A Kua number calculator determines a person’s Feng Shui Kua (also called Ming Gua) based on their birth date and gender, producing a number 1–9 that indicates auspicious and inauspicious directions.

How to use this calculator and what it means

Understanding your Kua number lets you align sleeping position, desk orientation and room layout with favorable directions for success, health, relationships and personal growth. This guide explains how to use the calculator above, how the calculation works, and practical tips for applying results in a modern home.

How the calculator works

The calculator asks for your date of birth and gender. It uses the commonly accepted Eight Mansions (Ba Zhai) method:
• Take the last two digits of your solar birth year (for example, for 1978 use 78). If your birthday is before the Chinese solar new year (commonly taken as February 4), the calculation should use the previous year — the calculator offers an option to correct for this.
• Add the two last digits together; reduce to a single digit by repeatedly summing digits.
• For males: subtract that single digit from 10. For females: add 5 to that single digit. If the result is two digits, reduce again to a single digit. If the final result is 5, many schools treat it specially: males commonly use Kua 2 and females use Kua 8. (Different Feng Shui schools vary slightly; sources and common practice are noted below.) 

What you get from the result

The calculator returns:
• Your Kua number (1–9).
• Your group (East or West).
• Four auspicious directions — Sheng Chi (prosperity), Tian Yi (health), Nien Yan (relationships), and Fu Wei (personal growth).
• Four inauspicious directions — Total Loss (Jue Ming), Five Ghosts (Wu Gui), Six Killings (Liu Sha), and Obstacles (Huo Hai).
A responsive Plotly donut chart highlights favored compass wedges so you can quickly see which compass directions are supportive for you. The mapping used for directions follows common Eight-Mansions tables; these are widely used references in modern Feng Shui practice.

Practical examples: apply it at home

1. Desk orientation: Place your desk facing your Sheng Chi or Tian Yi to maximize productivity and wellbeing. If your desk must face a different direction, try to spend breaks facing an auspicious direction (rotate your chair briefly).
2. Bed placement: Position the head of your bed toward your Fu Wei or Nien Yan for steady personal growth or improved relationship energy. Keep the area behind the headboard clear and well supported.
3. Seating and social areas: For family rooms or dining, arrange key seating to favor Nien Yan or Sheng Chi so conversations and connections benefit from supportive qi.
4. Small adjustments: If a full rearrangement is impractical, use smaller moves — rotate a lamp, move a plant, or swap art to favor your auspicious sector. Consciously placing commonly used items (desk, bed, workout equipment) in favorable sectors creates cumulative effects.

Calculator limitations and differences between schools

There are traditional variations: some practitioners use the lunar new year instead of Feb 4, some recommend adding 6 to the base number for females born after 2000, and some treat the number 5 differently. This calculator uses the widely adopted last-two-digits method with a Feb 4 solar-year cutoff and a +5 rule for females for consistent results. If you follow a particular school, cross-check with that tradition or consult a practitioner.

Design and WordPress notes

The calculator is implemented as vanilla HTML/CSS/JavaScript and loads Plotly from the CDN, so it can be pasted into a WordPress Custom HTML block, a shortcode, or a theme area that supports raw HTML. It’s sized max-width:720px (the code uses max-width:720px and width:100%), which fits most WordPress content columns between two sidebars without overflowing. The background is white so it displays clearly inside themes of varying colors.

Quick practical tips

Practical quick tips: If you work from home, face your desk toward Sheng Chi or Tian Yi to boost career momentum and wellbeing. Struggling with sleep? Align the head of your bed toward Fu Wei or Nien Yan and keep that sector uncluttered. For relationships, focus seating, lighting and artwork in your Nien Yan sector. Even small changes — moving a chair, adjusting a lamp, or hanging a mirror thoughtfully — can help you interact more consciously with supportive directions. Try changes gradually and note effects.

FAQ

Q: What if my Kua result is 5?
A: Different schools treat 5 specially. A common modern convention is: males use Kua 2 and females use Kua 8. The calculator will display that note when 5 arises.

Q: Should I use Gregorian or lunar year?
A: This calculator uses the modern solar/Gregorian year with a Feb 4 cutoff (Li Chun). If you follow lunar-calendar tradition, convert your birthdate with a lunar calendar and use that year instead.

Q: Why is there a Feb 4 option?
A: Many Feng Shui practitioners prefer using the solar term Li Chun (around Feb 4) as the year boundary for personal Kua calculations; if your birthday falls before this date, your effective Feng Shui birth year is the previous Gregorian year.

Q: Can I base home renovations solely on Kua?
A: Kua offers useful guidance but a full Feng Shui assessment considers the house Kua, compass facing, topography, and many other factors. Use Kua as one input among others.
