Free Birth Chart Calculator With Houses
Planet signs and degrees · Placidus houses · 3D aspects
Calculate your natal chart from your birth date, recorded local time and birthplace. See planetary signs and degrees, house cusps and measured aspects, then read the result or explore a printable poster. No sign-in is needed to start.
For a birth chart with houses, enter the place where you were born and the clock time recorded there. The city resolves coordinates and the historical time zone; your current location is not a substitute. Houses and the Ascendant depend on the birth instant, so a guessed time can change the chart even when the birth date is correct.
Read the result in layers: first confirm the birth inputs, then note the Sun, Moon and Ascendant, then inspect the planet-and-house table. An aspect label describes a calculated angle, while the written interpretation is astrology. Use the methodology page when comparing our 3D angular aspects with a calculator that measures zodiac-longitude angles.
A free chart reading and a print-ready poster are different products. You can use the chart before deciding whether to buy a digital poster; preview the design and check its current price and file formats on the poster page. No physical print or frame is included in a digital download.

Birth chart FAQ
What is a natal chart reading?
The chart is the calculated map; the reading is an interpretation of it. Start with the Sun, Moon and Ascendant, then look at their houses and aspects. Natal Echo provides both the chart data and a written astrology reading, so you can check which placements the explanation refers to.
How accurate is this natal chart?
Check the birth date, AM/PM, recorded local time and selected birthplace first. A mistyped time can change the Ascendant and houses. The calculation can only be as specific as those inputs; a precise degree on screen does not make an estimated birth time exact.
What does a natal chart show?
It lists the Sun, Moon and planets by zodiac sign and degree. With a known birth time, it also shows the Ascendant and house placements. Aspect labels identify angles between planets. Read those entries alongside the wheel when the symbols are unfamiliar.
Can I calculate my birth chart without my birth time?
Yes, use the unknown-time option with your birth date and place. The chart uses a labelled estimate; the Moon and any planet near a sign boundary can need a time check. Rising sign, houses and Midheaven are not reliable without a recorded birth time. A noon estimate does not establish every placement throughout the day.
Can I print or download my birth chart?
The result page includes options to save the wheel and download the written reading. A print-ready poster is a separate paid download, with SVG, PNG and PDF files. Review the poster preview, price and printing requirements before checkout.
Which house system does this calculator use?
The default is Placidus. At polar locations where that system cannot be calculated, the engine can return Porphyry houses and label the system used. Check that label before comparing another chart. Switching house systems can move a planet to another house without changing its zodiac sign or degree.
Are the aspects calculated in 3D?
Yes. The aspect calculation uses planetary longitude and latitude to measure angular separation in the sky. A longitude-only calculator measures along the zodiac instead. Two tools can therefore give different aspect orbs even when their listed zodiac degrees agree; our methodology guide explains the distinction.
What do I enter for a free birth chart with houses?
Enter your birth date, recorded local birth time and birth city, then select the matching location. Review these inputs before interpreting the house table. If you do not know the time, use the unknown-time option rather than inventing one.
Is the printable poster included with the free chart?
The chart and its reading are separate from the paid print-ready poster. Open the poster preview to check the design, current price and download options before checkout. A digital poster does not include shipping or a frame.
How can the same zodiac degrees give different aspect orbs?
Longitude and angular separation measure different things. In a simple geometry example, two positions at 0° longitude with latitudes of 0° and 5° share a zodiac degree but are 5° apart in the sky. Natal Echo’s 3D aspects use both coordinates. The 2D-versus-3D guide and methodology page explain why a longitude-only report can list a different orb.
