About · Four Pillars

What the four pillars are

Four Pillars is the branch of Chinese astrology that reads a person from the moment of birth rather than from a question. The year, month, day and hour each become a pillar, and every pillar is written as a pair of characters: a Heavenly Stem above an Earthly Branch. Ten stems and twelve branches combine into a cycle of sixty, which is why the same pairing only returns every six decades.

The day pillar is the one most readers care about. Its stem is the Day Master, the character that stands for you in the chart, and everything else is read in relation to it. Two people can share a year and a month and still lead very different charts, because the day and the hour are what make the reading personal.

Filling in your birth details

Enter the local clock time at the place you were born, not UTC. If you know the city, pick it and the form supplies the longitude for you; if you do not, type the longitude yourself and set the UTC offset that was actually in force on that date, daylight saving included. The chart converts this to true solar time before deciding the hour pillar, because the traditional hour boundaries follow the sun rather than the time zone.

If your birth hour is unknown, leave the time blank. The chart marks the hour pillar as missing and reads the remaining three, which still carry most of the structure. Names are optional and are only used to label the report you print.

Reading your chart

The report opens with the four pillars and the Day Master, then shows how the Five Elements, Wood, Fire, Earth, Metal and Water, are distributed across the chart. An element that is plentiful is not automatically good, and one that is scarce is not automatically bad. What matters is balance, and what the Day Master needs. The personality section describes the temperament of the Day Master; the lucky guide lists the elements, colours, numbers and directions traditionally used to restore that balance. Treat the whole thing as a mirror rather than a clock.

Questions people ask

Does the chart leave my browser?

No. Every calculation, the pillars, the Five Elements and the solar-time conversion, runs locally in your browser. Your name, birth date and place of birth are never uploaded, and there is no account and no database behind this page.

I was born close to midnight. Which day is correct?

Traditional practice starts a new day at the hour of Zi, around 23:00, rather than at midnight. If you were born between roughly 23:00 and 00:00, the day pillar belongs to the following day. Try both: a one-day shift usually produces a different Day Master, and the one that describes you better is a useful signal.

Why does the chart ask for a city or a longitude?

Because the hour pillar depends on where the sun actually stands, not on the clock. Two people born at the same clock time in different cities can fall into different hour branches. Without a location the chart falls back to plain clock time, which is close enough for most purposes but not exact.

Is this a prediction about my future?

No. The report is produced for cultural interest and self-reflection. It is not a forecast, not a diagnosis and not advice of any kind. Read it as a structured description of temperament and tendencies: useful as a mirror, unreliable as a clock.
