Birth data
Date, time and location let the calculator place planets, houses and angular axes in the right context.
Birth chart first, transits next
Birth chart calculator for AI astrology analysis
Your birth chart is the foundation for a useful transit reading. Astro Legacy uses your date, time and place of birth to calculate chart context before analyzing current planetary transits with AI-assisted interpretation.
Natal context
The chart becomes the reference point for current transits, aspect strength and timing.
AI synthesis
Instead of stopping at positions, Astro Legacy helps explain what the current transits emphasize.
Why the birth chart matters
A transit only becomes personal when it is compared with your natal chart. The same Saturn, Jupiter or Mars transit can describe different themes depending on natal planets, houses and angles. Astro Legacy keeps this context visible while presenting the results in a readable way.
- Calculate natal positions from birth data.
- Use houses and ASC/MC when birth time is known.
- Connect the natal chart with daily, weekly and monthly transit periods.
FAQ
Can I use Astro Legacy without exact birth time?
Yes. The app can run with an approximate noon time, but houses and ASC/MC will be less precise.
Does Astro Legacy only calculate a birth chart?
No. The birth chart is used as the base for transit analysis and AI-assisted interpretation.
