Saturn sign calculator

If you don't know your birth time

Without a birth time, the calculator checks Saturn'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. Saturn return dates use noon as a reference and are marked approximate. You can print or save the result as a PDF.

What your Saturn sign says

Saturn is the farthest planet easily seen with the naked eye, and astrologers read it as the principle of time and structure: discipline, responsibility, limits, fear and, in the end, mastery. Traditional astrology calls it the greater malefic, the planet of hardship; modern astrologers more often call it the teacher. Your Saturn sign describes the lesson you meet again and again, and its house shows where you are tested and where, with patience, you build something that lasts.

In the traditional scheme Saturn rules Capricorn and Aquarius and is exalted in Libra. In Cancer and Leo, the signs opposite its own, it is in its detriment, and in Aries, opposite Libra, in its fall. Astrologers read those placements as the harder lessons, and often the ones that teach the most.

Saturn is in Aries, its fall, until April 2028: Saturn in Aries gives every date of the passage and what astrologers read in it.

Two and a half years in each sign

Saturn takes about 29 and a half years to circle the zodiac, so it spends about two and a half years in each sign. Every year it appears to move backward for about four and a half months, and around a sign change that loop can carry it back into the sign it has just left, sometimes for as long as seven months. The section below lists the birth dates for Saturn in each sign from 1930 to 2040; the calculator gives the exact dates Saturn entered and left your sign, with a table of its signs from five years before your birth to five years after.

Your Saturn returns

Saturn comes back to the degree it held at your birth around ages 29, 58 and 88: the Saturn returns. Astrologers read the first as the real start of adulthood, a time of taking stock and deciding what to build; the second as a turn toward legacy; the third as a time of wisdom. With a birth time, the calculator lists each return's exact dates, with all three passes when a retrograde loop crosses your Saturn degree, and the Saturn return calculator adds the whole return season and whether you are in one now.

Your Saturn lines on the map

Saturn has four lines on your astrocartography map, showing where it was rising, setting, overhead and underfoot when you were born. Places near them are read as places of hard work, responsibility and lasting achievement: demanding, but rarely wasted. Read about each one in the Saturn lines guide or see them on your free astrocartography chart.
