What You Need

To calculate your Sun, Moon, and Rising signs, you'll need three pieces of information:

1. Birth date (month, day, year)
2. Exact birth time (as precise as possible — check your birth certificate)
3. Birth location (city and state/country)

💡 Pro Tip: If you don't know your exact birth time, you can still find your Sun and Moon signs. The Rising sign changes every two hours, so it requires precision.

Step 1: Find Your Sun Sign

Your Sun sign is the zodiac sign the Sun was traveling through on the day you were born. This is the most well-known placement in astrology and represents your core identity.

Sun Sign Dates

Zodiac Sign	Date Range
♈ Aries	March 21 – April 19
♉ Taurus	April 20 – May 20
♊ Gemini	May 21 – June 20
♋ Cancer	June 21 – July 22
♌ Leo	July 23 – August 22
♍ Virgo	August 23 – September 22
♎ Libra	September 23 – October 22
♏ Scorpio	October 23 – November 21
♐ Sagittarius	November 22 – December 21
♑ Capricorn	December 22 – January 19
♒ Aquarius	January 20 – February 18
♓ Pisces	February 19 – March 20

Note: The exact cusp dates can vary by a day depending on the year. For precision, use our calculator which accounts for leap years and solar longitude.

Step 2: Find Your Moon Sign

Your Moon sign reveals where the Moon was positioned at your birth. It changes signs approximately every 2.5 days, so you need your birth date — but not necessarily the exact time.

Why the Moon Matters

The Moon governs your emotional nature, instincts, and inner world. While the Sun shows who you are, the Moon shows how you feel about being that person. It's the second most important placement in your chart.

Quick Moon Sign Estimate

If you can't access a calculator, you can estimate your Moon sign by knowing it changes roughly every 2.5 days throughout the month. However, for accuracy, we recommend using our calculator:

Step 3: Find Your Rising Sign (Ascendant)

Your Rising sign — also called the Ascendant — is the zodiac sign that was rising on the eastern horizon at your exact birth moment. This is the most complex of the Big Three to calculate because:

• It changes approximately every 2 hours
• It depends on your exact birth time
• It depends on your birth location (latitude and longitude)

Why the Rising Sign Matters

The Rising sign shapes your outer personality — how you appear to others, your approach to new situations, and your physical bearing. It acts as a lens through which the rest of your chart is filtered.

Manual Calculation (For the Curious)

If you want to calculate your Rising sign manually:

1. Look up the Local Sidereal Time (LST) at your birth location and time
2. Convert the LST to the Right Ascension of the Ascendant (RA)
3. Find which zodiac sign corresponds to that RA using an ephemeris table

This requires specialized astronomical tables. For most people, using our calculator is the practical approach:

Common Questions About the Big Three

Why don't I relate to my Sun sign?

It's common! Your Sun sign represents your core identity, but your Moon and Rising signs heavily influence how that identity expresses. A Leo Sun with a Virgo Rising might appear quiet and analytical at first — the warm Leo core is there, just filtered through a Virgo lens.

Why do I need my birth location?

Your birth location (latitude and longitude) is necessary to calculate:

• The exact Rising sign (which sign was on the eastern horizon)
• House cusps (which areas of life each planet occupies)
• Moon sign with precision (the Moon moves quickly)

What if I don't know my birth time?

If you don't know your exact birth time:

• You can still find your Sun sign (just needs date)
• You can estimate your Moon sign (needs date, time helps)
• You cannot accurately find your Rising sign (needs exact time + location)

Consider ordering a birth certificate from your birth location's vital records office — it's the most reliable way to get your birth time.
