Planetary placements
Find your planets. Read the sky.
Twelve free calculators for the sign and exact degree of each placement. Worked out in your browser, so your birth details never leave it.
Calculators
Pick a placement
Each result gives the sign, the degree and minute, and the element. Birth time is optional everywhere except rising, midheaven and the big three.
Moon sign
Sign, degree, element and the moon phase you were born under.
Rising sign
Your ascendant: the sign rising in the east at the minute you were born.
Sun, moon & rising
Your big three in one result, each with sign, degree and element.
Saturn return
Every exact return date and your age at each, past and upcoming.
Venus sign
Sign and degree, retrograde at birth, and morning or evening star.
North node
Mean north node sign and degree, with the south node opposite.
Sun sign
The exact sun degree, which settles a birthday on a cusp date.
Lilith sign
Black Moon Lilith (the mean lunar apogee): sign and degree.
Midheaven
The MC: the sign and degree at the top of your chart.
Mars sign
Sign, degree, element and whether Mars was retrograde.
Mercury sign
Sign, degree, element and whether Mercury was retrograde.
Chinese zodiac
Animal and element, using the lunar new year date for your birth year.
How we calculate
Checked against NASA’s own tables
12″
Largest gap from NASA JPL
astronomy-engine (MIT licence) positions for the Sun, Moon, Mercury, Venus, Mars and Saturn on six dates, compared with JPL Horizons. Twelve arcseconds is under 1/300 of a degree.
Your birth place and its clock
Places come from GeoNames (CC BY 4.0), each with its time zone. Your browser works out the offset in force on your birth date, daylight saving included.
No birth time? Still an answer
If a planet changed sign on your birth day, you see both signs and the exact time it moved, instead of a guess.
Nothing leaves your browser
No account and no form sent anywhere. A share link keeps your details after the #, which browsers never send to a server.
