Frequently Asked Questions
Are these tools free?
Yes, all 9 tools on 12Zodiacs are completely free to use. No registration, payment, or app download required. All calculations happen in your browser — we do not collect, store, or transmit any personal information.
How accurate is the zodiac calculator?
Our calculator uses the exact Chinese New Year date for each year from 1900 to 2099, sourced from the Purple Mountain Observatory. Many other calculators use January 1st as the cutoff, producing incorrect results for January and February births.
How does the compatibility calculator work?
Our calculator uses the traditional Three Harmonies (San He) and Six Conflicts (Liu Chong) system, which has been used in Chinese astrology for over 3,000 years. Each of the 78 pairings receives a score based on elemental interactions, trine alignment, and traditional astrological principles.
What is BaZi (Four Pillars)?
BaZi (八字) is an advanced Chinese astrology system that maps your destiny using four pillars derived from your birth year, month, day, and hour. Each pillar contains a Heavenly Stem and an Earthly Branch, creating a detailed personal profile that goes far beyond the simple animal sign.
Can I use these tools on my phone?
Yes, all tools are fully responsive and optimized for mobile devices, tablets, and desktops. The interface adapts automatically to your screen size.
Do you store my birth date?
No. All calculations happen entirely in your browser using JavaScript. We do not collect, store, or transmit any personal information.
