Zodiac Dates & Why Do They Change

Zodiac dates & why do they change

Babylonian astronomers were the first to document the cycles of the planets. They created the 12 Zodiac signs system and were able to track the Sun’s movement through the constellations.

When we talk about zodiac dates, we refer to the times of the year when the Sun appears to move through a particular constellation, such as Aries, Gemini, etc. The Sun stays in each Zodiac sign for approximately one month, which is similar to the months in our calendars.

While our Gregorian calendar year starts on January 1st, the astrological year begins with the spring equinox around March 21st.

The vernal equinox is a significant event, marking the beginning of spring in the Northern Hemisphere. This season, associated with new life and growth, mirrors the astrological theme of new beginnings. Thus, it is a natural starting point for the zodiac cycle, which begins with Aries. Aries, the first sign of the Zodiac, is a pioneer who leads the way for others to follow.

Zodiac Sign Dates in Order

Below are the general dates that mark the periods when the Sun transits each zodiac sign. These are our Sun signs.

  1. Aries: March 21 – April 19
  2. Taurus: April 20 – May 20
  3. Gemini: May 21 – June 20
  4. Cancer: June 21 – July 22
  5. Leo: July 23 – August 22
  6. Virgo: August 23 – September 22
  7. Libra: September 23 – October 22
  8. Scorpio: October 23 – November 21
  9. Sagittarius: November 22 – December 21
  10. Capricorn: December 22 – January 19
  11. Aquarius: January 20 – February 18
  12. Pisces: February 19 – March 20

Just a friendly reminder that there is so much more to astrology than our Sun sign ☺️

Why Do the Zodiac Dates Change?

The dates for zodiac signs typically change by only a day or two at most. These small shifts are due to the slight variations in the Earth’s orbit and the addition of leap years.

On the Cusp: If you were born on a day when the Sun switches from one sign to another, you are considered to be ‘on the cusp.’ This unique position means you might have a blend of characteristics from both zodiac signs, making your astrological profile even more fascinating.

So, while the shifts are generally small, it’s always a good idea to look up the exact dates if you’re close to the cusp.

You can find the correct dates by using any birth chart calculator (there’s one on Astromango, too) or app, or by checking an astrology ephemeris for the Sun.

Example:

Typical Range for Gemini: May 21 – June 20

Because of the reasons mentioned earlier (like leap years and slight variations in Earth’s orbit), these dates can shift slightly from year to year.

  • In 2023, Gemini starts a day later, May 22, and ends on June 21.
  • In 2024, Gemini starts wishing the regular range on May 21 and ends June 20.

Born on the Cusp: If someone is born on May 20, 2023, they are a Taurus. However, if someone is born on May 20, 2024, they are a Gemini. This illustrates how the dates can shift slightly from year to year. These dates are so close that these two people will probably embody the traits of both zodiac signs.

My passion for astrology began in childhood with my grandpa showing me the stars and constellations. I grew up reading horoscopes and absorbing the knowledge from an astrology book, "The Sun Signs," that we had at home. Time has only deepened my love for astrology, leading me to create AstroMango. Here, I'm excited to share my lifelong passion with you!
