About ZodiacCompatibility.org

What this site does

ZodiacCompatibility.org compares Sun signs, exact birth charts, Chinese year animals and pillars, Vedic Moon matching and number symbolism.

• A two-sign comparison with three relationship lenses.
• A month-and-day helper for conventional tropical Sun-sign ranges.
• A complete twelve-sign compatibility chart.

Together, these tools connect sign-to-sign relationship profiles with the repeating geometry of the twelve-sign wheel.

Find the comparison you need

Choose synastry and relationship charts for exact planetary contacts, Chinese/BaZi comparisons for calendar pillars, or Vedic matching for named Moon-based tables. The calculator catalog connects each question to its inputs and output.
