Birth chart
Your natal sky
The exact sky of your birth, precisely calculated and read as an inner portrait: your drives, your ways, your areas of life.
Understanding your birth chart
What the chart shows
A birth chart is the position of the Sun, the Moon and the planets in the zodiac at the moment you were born, seen from your place of birth. Each planet falls in a sign (a way of being) and in a house (an area of life). The aspects, the lines at the centre of the wheel, connect planets to each other: tensions to work with or natural harmonies.
Why time and place matter
The sky turns by about one degree every four minutes. Your birth time and place therefore set the Ascendant, the Midheaven and the twelve houses. Without a birth time, the planets' signs and their aspects remain reliable, but the Ascendant and houses cannot be calculated: the chart says so clearly instead of guessing.
How it is calculated
Positions are calculated with Swiss Ephemeris, the reference used by astronomers and astrologers, in the tropical zodiac. Houses use the Placidus system (Porphyry beyond the polar circles, where Placidus is undefined). The time zone and daylight saving time of your birthplace are applied automatically. No AI is involved in the calculation.
Frequently asked questions
Is the birth chart really free?
Yes. The calculation, the wheel, the explanation of each position and the chart PDF download are free and need no account. Only the full report, far more developed, is paid: 3 credits, no subscription (1 credit = 1 full reading). A free account lets you save your birth profiles and find your reports again.
What is in the full report?
Around fifteen pages on your chart: every planet in its sign and its house, with what carries you, what it costs you and a path; the Ascendant and the Midheaven; the balance of your chart; the dialogues between your planets. It downloads as a PDF, as many times as you like, from your account.
I don't know my birth time. What can I do?
Tick "I don't know my time of birth": you get the planets in their signs and their aspects. The Ascendant and houses need the exact time. It is often recorded on your full birth certificate.
What is the difference between the birth chart and the Introspection reading?
The birth chart shows the map and explains each element on its own. The Introspection reading weaves these elements together to answer a specific question you ask, in psychological terms.
Is astrology a science?
No. The astronomical calculation is exact, but astrology remains a symbolic lens, not a predictive science. Filigra uses it as a support for self-reflection, never to announce events.
