Every so often there are a bunch of headlines circulated through the news outlets about how everyone’s star sign has changed and what you thought your sign was is different and wrong. As a reference, and for the next time it comes up –
Your astrology sign has not changed and will never change.
The reason behind these stories claiming everyone’s zodiac sign is different than what astrologers are telling people, and that there’s a 13th sign called Ophiucus that astrologers aren’t telling the population about, is because NASA and other astronomical organizations will occasionally send out news of changes in the location of constellations. The constellations do move. What astronomers don’t ever trouble themselves to clarify when they trash astrology is that the constellations do not figure into astrological zodiac signs.
The zodiac signs share their names with the constellations, but astrologers do know the difference.
Astrology uses a 360 degree circle divided into 12 separate signs of 30 degrees each. The starting point of the circle is based not on the starting point of constellations but the beginning of the March equinox, since the astrological zodiac is based on an Earth view relationship to the Sun. Just as your wall calendar is divided into 12 segments based on our relationship to the Sun. The starting point at the March equinox is known as “the Aries point” which is zero degrees of the astrological sign Aries. This has never changed and will never change and it’s not because astrologers are ignorant of astronomy, but because we use a different system of measurement. The static astrological system of measurement used by astrologers just shares the names of the moving astronomical constellations, that’s all.
A few years back, the very astute traditional astrologer Deborah Houlding did a full writeup for Astrodienst clarifying the confusion – if you are looking for an in-depth explanation I recommend reading this highlighted link. Per Houlding’s article:
“Why is the zodiac divided into twelve equal divisions, rather than any other number of equal or unequal divisions? For the same reason that there are twelve calendar months in a year. The zodiac is a circle which maps out the Sun’s position throughout the year… Hence the zodiac adopts the general template that is used in all calendars: there are four major divisions, defined in the zodiac by four equal quarters separated by 90°, which determine where the ecliptic intersects with the equator to create the astronomical commencement of the four seasons…
The zodiac is a very elegant combination of astronomical and calendrical principles. Although the correlation of zodiac degrees and days in a year is not precise, the use of the zodiac as a reference system that monitors planetary movements and interactions, or considers the impact of seasonal changes, remains perfectly valid. The system has a great depth of philosophical reasoning built into its design, partly because the period in which its development began to aid mathematical astronomy occurred at the time that philosophers, such as Pythagoras, were exploring the mystical nature of shapes and geometrical relationships, and generating metaphysical theories on why numerical arrangements could determine qualities as well as quantities…”
End of story!
