Rising sign calculator: what's your rising sign?

Your rising sign, also called your Ascendant, is how you come across and the first impression you leave. Get yours to the exact degree from your birth date, time, and place. The rest of your birth chart is right below.

When were you born?

Your date tells us which sign the Sun and each planet were in. It's the first piece of the calculation and isn't used for anything else.

What time were you born?

Your birth time matters most for your rising sign. As the Earth turns, the Ascendant moves into a new sign every one to two and a half hours, depending on the sign. You'll find your birth time on your birth certificate.

Where were you born?

Start typing your city and pick it from the list. That's how we get the exact coordinates of where you were born.

We set the time zone for your date and place automatically, including any historical changes.

Your birth chart is ready.

What is a rising sign?

Your rising sign, also called your Ascendant, is the zodiac sign that was rising on the eastern horizon at the exact moment you were born, as seen from your birth city. It's the starting point of your birth chart: the twelve houses, one for each area of your life, are counted from there.

It's calculated from three details: your birth date, time, and place. Of the three, the time matters most, because the horizon turns with the Earth and the Ascendant moves through all twelve signs every day.

What this calculator shows you

  • Your rising sign and the exact degree of your Ascendant, right at the top of your results.
  • Your Descendant and Midheaven, two more angles of your chart. The Descendant is about what you look for in another person, and the Midheaven is about your career and your public image.
  • Your full birth chart below: all ten planets with their signs and houses, the twelve houses, and the aspects (the angles your planets form with each other).

Everything is calculated from NASA ephemeris data, the tables NASA's Jet Propulsion Laboratory publishes to track where each planet is at any moment. We also use the time zone your city followed on the day you were born, including daylight saving time as it applied back then. Your results appear in a few seconds, with no card needed and no account to create.

Why your exact birth time matters so much

The Sun takes about a month to cross a sign, and the Moon a little over two days. The Ascendant crosses one in anywhere from one to two and a half hours, depending on the sign. That makes it the part of your chart that depends most on the clock, and also the one most likely to be off when your birth time is approximate.

If your Ascendant lands in the first or last few degrees of a sign, double-check your birth time: you're close to a sign change. If it lands in the middle of the sign, being a little off on the time won't move it into another sign.

How to read your rising sign

Your rising sign describes how you show up and how you walk into new situations: the first impression you make, the way you carry yourself, and how you get things going. It doesn't replace your Sun sign. It colors how your Sun sign comes across. If you're a Leo Sun with Virgo rising, you shine just as bright, but you tend to walk into the room a little more carefully.

The planet that rules your rising sign is known as your chart ruler, and the sign and house it sits in point to where your energy tends to go. Scorpio, Aquarius, and Pisces each have both a classical ruler and a modern one. That's what our birth chart reading is for. Built on this same calculation and reviewed by astrologers, it reads all of this alongside the rest of your chart.

Frequently asked questions

Can I find my rising sign without my birth time?

Not reliably. Your rising sign comes from the Ascendant, the degree of the zodiac that was rising on the eastern horizon at the minute you were born. That point moves through all twelve signs in a single day. With no birth time at all, it could be any of the twelve. With a rough window, like sometime in the morning, you can narrow it down to a few signs, but you can't confirm which one is yours.

How often does the rising sign change?

The rising sign changes about every two hours on average, but not every sign takes the same amount of time to rise. Seen from most of the US, Pisces and Aries rise in a little over an hour, while Leo, Virgo, Libra, and Scorpio take about two and a half hours each. In the Southern Hemisphere, it's the other way around. That's why, if you were born close to a sign change, a few minutes' difference in your birth time is enough to change your rising sign.

What's the difference between my rising sign and my Sun sign?

Your Sun sign depends on the day you were born, and everyone born in that same stretch of the year shares it. Your rising sign, also called your Ascendant, depends on the time and place you were born, so two people born on the same day can have different rising signs. The Sun is about who you are at your core and where you're headed, and your rising sign is about how you step into things and how people see you at first.

What is the Descendant?

The Descendant is the point opposite your Ascendant, the degree that was setting on the western horizon when you were born. It always falls in the sign opposite your rising sign, at the same degree. In Placidus, the house system we use, it marks the start of the 7th house, the house of partners and one-to-one relationships.

Why do I get a different rising sign on another calculator?

A different rising sign almost always comes down to the birth time or the time zone. If the time you enter isn't exact, your Ascendant shifts. The other common cause is historical daylight saving time: some calculators apply your city's current time zone rules instead of the ones in effect on the day you were born. This calculator uses the rules from that day. And if the other calculator uses the sidereal zodiac, the one Vedic astrology uses, everything shifts by about 24°, and your rising sign usually changes. This one uses the tropical zodiac, the one Western astrology uses.

Where can I find my birth time?

Check your birth certificate, your hospital records, or the vital records office in the state where you were born. If all you have is an approximate time from your family, use it and treat your rising sign as tentative, especially if your Ascendant lands in the first or last few degrees of a sign.
