learn, communicate, and process information.

In the Golden Dawn system each decan has a minor arcana card: for the second decan of Cancer it is the Three of Cups (friendship, celebration, community). 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 July 10?

It depends on the year, and in 41% of years on the hour too. For example: in 1980, Gemini or Cancer; in 1990, Aquarius; in 2000, Scorpio; in 2010, Gemini or Cancer; in 2020, Pisces. Over 1980–2030 the Moon on July 10 was most often in Scorpio. A birth time and place pin it down.

Does everyone born on July 10 have the same chart?

No. They share the Sun in Cancer, 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 July 10 in different years can have almost nothing else in common in their charts.
