Enter your birth date, recorded birth time and birthplace to calculate your Sun, Moon, Rising sign and planetary placements. Your name is optional, and no signup or payment is required. This free natal chart does not include houses or aspects.

What this free birth chart calculator includes

The result lists the Sun, Moon and planets from Mercury to Pluto, plus the Ascendant (Rising sign) and Midheaven. It shows signs and degrees, not houses or aspects. Interpretations are a starting point for reflection, not established facts about your personality or future.

Use a recorded birth time

The Rising sign depends on the time and place of birth. If you do not know your time, do not enter a guess and treat the result as certain. The Moon can also change signs during a day. Check the details you enter, especially AM or PM and the selected birthplace.

For a different topic, read the astrocartography line meanings guide. That guide explains symbolism; it does not calculate a personal location map.

Read your Sun, Moon and Rising signs together

Start with the method guide, then use the worked examples to see how three placements can interact. These are symbolic interpretations, not a personality diagnosis or a prediction.

Looking at your birthday year?

A natal chart and an annual chart answer different questions. Read solar return chart vs natal chart for the timing, inputs and limits of each. This calculator produces natal placements, not a solar return.

Read your chart ruler

After finding your Rising sign, follow its ruling planet. These guides use signs, not assumed houses. An uncertain birth time can make the Rising sign and ruler uncertain too.

Understand a solar return placement

Already have a calculated solar return chart? These guides explain selected annual placements. The free calculator on this site produces natal signs and degrees, not solar returns or houses.

Birth chart calculator questions

Is this birth chart calculator free?

Yes. You can calculate your natal planetary placements without signing up, entering an email address or making a payment.

What details do I need to calculate my birth chart?

Enter your date of birth, recorded birth time and birthplace. Your name is optional. Time and place are needed to calculate the Rising sign and Midheaven accurately.

What if I do not know my exact birth time?

Do not invent a time and treat the result as certain. The Rising sign and Midheaven are time-sensitive, and the Moon can change signs during a day. Check a birth record or another reliable source before calculating the full result.

Is a birth chart the same as a natal chart?

Yes. Birth chart and natal chart are two names for a map of planetary positions at the time and place of birth.

Does this calculator include houses and aspects?

No. It gives planetary signs and degrees, the Rising sign and the Midheaven. It does not calculate houses, aspects, a solar return or an astrocartography map.
