If you don't know your birth time
Without a birth time, the calculator checks Pluto's sign across the whole local birth day. If it changes, you get both possible readings and the approximate local change time. The degree, house and personal map links need a birth time; a sign-only share card is available when the sign is certain. You can print or save the result as a PDF.
Your Pluto sign and your generation
Pluto was discovered in 1930 by Clyde Tombaugh, and it is the slowest of the planets astrologers use. It takes about 248 years to go around the zodiac, and its orbit is so stretched that it spends anywhere from about 12 years in a sign (Scorpio) to about 33 (Taurus). Everyone born in the same stretch shares a Pluto sign, so astrologers read it as a generation's theme: what that generation is driven to break down and rebuild, from the upheavals of home and homeland for those born with Pluto in Cancer to the remaking of institutions for those born with it in Capricorn.
The generations since 1912
Each row gives the birth years of one Pluto sign, counted from Pluto's first entry into the sign to its final exit; the years overlap because a retrograde loop can carry it back across the boundary. Pluto is retrograde about 44% of the time, for about five months every year.
| Pluto in | Born | Read as |
|---|---|---|
| Cancer | 1912–1939 | upheavals of home and homeland |
| Leo | 1937–1958 | a drive for recognition and self-expression |
| Virgo | 1956–1972 | remaking work, health and technology |
| Libra | 1971–1984 | new ideas of partnership and fairness |
| Scorpio | 1983–1995 | facing taboos and power head on |
| Sagittarius | 1995–2008 | questioning belief, with a global outlook |
| Capricorn | 2008–2024 | rebuilding institutions and economies |
| Aquarius | 2023–2044 | collective power and new communities |
Pluto is in Aquarius now: Pluto in Aquarius gives every date of the passage, which runs to 2044, and what astrologers read in it.
Pluto in your birth chart
Beyond its house, Pluto becomes personal through its aspects. When it touches your Sun, Moon, Venus, Mars or rising sign, astrologers read that part of your life as intense and transforming: a strong will, deep feelings, and a knack for rebuilding after loss. The birth chart calculator lists every aspect Pluto makes in your chart.
Why the house matters
Your Pluto sign is shared by millions; the house it fell in is yours. With a birth time, the calculator finds that house, which shows where Pluto's intensity plays out in your own life: the 7th house in close relationships, the 10th in career and public life, the 4th at home. That is where astrologers look for the power struggles, the deep changes and, in the end, the strength that Pluto brings.
How it is worked out
The calculator finds Pluto's position at your birth from the site's own ephemeris, the same one behind every chart here, and gives the dates Pluto entered and left your sign. Because Pluto loops backward for about five months every year, it can cross a sign boundary more than once, so a sign can have two or three sets of dates. Your details stay in your browser.
