Which element stands for you?
Your Day Master is the stem of your day pillar. Enter a birth date and see it, with your pillars and an element chart, in about a minute.
The date travels in the page address after “#”, which browsers never send to a server.
The five elements · 五行
Generating cycle (相生): Wood feeds Fire → Fire leaves Earth (ash) → Earth bears Metal → Metal carries Water (condensation) → Water feeds Wood. Hover an element to trace it.
The ten Heavenly Stems · 天干
Jia is pictured as a tree growing straight up: steady, principled, inclined to grow in one clear direction.
Yi is pictured as grass, vines and flowering plants: flexible, resourceful, good at finding the gap in a wall.
Bing is pictured as the sun: open, warm, visible to everyone at once.
Ding is pictured as a candle or lamp: focused, steady light in a small space.
Wu is pictured as a mountain or a high wall: stable, protective, slow to move.
Ji is pictured as cultivated soil: receptive, nourishing, quietly productive.
Geng is pictured as raw metal or an axe: direct, decisive, strongest when it has been tempered.
Xin is pictured as jewellery or refined metal: precise, discerning, sensitive to quality.
Ren is pictured as a great river or the ocean: moving, wide-ranging, hard to contain.
Gui is pictured as rain, dew or mist: subtle, perceptive, reaching places a river cannot.
Where the sun is now
The BaZi year begins at Lichun (立春, about 4 February) and moves through 24 solar terms; the 12 darker bars are the terms that start each BaZi month.

How a reading is built
Scroll through the five steps. The chart is a fictional example; its pillars are correctly calculated.
Birth date, birth time (it can stay unknown) and birth place. The place gives the longitude, and the longitude turns clock time into local solar time.
The solar-term boundaries set the year and month pillars; local solar time sets the day and hour. Eight characters in all.
The eight characters are counted and weighed by element and season, to see which elements are plentiful and which are missing.
Every other stem is named by how it relates to your Day Master: what supports it, what it produces, what pressures it.
Ten-year cycles and the coming three years, written as themes for reflection. Never events, never dates to fear.
What you get
Fictional sample · Oct 28, 1988 · 09:40 local solar time
Read right to left in Chinese, left to right here: hour, day, month, year. The day stem 丙 is the Day Master.
A plain count of the eight characters: Earth 4, Fire 2, Water 2, Wood 0, Metal 0. A real reading also weighs hidden stems and the season (autumn earth here).
Peers and rivals: where you share the stage, and where you hold your own.
Output: the Eating God returns, a theme of making, teaching and expression.
Hurting Officer: expression that tests rules. A year to ask which standards are yours.
The year pillars are real; the ten-god names are relative to this fictional Day Master. Themes, not predictions.
“The tension in this chart is not a defect to be healed but an engine: the impulse toward broad visibility, tempered by a steady demand for solid, unglamorous groundwork.”
Fictional example. This chart was made up to show the format; it is not a real customer.
Our rules
A chart describes tendencies. It does not decide who you are or what you deserve.
The cycle map names themes. It never tells you what will happen, or when.
No “bad luck year” warnings, no remedies to buy, no countdowns.
It is not medical, psychological, legal or financial advice. Your decisions stay yours.

Questions
BaZi ("eight characters"), also called the Four Pillars, is a traditional Chinese way of describing a birth moment. It uses the year, month, day and hour, each written as a pair of characters. A reading looks at how the five elements are balanced in those pillars and what that suggests about temperament, strengths and recurring pressures.
No. We read your chart as a description of tendencies and cycles, not as fate. The three-year map shows which themes your chart emphasises in each period, as material for reflection. It does not say what will happen.
Your birth date, birth time (as exact as you can) and birth city. If you don't know your birth time, tell us. We'll read the three pillars we can calculate and say clearly what that leaves out.
A PDF of about 2,000 words. It contains your four-pillars chart, an analysis of its structure (day master, ten gods, overall pattern) and a three-year cycle map. You can then send written follow-up questions for 14 days.
Within 48 hours of receiving your birth details. If we are going to miss that, we will email you before the deadline.
TangoEra prepares each reading from your calculated chart, following the five steps on our Method page. We don't list titles or credentials we can't show you.
Tell us within 30 days of purchase. You can choose a free rewrite or a full refund. If you change your mind before delivery, we refund you in full. The full policy is on our refund page.
