August 1: the Sun between 8.5 and 10.0 degrees of Leo.
The short answerAugust 1 is Leo, in every year from 1930 to 2035 without exception. The Sun sits between 8 and 10 degrees of Leo on this date, which puts it in the first decan, ruled by Saturn.
Is August 1 always Leo?
Yes. This date is comfortably inside Leo and does not go near a boundary. The Sun was in Leo on August 1 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 August 1 it does not, and you can stop worrying about it.
Where the Sun actually sits on August 1
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 August 1 the Sun falls between 8.5 and 10.0 degrees of Leo, the variation coming from the same leap-year drift.

Five of Wands
The first decan of Leo
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 Leo born in the first decan is not quite the same as one born in the others. August 1 falls in the first, ruled by Saturn.
In practice that means the Leo traits run through a Saturn filter rather than only through the Sun. The same system assigns a tarot card to every decan: this one is Five of Wands, which is a genuinely useful second description of the same ten degrees and one almost nobody connects back to a birthday.
What a Leo born on August 1 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 August 1 in a given year shares this Sun, so nothing on this page is personal to you.
With that said: Leo is Fire and Fixed, ruled by the Sun, and the traits most often attached to it are warm, generous, proud, dramatic and loyal. Its recognised weak spot is that it needs the room to notice. The first decan adds Saturn, 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 August 1.
In practice: if you were born late on August 1, your solar return will often land on August 2 in some years. If you were born early in the day, it will sometimes fall on the last day of the previous month. 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 August 1
Every point in the zodiac has one directly across from it, and so does every birthday. For August 1 that is January 29, when the Sun sits at roughly the same degree of Aquarius, the opposite sign.
The gap between them is 181 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: Leo and Aquarius want different things and the tradition treats them as two halves of one problem rather than as enemies. Leo and Aquarius compatibility is covered here.
Questions people ask
What zodiac sign is August 1?
Leo, in every year from 1930 to 2035. The Sun sits between 8.5 and 10.0 degrees of Leo 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 August 1?
The first decan of Leo, 0 to 10 degrees, ruled by Saturn. In the tarot the same ten degrees are the Five of Wands.
