September 22 Zodiac Sign: Virgo or Libra? Exact Times

Am I Virgo or Libra?

This is the actual question, and almost every page that comes up for it prints an approximate date range and leaves you no better off. Here is the real answer. The Sun does not change sign at midnight, or on the same date every year. The Earth's year is 365.2422 days rather than 365, so the changeover drifts about six hours later each year and jumps back when a leap day is inserted. Over a century that moves it across two or three calendar dates.

On September 22 specifically, the Sun was in Libra rather than Virgo in 9 of the 106 years surveyed: 2004, 2008, 2012, 2016, 2020, 2024, 2028, 2032 and 2033.

Born before that time on that date, you are the earlier sign. Born after it, you are the later one. Those times are US Eastern: if you were born elsewhere, convert. Three hours earlier on the west coast, five hours later in London, and so on.

Where the Sun actually sits on September 22

Not just the sign: the degree. Each sign is thirty degrees wide and the Sun covers roughly one a day, so a birthday pins it to about a degree. On September 22 the Sun falls between 28.7 and 30.0 degrees of Virgo, the variation coming from the same leap-year drift.

The third decan of Virgo

Decans are a much older idea than Sun signs and a more specific one. Each sign divides into three ten-degree stretches, each with its own planetary ruler drawn from the Chaldean order, so a Virgo born in the third decan is not quite the same as one born in the others. September 22 falls in the third, ruled by Mercury.

In practice that means the Virgo traits run through a Mercury filter rather than only through Mercury. The same system assigns a tarot card to every decan: this one is Ten of Pentacles, which is a genuinely useful second description of the same ten degrees and one almost nobody connects back to a birthday.

What a Virgo born on September 22 is like

The honest version first. A birthday gives you the Sun, and the Sun is one of about ten things in a chart. It describes what you are consciously trying to become rather than how you behave on a Tuesday, which is usually the Moon and the rising sign. Everything born on September 22 in a given year shares this Sun, so nothing on this page is personal to you.

With that said: Virgo is Earth and Mutable, ruled by Mercury, and the traits most often attached to it are precise, helpful, observant, self-critical and practical. Its recognised weak spot is that it fixes what nobody asked to have fixed. The third decan adds Mercury, which tends to sharpen that picture rather than soften it.

What your birthday cannot tell you

The three things people most want from astrology, which are their rising sign, their Moon sign and their houses, all need a birth time and a birth place as well as a date. The Moon moves about half a degree an hour, so it can change sign inside a single day. The rising sign changes completely every two hours. A date on its own gets you the Sun and very little else.

If you do not know your birth time, this covers how to get it, including which record to ask your state for and which one leaves the hour off.

Your solar return is not always on your birthday

This surprises people and it follows directly from everything above. A solar return is the moment the Sun comes back to the exact degree it held when you were born, and a year of that cycle is 365.2422 days rather than 365. So the moment drifts about six hours later each year and snaps back on a leap year, which means it regularly falls on the day before or the day after September 22.

In practice: if you were born late on September 22, your solar return will often land on September 23 in some years. If you were born early in the day, it will sometimes fall on the 21st. It is not a mistake in the calculation; it is the same quarter-day that moves the sign boundaries.

That matters if you use the technique, because a solar return chart is cast for that exact moment and for wherever you happen to be standing. How to read one is here.

The date opposite September 22

Every point in the zodiac has one directly across from it, and so does every birthday. For September 22 that is March 20, when the Sun sits at roughly the same degree of Pisces, the opposite sign.

The gap between them is 179 days rather than a tidy half of 365, because the Earth moves faster through its orbit in early January, when it is closest to the Sun, than in early July when it is furthest. The two halves of the year are genuinely different lengths, by about seven days.

Astrologically the opposite date is the other end of your axis: Virgo and Pisces want different things and the tradition treats them as two halves of one problem rather than as enemies. Virgo and Pisces compatibility is covered here.
