Birth Chart Calculator
A birth chart, or natal chart, is a map of the sky at the exact moment and place you were born. This calculator places your Sun, Moon, Rising, and every planet by sign, and adds houses when you give an exact birth time and birthplace.

quick answer
What a birth chart shows
signs and houses
Planets show what is at work. Houses show where it plays out in life. Houses need an exact birth time and place to be correct.
a starting map
The chart is a map to read, not a verdict. WooWoogle treats it as symbolic language for self knowledge, not prediction or proof.

Why birth time and place matter
Rising and houses need time
The Rising sign and the house layout depend on the exact minute and location of birth. Without them, this calculator still shows planetary signs but withholds houses and Rising instead of guessing.
Place sets the timezone
Your birth time is local. The calculator needs the correct timezone and coordinates to build the chart. A resolved birthplace gives both.

How WooWoogle keeps the chart honest
Calculation uses the chart engine
This page calls the same Western astrology engine as the full app, powered by the astronomy engine library. Missing time or place downgrades the result to labeled signs, never a fabricated Rising or house.
Meaning comes from sign nodes
Placement copy is grounded in WooWoogle knowledge nodes, which cite the Western astrology source stack including Brennan, Lilly, Ptolemy, and Arroyo.
Planetary signs are solid from the birth date, though the Moon and fast points can shift on some days without a birth time. Rising sign and Whole Sign houses require exact birth time plus birthplace.
Questions people ask
Can I get my birth chart without a birth time?
Partly. Planetary signs are calculated from the date, so you still get most of the chart. But the Rising sign and the houses need an exact birth time and place, so this calculator withholds them rather than guessing.
What is the difference between a birth chart and Big 3?
Your Big 3 is just the Sun, Moon, and Rising. A full birth chart adds every other planet by sign, and the houses when a birth time and place are known.
Which house system does this use?
Whole Sign houses, the oldest and most widely taught system, calculated only when an exact birth time and birthplace are supplied.
Why is my chart different on other sites?
Usually timezone and house system differences. The chart depends on exact local time and coordinates, and sites vary in how they handle both. WooWoogle labels its confidence instead of hiding the gaps.
Is a birth chart the same as a horoscope?
No. A birth chart is the fixed map of your birth sky. A horoscope is a short forecast, usually based only on your Sun sign. WooWoogle focuses on the chart, not daily predictions.
