One’s a guess.Three’s a pattern.

Wholechart computes your Western natal chart, your Chinese BaZi Four Pillars and your Pythagorean numerology from one set of birth details — then writes one reading across all three, with a score for how much they actually agree that day.

Free to download. One email to confirm, one the day it launches.

Chinese BaZi Four Pillars, the solar-term year boundary, and your Day Master.

Where the others stop

Most days, the three don’t agree.

That is the interesting part. Wholechart says so rather than smoothing it over — it names which system is the outlier that day, and what it is saying instead.

One system on its own cannot tell you whether it is describing your life or describing itself. Three can disagree — and a disagreement is information you cannot get from a single reading, however well written it is.

6 of the 8 ways three systems can land is a disagreement. That is arithmetic, not pessimism — and it is why a reading that never mentions one is hiding something.

What it computes

Every placement,
from one set of birth details.

Western astrology

Ten bodies placed to the exact degree
Whole-sign houses, anchored on your Rising sign
True-solar-time correction from your birth longitude
The transits moving against your natal chart

Chinese BaZi

Year, Month, Day and Hour pillars
The year turns at the solar term, not the lunar new year
Day Pillar advances at 23:00, late-Zi convention
Your Day Master and your Luck Pillars

Pythagorean numerology

Life Path, Expression, Soul Urge, Personality
Your Personal Year, Month and Day
Master numbers kept where the tradition keeps them
The convention it used, stated plainly

One birth, three charts

The same person, read three ways.

Example — not a real person. 14 March 1996, 06:42, Austin. Every value above was produced by the same engine the app runs, so you can check it against any calculator you like. The numerology seal is drawn from the number itself: six sides for a six.

Scored, not smoothed

An agreement score, every day.

Three readings are computed, then compared. The score is how much of the day’s account the three systems actually share.

A high score means the traditions converged and you can lean on the reading. A low one means they didn’t — and Wholechart tells you which one broke ranks instead of averaging the three into mush.

Example output

Western astrology expansive

the Four Pillars expansive

numerology consolidating

67%

2 of 3 systems agree. Numerology reads it differently — that split is the reading, not a fault in it.

Your data, about your days

Then the journal keeps score.

Read your day, then say whether it fit. One tap per system.

Wholechart keeps a running percentage for each of the three — Western, BaZi, numerology — so after a few weeks you can see which of them has actually been describing your life, and which hasn’t. It is your own record, reported back to you. The journal and the trend percentages are free.

Example — thirty days

Western astrology 71%

the Four Pillars 64%

numerology 48%

After a month of one-tap answers, this reader is being described best by the Western chart and least by the numbers. Nobody decided that — they did.

Built to be checked

Every chart is computed, not composed.

Solar terms, not the lunar new year

The BaZi year turns at the solar term, which is where the tradition actually puts it — not at the lunar new year, which is where most apps put it because it is easier.

The Day Pillar turns at 23:00

Late-Zi convention. If another app gives you a different Day Pillar for an evening birth, this is usually why — and Wholechart tells you which convention it used.

True solar time, from your longitude

Clock time is a political convenience and the sky does not keep it. The hour is corrected for true solar time at your birth longitude, equation of time included.

Whole-sign houses, everywhere

One house system, used consistently, and named. Where another calculator disagrees, the app says what changes if you use a different one.

Unknown birth time stays unknown

No birth time means no Rising sign, no houses, no Hour Pillar. Wholechart leaves out what genuinely cannot be known instead of guessing and hoping you will not check.

Same input, same output

The engine is a pure function with a pinned version — no clock reads, no randomness. The same birth details and the same engine version produce the same chart, and when the version does change, it says so.

The explanatory layer

It explains itself.

Why your Rising sign differs from your Sun. Which house system this app uses, and what changes if you use another. Why your Life Path can differ from another calculator’s.

It is all in the app, and all of it is free. A reading you cannot interrogate is just an assertion.
