What is a birth chart?
The birth chart — also called the natal chart or sky map — is a representation of the sky as it was at the precise moment you came into the world, seen from your place of birth. On this circle sit the Sun, the Moon, and the planets, spread across the twelve zodiac signs and twelve “houses” that correspond to as many areas of life. In astrology, it's the most personal signature there is: two people born on the same day but at different times don't have the same chart.
A chart is often summed up by three key markers, easy to grasp and already very telling: the Sun, the Moon, and the rising sign. Our free portrait focuses on the two most structuring ones — the Sun and the rising sign — to give you a clear, useful reading, with no jargon.
Sun, Moon, rising sign: the three pillars
The Sun: your identity
The Sun is your sign — the one you give when someone asks “what's your sign?” It describes your core: your vital drive, what truly moves you, the direction you naturally lean toward. In love, your Sun says what you're looking for deep down and how you shine when you're fully yourself.
The Moon: your inner world
The Moon governs your emotions, your intimate sensitivity, your needs for emotional security. It's the part of you that isn't seen at first glance, the one that reveals itself in intimacy and in deep bonds. Knowing your Moon helps you understand what soothes you, what hurts you, and what your heart truly needs to feel safe. The exact calculation of the Moon requires the time and place of birth — that's the next step of a complete chart.
The rising sign: the image you project
The rising sign is the sign that was rising on the eastern horizon at the moment of your birth. It describes your spontaneous attitude, your first impression, the “mask” the world perceives first. It's what explains how two people of the same sign can seem so different. In love, the rising sign colors the way you approach others and seduce, on top of your Sun's nature.
Why cross the Sun and the rising sign
This is the whole point of the astrological portrait: your Sun says who you are, your rising sign says how you appear. When the two align, your personality is fully owned, unfiltered. When they differ, a fertile contrast is born — for example a tender Sun behind a more assertive rising sign, or a go-getter Sun tempered by a composed rising sign. It's precisely this blend that makes the way you love unique, and that no generic horoscope can capture.

How to read your astrological portrait
Read the Sun part first: do you recognize your core, your drives, what makes you come alive? Then move to the rising sign: does it match the image others reflect back to you? Finish with your love signature, which weaves the two together. A birth chart is not a fixed destiny: it's a mirror to understand yourself better and make love choices more aligned with who you truly are.
Frequently asked questions
What is a birth chart?
A birth chart (or natal chart) is a snapshot of the sky at the exact moment of your birth: the position of the Sun, the Moon, and the planets across the twelve zodiac signs, seen from your place of birth. It's the most complete astrological ID there is. Its two most telling pillars are the Sun (your sign, your core identity) and the rising sign (the image you project).
How do you make your birth chart for free?
For a first astrological portrait, two pieces of information are enough: your sun sign and your birth time. Our tool then composes your Sun (who you are) and your rising sign (the image you give off), followed by your love signature. The result appears right away, for free and with no sign-up.
What's the difference between Sun, Moon, and rising sign?
The Sun is your sign: your deep identity, your vital drive. The Moon describes your emotional world, your need for security, your intimate sensitivity. The rising sign is the sign that was rising on the horizon when you were born: it describes your spontaneous attitude, your first impression, the social “mask” others see first. The Sun – Moon – rising trio forms the heart of your birth chart.
Is the astrological portrait accurate without the exact place and time?
Our portrait is a consistent approximation based on your sign and your time slot. For a birth chart accurate to the degree — with the Moon, all the planets, and the twelve houses — you need the exact time AND place of birth, because the Earth's rotation shifts the rising sign roughly every two hours. If you're unsure between two slots, read both: one will resonate more.
What's the point of knowing your birth chart in love?
Your birth chart sheds light on how you love: what your Sun is truly looking for, and how your rising sign colors the way you approach others. It's a kind mirror to understand yourself better, spot your emotional patterns, and identify the kind of partner you truly thrive with.
