During the year, the Sun passes through each of the constellations of the Zodiac. For example, in August, the Sun is in Leo, and then in September, the Sun is in Virgo.
Here’s your constellation Dates of sun’s entry into astrological signs versus astronomical constellations are the same in 2021 as in 2016. Chart and more explanation at Guy’s Ottewell’s blog.

thirteen constellationsAs the Earth orbits the Sun, our line of sight towards the Sun passes through the thirteen constellations of the zodiac. The ecliptic is the path that the Sun follows through the constellations each year as the Earth's seasons change, also known as the zodiac.
The path of the ecliptic passes through 13 of the 88 constellations officially recognized by the International Astronomical Union (IAU) since 1929. Just 12 of those constellations make up the western zodiac.
The Earth's orientation in space has changed and those descriptions are antiquated; see precession of the equinox. The table above describes the current path of the Sun around the celestial sphere. Notice that although there are 12 "signs of the zodiac," there are actually 13 constellations on the Sun's path.
Because there are about 365.25 days in a year and 360° in a circle, the Sun appears to move along the ecliptic at a rate of slightly less than 1° per day. Through how many constellations does the Sun move every day? Through how many constellations does the Sun move every year? 13 constellations, called the Zodiac.
88 constellationsOrigin of the Constellations Over half of the 88 constellations the IAU recognizes today are attributed to ancient Greek, which consolidated the earlier works by the ancient Babylonian, Egyptian and Assyrian.
the constellations of the zodiacThese 12 constellations, Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpius, Sagittarius, Capricornus, Aquarius, and Pisces, are known as the constellations of the zodiac, and are probably familiar to you through astrology.
The astrological calendar recognizes only twelve zodiac constellations because that number equals the number of months in a calendar year. Each sign corresponds to about thirty days. However, in the sky, the Sun doesn't appear to spend 30 days in each constellation.
Since then about 2000 years have passed and the signs moved forward among the dates by about one sign. So if one's "official" sign is Libra, chances are that the Sun was in constellation Virgo at the time of his/her birth.
Twelve constellations through which the ecliptic passes form the Zodiac.
And the proper motion of Barnard's Star is (drumroll please): 10.3 arcseconds per year. That's 10,300 milli-arcseconds per year—darned fast considering all but the closest stars move at most by a few up to a few hundred milli-arcseconds per year.
If observed through the year, the constellations shift gradually to the west. This is caused by Earth's orbit around our Sun. In the summer, viewers are looking in a different direction in space at night than they are during the winter.
The sun passes through only 13 constellations every year. The constellation in which the sun moves along the elliptic throughout the year is called as a zodiac constellation. As the sun takes a year to pass through these entire 13 constellations, it cannot cover an entire constellation in one day.

Sun’s entry into zodiac constellations, 2021. Ophiuchus the Serpent Bearer isn’t an astrological sign, but it is one of the constellations of the zodiac. In other words, many people are born when the sun appears in front of this constellation. In 2020, the sun crossed into Ophiuchus on November 29. Image via IanRidpath.com.
The sun resides at a longitude of 0 degrees on the ecliptic at the March equinox. The sun is at 90 degrees ecliptic longitude at the June solstice, 180 degrees ecliptic longitude at the September equinox and 270 degrees ecliptic longitude on the December solstice. Image via Wikipedia.
Image via IanRidpath.com. You might know that the real sun in the real sky does not appear in front of a constellation of the zodiac within the same range of dates you’ll see listed in astrological horoscopes. That’s because astrology and astronomy are different systems.
The 88 Constellations: Since ancient times, astronomers and scholars have been keeping track of “asterisms” (aka. constellations) in the night sky. By definition, these are collections of stars that, when viewed from Earth, appear in the same general area as each other night after night.
Since ancient times, astronomers have organized the stars into various constellations. We have the Big Dipper (Ursa Major), Orion the Hunter, and his “Greater Dog” and “Lesser Dog” ( Canis Major and Canis Minor ). And those are just some of the better-known ones. But have you ever wondered if the Sun belongs to one of these collections of stars?

Once again, our Sun cannot be considered to lie in any one of them because – relative to the Earth-bound observer – it passes through them. Alas, the only way to answer this question is to change our perspective.
By 1922, the International Astronomical Union (IAU) officially divided the celestial sphere into 88 constellations.
First, let us consider the astrological answer to this question. Unless you were born prior to the Scientific Revolution – during which time Nicolaus Copernicus proposed the heliocentric model of the Solar System – you know that the Earth revolves around the Sun.
The simple answer is that – in accordance with both ancient astrological tradition and modern astronomy – the Sun technically has no constellation. But if you were to change locations and travel to a new star system, you would then be able to view the Sun as we do other distant collection of stars.
