Chinese Numerology

The calculator starts from a single birth date. From it the page builds a Lo Shu grid, finds your zodiac animal with its element and yin or yang polarity, and sets out a Four Pillars (Ba Zi) chart; choosing male or female adds a kua number with eight compass directions. An optional birth hour completes the fourth pillar, a second birth date gives an animal-pairing result, and separate boxes score any house, phone or plate number. The Chinese year turns at Lichun, the solar start of spring, fixed here at 4 February rather than the lunar new year, so anyone born in late January or early February should check which side they fall on.

Take 14 March 1990, female. The grid receives the digits 1, 4, 3, 1, 9, 9 and 0. Zero has no square, so 1 and 9 appear twice, 3 and 4 once, and 2, 5, 6, 7 and 8 stay empty. Two lines are wholly blank, 2-7-6 and 2-5-8, named the Arrow of Apathy and the Arrow of Detachment. The year is Geng-Wu, a yang Metal Horse. For the kua, 9 plus 0 gives 9; adding 5 makes 14, which reduces to 5, and because 5 has no trigram a woman's result becomes 8: Gen, Earth, West group, with Sheng Qi south-west, Tian Yi north-west, Yan Nian west and Fu Wei north-east. A man born that day would get kua 1. The Day Master is Wu, yang Earth.

Read the grid as a map of emphasis. Filled squares point to qualities you may reach for easily; empty ones suggest areas to develop on purpose. Arrows only mark complete lines, and their names follow a popular modern reading of the square, so treat them as prompts. A doubled digit invites a question: does that strength serve you, or crowd out the rest?

Kua directions belong to feng shui practice for placing a desk, bed or front door, and work well as a tie-breaker. If two layouts suit a room equally, facing your Sheng Qi or Fu Wei direction costs nothing.

The Horse's Metal element sits on the Wu Xing wheel, where Earth feeds Metal and Fire tempers it. Pairing results draw on traditional groupings such as the three harmonies and the clashes, and are best used to talk about temperament. The number score rewards digits whose Mandarin names echo pleasant words, such as 8 (bā, near fā), and marks down 4 (sì, close to sǐ), a custom rooted in language rather than in the digits.

Used this way, the calculator shows how one tradition organises a date and a compass, but it cannot tell you what will happen or which choices to make.
