February 4: the Sun between 14.7 and 16.2 degrees of Aquarius.
The short answerFebruary 4 is Aquarius, in every year from 1930 to 2035 without exception. The Sun sits between 15 and 16 degrees of Aquarius on this date, which puts it in the second decan, ruled by Mercury.
Is February 4 always Aquarius?
Yes. This date is comfortably inside Aquarius and does not go near a boundary. The Sun was in Aquarius on February 4 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 February 4 it does not, and you can stop worrying about it.
Where the Sun actually sits on February 4
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 February 4 the Sun falls between 14.7 and 16.2 degrees of Aquarius, the variation coming from the same leap-year drift.

The second decan of Aquarius
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 Aquarius born in the second decan is not quite the same as one born in the others. February 4 falls in the second, ruled by Mercury.
In practice that means the Aquarius traits run through a Mercury filter rather than only through Uranus and Saturn. The same system assigns a tarot card to every decan: this one is Six of Swords, which is a genuinely useful second description of the same ten degrees and one almost nobody connects back to a birthday.
What a Aquarius born on February 4 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 February 4 in a given year shares this Sun, so nothing on this page is personal to you.
With that said: Aquarius is Air and Fixed, ruled by Uranus and Saturn, and the traits most often attached to it are independent, inventive, principled, detached and humane. Its recognised weak spot is that it would rather be right than close. The second decan adds Mercury, which tends to sharpen that picture rather than soften it.
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.
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 February 4.
In practice: if you were born late on February 4, your solar return will often land on February 5 in some years. If you were born early in the day, it will sometimes fall on the 3rd. 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 February 4
Every point in the zodiac has one directly across from it, and so does every birthday. For February 4 that is August 7, when the Sun sits at roughly the same degree of Leo, the opposite sign.
The gap between them is 184 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: Aquarius and Leo want different things and the tradition treats them as two halves of one problem rather than as enemies. Aquarius and Leo compatibility is covered here.
Questions people ask
What zodiac sign is February 4?
Aquarius, in every year from 1930 to 2035. The Sun sits between 14.7 and 16.2 degrees of Aquarius 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 February 4?
The second decan of Aquarius, 10 to 20 degrees, ruled by Mercury. In the tarot the same ten degrees are the Six of Swords.
