♌︎ Sun at ~17° Leo · second decan · Jupiter

August 10 zodiac sign: Leo, second decan

If you were born on August 10, your sign is Leo, the fire sign ruled by Sun: the Sun is in Leo on this date in every year from 1980 to 2030. The Sun sits about 17° into Leo on this date, in the second decan, where Leo's core takes on a Jupiter flavour. Here's what the date fixes, and what only your birth time can tell you.

Your sign: Leo

The fixed fire sign that brings warmth and refuses to be small.

A Leo Sun puts the Sun in its own sign — your core identity is amplified, radiant, and visible. You generate energy that other people warm themselves on. The friend whose laugh fills the room, the colleague who turns a project into something people are proud to be part of, the host who makes a dinner party an actual event — that's you, in your element.

The date fixes the Sun; the year and hour fix the rest. A Leo born August 10 with the Moon in Leo runs on a different inner weather from one with the Moon in Leo: see Leo Sun, Leo Moon. Your rising sign needs the birth time; the twelve Leo Sun combinations show what each one changes.

In the US (2000–2014), an average of 11,687 babies were born on each August 10, rank 96 of 366 dates; Leo is number 1 of 12 signs (8.96%). What's the most common zodiac sign?

The Moon on August 10, 1980–2030

Across the 51 years from 1980 to 2030, the Moon at noon UTC on August 10 was most often in Leo (6 years) and least often in Taurus, Libra, Scorpio, and Aquarius (3 years each). Unlike the Sun, the Moon sign depends on the birth year. On August 10, 2026, the Moon stays in Cancer the whole UTC day.

In 23 of those 51 years (45%) the Moon changed sign during August 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 August 10 in 1995 and 2014, and new in 1980, 1991, 2010, and 2029.

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 Leo

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 Leo belong to Jupiter: where you grow, where you find meaning, and where life tends to be generous to you. Read it as Leo with a Jupiter accent — the fire 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 Leos born on August 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 August 10?

August 10 is Leo, the fixed fire sign ruled by Sun. The Sun sits at roughly 17° Leo on this date, in the second decan.

What decan is August 10?

The second decan of Leo (10°–20°), 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 August 10?

In the Golden Dawn system each decan has a minor arcana card: for the second decan of Leo it is the Six of Wands (victory, recognition, confidence). 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 August 10?

It depends on the year, and in 45% of years on the hour too. For example: in 1980, Leo; in 1990, Pisces or Aries; in 2000, Sagittarius or Capricorn; in 2010, Leo or Virgo; in 2020, Aries or Taurus. Over 1980–2030 the Moon on August 10 was most often in Leo. A birth time and place pin it down.

Does everyone born on August 10 have the same chart?

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