December 27 Zodiac Sign: Capricorn, and the Exact Degree

December 27 is Capricorn in every year from 1930 to 2035. The exact degree range, the decan and its ruler, the tarot card that shares it, and what a birthday can and cannot tell you.

December 27: the Sun between 5.0 and 6.5 degrees of Capricorn.
The short answerDecember 27 is Capricorn, in every year from 1930 to 2035 without exception. The Sun sits between 5 and 6 degrees of Capricorn on this date, which puts it in the first decan, ruled by Jupiter.

Is December 27 always Capricorn?

Yes. This date is comfortably inside Capricorn and does not go near a boundary. The Sun was in Capricorn on December 27 in every one of the 106 years from 1930 to 2035, which is as close to a guarantee as this subject offers.

That is worth stating plainly because the sign boundaries do move. The Earth's year is 365.2422 days rather than 365, so the moment the Sun crosses into a sign drifts about six hours later each year and snaps back on a leap year. For a date near a boundary that genuinely changes the answer. For December 27 it does not, and you can stop worrying about it.

Where the Sun actually sits on December 27

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 December 27 the Sun falls between 5.0 and 6.5 degrees of Capricorn, the variation coming from the same leap-year drift.

The first decan of Capricorn

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 Capricorn born in the first decan is not quite the same as one born in the others. December 27 falls in the first, ruled by Jupiter.

In practice that means the Capricorn traits run through a Jupiter filter rather than only through Saturn. The same system assigns a tarot card to every decan: this one is Two 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 Capricorn born on December 27 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 December 27 in a given year shares this Sun, so nothing on this page is personal to you.

With that said: Capricorn is Earth and Cardinal, ruled by Saturn, and the traits most often attached to it are responsible, ambitious, dry humored, reserved and durable. Its recognised weak spot is that it carries what is not hers to carry. The first decan adds Jupiter, 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 December 27.

In practice: if you were born late on December 27, your solar return will often land on December 28 in some years. If you were born early in the day, it will sometimes fall on the 26th. 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 December 27

Every point in the zodiac has one directly across from it, and so does every birthday. For December 27 that is June 27, when the Sun sits at roughly the same degree of Cancer, the opposite sign.

The gap between them is 182 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: Capricorn and Cancer want different things and the tradition treats them as two halves of one problem rather than as enemies. Capricorn and Cancer compatibility is covered here.

Questions people ask

What zodiac sign is December 27?

Capricorn, in every year from 1930 to 2035. The Sun sits between 5.0 and 6.5 degrees of Capricorn on this date.

Why do the zodiac dates change from year to year?

Because the Earth takes 365.2422 days to go round the Sun, not 365. The quarter day adds up, so the moment the Sun crosses into a sign drifts about six hours later each year, then jumps back when a leap day is added.

Can I be two signs at once?

No. The Sun is in one sign at any moment, including the moment you were born. Being born near a boundary is real; being half one sign and half another is not.

What decan is December 27?

The first decan of Capricorn, 0 to 10 degrees, ruled by Jupiter. In the tarot the same ten degrees are the Two of Pentacles.
