About
Simple, accurate calculators for feng shui and numerology.
Lucky Number Calc was built around one idea: the traditional formulas behind feng shui and numerology are precise and mathematical, but most tools online either get the details wrong or bury the calculator behind ads and clutter. We wanted something faster and more accurate — free tools that show their work.
Every calculator on this site is based on published, traditional formulas — the same ones used by feng shui and numerology practitioners — implemented carefully, including edge cases that many other calculators skip, like the Chinese solar calendar boundary used in the Kua number calculation.
What we offer
Kua Number
Your feng shui lucky and unlucky directions, based on your birth date and gender.
Life Path Number
Your core numerology number, calculated from your full date of birth.
Lucky Mobile Number
Check whether a phone number's numerology is compatible with your Life Path number.
A note on accuracy
Feng shui and numerology are traditional practices, not scientific ones. We calculate results according to the standard, widely-used formulas for each system, but different schools of thought and different practitioners sometimes use slightly different methods. We aim to be transparent about the exact formula we use on every calculator page, so you can see precisely how your result was reached.
