Free Birth Chart Calculator
Your birth chart maps where the Sun, Moon, and every planet stood at the exact moment you were born. Enter your birth date, time, and place to generate it, then explore optional overlays like asteroids, fixed stars, and Vedic placements once your core chart is up.How it works ↓

Enter your birth date, time, and place to generate your natal chart, the map of where every planet stood at the moment you were born.
This is the chart to start with
Your core wheel shows the Sun, Moon, and Ascendant, all planets, the aspects between them, and house placements, using Placidus houses and the tropical zodiac by default. This is the same base chart nearly every other tool on the site builds on or compares against.
If a technique you have read about needs a different house system or zodiac, this is still the right starting point, the overlays and related tools below build from this same birth data.
Asteroids and fixed stars are already turned on
Two extra layers are included in your chart by default: asteroid placements and fixed-star conjunctions. You do not need to enable anything to see them. They are part of the standard view, positioned alongside the planets and aspects.
Four more layers are one click away
Beyond the default view, you can switch on a draconic chart (positions relative to the Moon's nodal axis), a Vedic overlay with sidereal placements and nakshatras, an antiscia overlay (mirror points across the solstice axis), and a sect-and-essential-dignity table (day/night chart plus classical rulership scoring).
Each of these is off by default because they answer a more specific question than the core wheel does. Turn one on when you already know what you are looking for; leave them off if you just want the standard reading.
Placidus and tropical are the defaults, not the only lens
If whole-sign houses or a sidereal zodiac are the primary frame you want to read from, rather than a secondary overlay on top of this chart, a dedicated whole-sign or sidereal chart tool will suit that better than toggling overlays here.
How to read the wheel
Start with the Sun, Moon, and Ascendant signs, then move to the aspects between planets, then to house placements. Treat any overlay you have switched on as an additional layer to check after the core reading, not a replacement for it.
Frequently Asked Questions
What do I need to calculate my birth chart?
Your birth date, time, and place. Time and place matter because they determine your Ascendant and house placements, not just your planet signs.
Do I need my exact birth time?
For Sun and Moon sign placements, an approximate time is usually fine. For your Ascendant and house placements, you need your exact birth time, even a few minutes can shift the Ascendant into a different sign.
