Frequently asked questions

What is Zodiac Quill?

Zodiac Quill is an independent online publication focused on zodiac signs, astrology education, symbolism, and the cultural history of astrology. It is not a prediction service.

Is astrology a science?

No. Astronomy is the science of celestial objects. Astrology is a symbolic and historical tradition of interpretation. This site keeps those categories separate.

Do you publish daily fortune-telling horoscopes?

No. The optional Daily Reflection page offers journal questions and seasonal themes for entertainment and culture, not guaranteed outcomes.

What is a sun sign?

In popular English-language astrology, a sun sign is the tropical zodiac sector the Sun occupied at birth. It is one placement among many in a natal chart.

Why do I need a birth time for a rising sign?

The rising sign is the zodiac degree on the eastern horizon at a place and moment. It changes by roughly one degree every four minutes, so time and location matter in the tradition.

What is the difference between a sign and a constellation?

A tropical sign is a thirty-degree seasonal sector. A constellation is an irregular star pattern. They share names for historical reasons and are not the same boundaries.

Do you display advertising?

No. Pages are written as a pure content publication. There are no ad units on the site at present.

Can two people with “incompatible” signs have a good relationship?

Yes. Compatibility lists are cultural interpretations. They are not a scientifically validated method of predicting relationship outcomes.

Who writes the articles?

Pages are published by Zodiac Quill as an independent publication. This site does not invent a named expert staff or certifications.

How can I request a correction?

Email jinghaoa325@gmail.com with the page URL and the issue. The contact form opens your mail application; it does not silently send from the server.
