The sky you were born under, on a dial you can turn.
Charting Stars is an astrology observatory with a Dial you can turn from 1850 to 2100. Cast your free Big 3 — Sun, Moon and Rising — or choose a paid written reading.
Which reading is right for me?
It depends on how much you want read. If you only want your Sun, Moon and Rising, the free Big 3 chart is enough. If you want your whole natal chart explained, with every planet by sign and house (houses need your birth time), dignity, sect, lots and aspects, the AI Natal Report ($19.99) is a one-time Hellenistic reading of about 3,000 words. If you also want love and relationships, career and vocation, and the next three months of dated transits from the same chart, choose the Premium Natal Reading ($49.99). Vedic and Three-Tradition (with BaZi) readings are separate.

Common questions.
What makes this different from a sun-sign horoscope?
We compute the full chart from your exact birth data, then cross-reference Hellenistic dignity, BaZi four-pillars, and the Vedic sidereal layer. The signature is what all three systems agree on — not any single layer.
Do I need to know my birth time?
Ideally yes. A birth time off by 30 minutes can shift the Ascendant a full sign and invalidate the angular-house interpretation, so please don't guess one. If you don't have it, tick “I don't know my birth time”: the free chart is cast for local noon and shows your Sun and Moon — naming both Moon signs if the Moon changed sign that day — and leaves Rising out. Check your birth certificate or hospital records for the time; paid readings need one.
What do I actually receive?
The free preview gives you your Big 3 — Sun, Moon, and Rising — instantly. The full wheel and every placement come with the paid readings, which range from a $19.99 AI natal report (~3,000 words, generated in minutes) through a $240 three-tradition synthesis, to a $420 extended reading (68 pages plus ~40 minutes of narrated audio). The $680 annual retainer is currently waitlist-only.
Cast your chart.
Four inputs. The sky's exact state at your birth, computed instantly — your Big 3 preview is free, no account required.
We need four
coordinates.
Accuracy matters. A birth time off by 30 minutes can shift the Ascendant by a full sign and invalidate the primary axis of interpretation. Check your birth record where possible. No time at all? Tick “I don’t know my birth time” and we cast your Sun and Moon for local noon, flagging the Moon if it changed sign that day, instead of guessing a Rising sign.

The questions people ask most, each answered by the engine on its own page.
Three doctrines, one delineation.
Each tradition's testimony is set beside the others with its evidence named: agreement where the facts support it, tension where they don't. No sun-sign shortcuts.
Dignity & sect — the oldest logic still holds.
Every placement is weighed by domicile, exaltation, bound, triplicity, and sect before a word is written. We compute the Lots of Fortune and Spirit, release both through zodiacal releasing, and carry each planet's condition into the reading so that weak testimony doesn't masquerade as strong.
Elemental chemistry, not symbolism.
The Four Pillars chart (年月日时) maps Heavenly Stems, Earthly Branches, and luck pillars across ten-year cycles. We isolate the Day Master, name every stem's Ten God relation to it (hidden stems included), tally the five elements, and set the luck and annual pillars out as a timeline — not a vibe.
Convergence, counterweight, and timing.
The three charts are laid side by side as data first: each tradition's element emphasis, the years their periods turn, and the Ascendant ruler beside the Day Master. The reading then names, theme by theme, the fact from each tradition it rests on, where they converge, where a counterweight pulls the other way, and when there is no clear cross-tradition conclusion at all.
A sample delineation.
Below: a worked specimen in the house style — how independent doctrines converge on a single testimony about the native.
The overbuilt tenth house.
Testimony converges. Saturn in domicile in the tenth whole-sign house, 3.7° from the MC (Hellenistic) + a 庚 Yang Metal Day Master on the 庚寅 day pillar (BaZi) — two independent systems return the same signature: duty treated as architecture.
The native builds frameworks, takes on visible responsibility early, and mistakes scaffolding for soul. The wheel sharpens the point: the Lot of Fortune falls at 1°45' Aquarius — a tenth of a degree from Saturn, in that same tenth house. Livelihood and taskmaster share one seat; career is not what this native does but where their weather happens.
The BaZi layer adds nuance: the month stem 己 stands to the Day Master as Direct Resource (正印) — earth feeding metal, the appetite for structure fed from birth. Practical translation: the native's instinct to fortify is overdeveloped, their capacity to put the tools down under-rehearsed. Rest is a discipline to be learned, not a reward to be earned.

How Charting Stars Dates a Transit, and How Close It Gets
People reasonably ask where the timeline's dates come from and how far to trust them. This is the whole answer, including the retrograde-loop rule, the Pluto limit and why angles are dated to the day.
The BaZi Day Master, Explained for a Western Reader
A Sun sign comes from where the Sun sat on the ecliptic. A Day Master comes from a sixty-day calendar cycle and a five-element tally. Same job, entirely different math, and it changes how the whole chart reads.
