Date of Signs by Day and Month of Birth




The dates of the Zodiac signs result from an ancient definition of the division of the Cosmos into 12 segments according to the laws of nature. Please find out how the signs’ dates were defined and learn more about each one of them.

Astrology divides the circle of the heavens into twelve segments, each of which corresponds to one of the 12 signs of the Zodiac, thus defining the date of the signs.

For Astrology, the sun sign contributes to the characterization of the main traits of the astrological personality of each one of us. Therefore, your sign is determined by the Sun’s position in the sky at the time of your birth.

As you have probably noticed, people who share the same sign are very different from each other. This is not due solely to the birth chart of each person: each of us has his chart that, according to specialists, allows us to evaluate a series of cosmic influences, vital circumstances, behaviors, and blockages (self-imposed or external), which refer to exclusively to that person.

On the other hand, each person configures his personality as he matures and integrates new experiences and learning. We are all unique.

You defined the personality of the 12 signs of the Zodiac from a series of assumptions resulting from the esoteric observation and interpretation of the elements of the natural world: the Primordial Qualities, the Elements, the Modes, the Polarities, the Houses and the movements and characteristics attributed to the planets of our solar system.

The Date of the Signs and the Astral Chart

If you are interested in astrology topics, you will have already come across books, newspapers, or magazines with different indications for the date of the signs.

If you were born on transition date, only your birth chart could reveal the actual astrological influences on your personality. Until then, the date of the signs is considered a reference. For other people, however, there is no question when they are born on days that fall within the dates of each of the segments of the Zodiac cycle.

How do you know the date of the signs?

In the following list, you will find a proposed date of the signs used in various sources on the subject and that we follow here at AstroMundus:

The Possibility of a Thirteenth Sign

The base of astrological knowledge dates back many millennia. At that time, technological limitations prevented a correct observation of the Cosmos, giving rise to a 13 sign.

The constellation Ophiuchus, or Serpentarius, for example, was excluded. It is located between Scorpio and Sagittarius and could have given rise to another sign. If so, all signs from October would have another date.

On the other hand, Ancient Astrology did not consider that constellations have different configurations. It takes 45 days for the Sun to pass through the constellation Virgo, but only seven days to pass through the constellation Scorpio. If these factors are taken into account, the date of the signs would be:

  • Aries - From April 19 to May 13
  • Taurus - From May 14 to June 21
  • Gemini - From June 22 to July 20
  • Cancer - From July 21 to August 10
  • Leo - From August 11 to September 16
  • Virgo - From September 17 to October 30
  • Libra - From October 31 to November 23
  • Scorpio - November 24-29
  • Sagittarius - From December 17 to January 20
  • Capricorn - From January 21 to February 16
  • Aquarius - From February 17 to March 11
  • Pisces - From March 12 to April 18
