Free birth chart and natal chart calculator
A birth chart is the sky at the moment you were born, mapped onto twelve houses. This calculator draws that natal chart from your date, time and place — then reads it, instead of stopping at a pretty wheel.
Free, no sign-up. Every calculation runs in your browser — your birth date, time and place are never sent to a server.
Birth chart, natal chart, astrology chart
Three names for one map. “Natal chart” is the European/US term; “birth chart” is the search most people use; “astrology chart” is the same drawing. This page is the Western-facing calculator. The Vedic how-to is birth chart reading; Indian kundli language is kundli analysis.

What must be on a real natal chart
- All planets (and, in Vedic mode, Rahu and Ketu)
- Ascendant (rising sign) and house cusps — whole-sign in Vedic; Western wheel with aspects
- Dignity: own sign, exaltation, fall, detriment
- A reading path: houses for life areas, then timing (transits; Vimshottari if you use Vedic)
Sidereal vs tropical in one sentence
If your Western Sun is mid-Taurus, your Vedic Sun is usually still in Aries. That 24° gap is precession, not a bug. Pick one system per reading; mixing them in the same sentence is how people decide astrology is random.
Birth chart future prediction
The chart is the map; the future question is the map plus time. On the Vedic side that means dashas you can slide to 2027 and beyond. That conversion path — birth chart future prediction — lives on future prediction by date of birth, not a second copy of this page.
Compatibility (two charts) is kundli matching. A sun-sign explainer is not this page; a personalized horoscope is.
Common questions
- Is the birth chart calculator free?
- Yes. No sign-up and no limit on charts.
- What is the difference between a birth chart and a natal chart?
- None. Natal chart is the same map under the Latin name.
- Do I need my exact birth time?
- For the rising sign and houses, yes. Without time you can still see the planets’ signs that day; you cannot honestly house them.
- Is this a Western or Vedic birth chart?
- Both modes are in the app. This page explains the shared idea. Vedic vocabulary and dashas are on the kundli and birth-chart-reading guides.
