OmenHall Birth Chart
This is your stable astrological baseline: birth data becomes planets, angles, houses, and aspects with an explicit precision boundary. The profile does not forecast today — it becomes the foundation for Horoscope, Transits, Compatibility, and Year Map.

This room's core question
How is my stable baseline structured?
I want to understand my natal baseline
You confirm birth data and watch planets, angles, houses, and aspects assemble from exact time and place. This is not a forecast but a map of natal architecture.
What you need
Birth date, calendar, timezone, and place; time may be exact, approximate, or unknown and is handled as a distinct authority model.
Horizon
stable baseline · infrequent foundational calculation
Proof before the full scroll
Reference placements, Ascendant/MC with exact time, and calculation provenance.
What you receive
Big Three, planets, houses, aspects, elements, strong axes, resources, tensions, and an explanation of precision level.
Why return
The profile is purchased infrequently, but becomes the foundation for Transits, Compatibility, Year Map, and personal Horoscope.
Why this is a separate room
This is “who am I in this system,” not “when should I act” or “what happens between two people.”
independent product
When to choose this room
A foundational astrological passport: one precise calculation becomes the stable baseline for the other personal sky rooms.
Best for
- When you want natal architecture rather than a forecast.
- When you need one reusable profile for Transits, Compatibility, and Year Map.
- When you want the effect of birth-time precision shown honestly.
Not this room's job
- Does not answer “what will happen today.”
- Must not claim exact houses or angles when birth time is unknown.
What the full result contains01 02 03 04
Planets and houses
Placements, houses, and strong areas of the chart.
Aspects and elements
Planetary links, elemental balance, and recurring patterns.
Resources and precision
Practical synthesis with an explicit precision boundary.
Next reason to return: Return not to rebuy the profile, but to reuse it in Transits, Compatibility, or Year Map.

first result
Natal Proof
Sun and Moon
Reference placements appear immediately after calculation.
ASC / MC
Shown only when birth-time precision and coordinates allow it.
Houses
Twelve cusps are never substituted when geometry is not reliable enough.
Aspects
Major aspects and orbs belong to the fixed snapshot.
What this result does not claim: Unknown birth time never becomes an invented Ascendant.

Choose person
Data comes from the account or can be entered once for another person.
- 02
Confirm authority
Exact time permits precise geometry; approximate time becomes a range; unknown time becomes the full local-date interval without a hidden noon.

Assemble chart
Planets, Ascendant/MC, houses, and aspects are built from calculation, not model prose.

Open profile
The scroll explains a person's stable structure without replacing it with a current forecast.
profile
Build Birth Chart
Birth date, time, and place are fixed as input data, not as a reason for fatal labels.
authority
Natal chart technologies
Exact, approximate, and unknown time use distinct authority models; Ptolemy, Valens, Lilly, and Jyotisa are not mixed into OmenHall Modern.
engine
Chart grammar
Planet, house, and aspect turn the chart into a readable formula: what acts, where, and how.
timing
Future transits
The birth chart becomes the base for personal transits, yearly forecast, compatibility, and calendar.
verifiable profile
Build Birth Chart
Birth evidence, calendar, and civil time are fixed first; then the server calculates the sky. Exact time can yield exact geometry, approximate time propagates through a declared ± interval, and unknown time becomes a full-day envelope without invented 12:00.
who is this for
Whose Birth Chart is this
Your data comes from your account. Another person can be used once or saved separately. Source data is fixed before interpretation.
Search uses OmenHall's local GeoNames cities500 copy, CC BY 4.0. No metered external geocoder is called for each search. GeoNames
Precise place coordinates (advanced)
Coordinates are needed for exact houses, angles, and synastry overlays. They are not fetched again for every calculation: OmenHall stores the resolved place in the Person Passport. The local GeoNames gazetteer supplies coordinates and IANA timezone without a paid API; manual entry remains a fallback for rare places.
Without sign-in, data is not saved: you can use a one-time profile. After sign-in, Me and Saved Person become available.

What these birth data can actually support
Planetsrange
Calculated as a full-local-date interval, never with invented noon.
Aspectsrange
Interval mode shows sampled stability rather than false continuous proof.
ASC / MCneeds data
An exact point requires exact time + coordinates.
Housesneeds data
Unknown time never receives one invented house.

Temporal house system; polar geometry fails closed instead of silently switching systems.
One-time profiles are never stored automatically.
The full recorded local-date interval is calculated: stable/possible placements are shown, but no single Ascendant, MC, or exact house is promoted as fact.
An unknown-time envelope needs the birth date and the place's IANA timezone; no clock time is needed or invented.
Natal authority
After calculation, this area shows either an exact chart or interval authority. OmenHall does not insert demo placements as personal data before calculation.
Birth date
Needed for Sun, Moon, and planet positions.
Store as a private profile field.
Birth time
Needed for houses, Ascendant, MC, and precise Moon.
If time is unknown, the answer must honestly switch to unknown-time mode.
Birth place
Needed for timezone, coordinates, and houses.
Do not show publicly or use for ads.
Profile name
Needed for archive convenience: me, partner, child, project persona.
The name may be a nickname.

The table calls Reality Engine and shows calculated planetary placements, tropical signs, and major aspects before interpretation. Demo placements are no longer substituted.
