Fortune Calculator

📖 Step-by-Step Guide

• Step 1 — Enter Your Birth Details: Input your birth year, month, day, and hour using the Gregorian calendar. The birth hour is important — in Chinese astrology, each two-hour period (时辰, shíchén) corresponds to one of the twelve Earthly Branches. If you don't know your exact birth hour, the reading will be less detailed but still meaningful.
• Step 2 — Select Your Gender: Gender affects the direction of the decade fortune cycles (大运). Males and females progress through their luck pillars in opposite directions relative to their month pillar.
• Step 3 — Generate Your Reading: Click "Calculate Fortune" to compute your Four Pillars (四柱): Year Pillar, Month Pillar, Day Pillar, and Hour Pillar. Each pillar consists of one Heavenly Stem (天干) and one Earthly Branch (地支), together representing the cosmic energy of that moment.
• Step 4 — Understand Your Day Master: The Day Master (日主) — the Heavenly Stem of your Day Pillar — is the most important element in your chart. It represents your core self. The reading explains your Day Master's element, personality traits, and how it interacts with the other Five Elements in your chart.
• Step 5 — Explore Fortune Cycles: The annual fortune section shows how the current year's energy interacts with your chart. The decade fortune (大运) section reveals the major life phases — each lasting ten years — and what themes dominate each period.

🏮 Cultural Background

BaZi (八字, Bā Zì — "Eight Characters"), also known as the Four Pillars of Destiny (四柱命理, Sì Zhù Mìng Lǐ), is one of the most important branches of Chinese metaphysics. Developed during the Tang Dynasty (618–907 CE) and refined through the Song and Ming dynasties, it maps a person's destiny based on the exact moment of birth.

The system works by converting a person's birth date and time into four "pillars," each represented by two Chinese characters — a Heavenly Stem (天干, tiān gān) and an Earthly Branch (地支, dì zhī). Together, these eight characters form a cosmic blueprint that reveals personality, strengths, weaknesses, relationships, career aptitude, and life trajectory.

The ten Heavenly Stems (甲乙丙丁戊己庚辛壬癸) and twelve Earthly Branches (子丑寅卯辰巳午未申酉戌亥) cycle through 60 possible combinations (六十甲子), creating a repeating calendar cycle that has been used for timekeeping since the Shang Dynasty (c. 1600–1046 BCE). Each combination carries specific elemental and yin-yang qualities.

Central to BaZi analysis is the concept of the Day Master (日主) — the Heavenly Stem of the day you were born. All other elements in your chart are interpreted in relation to this core element: some support it, some drain it, some control it, and some are controlled by it. The balance (or imbalance) of these interactions shapes your fortune across different life phases. Many people also check their elemental balance and zodiac compatibility alongside their BaZi reading.

While a full BaZi reading by a qualified practitioner considers dozens of factors — hidden stems, clash and combination relationships, seasonal strength, and more — this calculator introduces the fundamental framework to help you explore this ancient system.
