How to use it
- Enter your Date and Time of birth and your Place. If you do not know the time, tick I do not know the time; Saturn is then taken at 12:00 local time.
- Click Calculate. The natal Saturn position is shown first, followed by the table of passes.
- Read the Age and the Saturn moves column: a pass marked Retrograde is a backward pass over the same place.
- Use the Date and time column in the birth place's time zone to see the exact moment each pass happens.
What a Saturn return is
Saturn takes about 29.5 years to go once round the zodiac. A Saturn return is the time it comes back to the position it held when you were born, traditionally read as a time of review and of responsibility. Most people have a first return around age 29 or 30 and a second around 59.
Because Saturn turns retrograde, it often crosses the same place three times in about a year: once direct, once backwards and once direct again. The table lists all of these crossings, not only the first.
How the dates are found
The calculator follows Saturn's longitude from one day after birth to about age 65, with astronomy-engine. Each time the longitude passes the natal value it finds the moment to the second, by bisection. Saturn's turning points are found as well, so that each piece of motion is monotone and no pass is missed.
The age is the time since birth in years of 365.2425 days. The direction is Saturn's motion on that day, and the return number is counted from the nearest multiple of the 29.46-year period.
What this does not cover
- The other planets' returns, or the progressed chart; the birth chart calculator shows the natal positions for comparison.
- The effect of a Saturn return on a life. The dates are astronomy; what they mean is a matter of tradition and of your own reflection.
Worked example: New York, 4 July 1990, 14:30
Saturn was at 22°45′ Capricorn at birth, moving backwards. It passes that place again on 5 December 1990 at 03:37 New York time, moving forwards; that is an early pass, not a return.
The first return is on 12 January 2020 at 07:07, at age 29.5, when Saturn is direct. The second return has three passes: on 15 February 2049 at 15:29 (direct), 3 August 2049 at 12:20 (retrograde) and 13 November 2049 at 06:30 (direct), at ages 58.6, 59.1 and 59.4.
Frequently asked questions
When is my first Saturn return?
It is the pass nearest to age 29.5. The table labels it First return, and the age column shows the exact age at that moment, so you can compare it with your birthday.
Why are there three dates close together for one return?
Saturn turns retrograde when seen from the Earth, so it can cross the same place forwards, backwards and forwards again within about a year. These passes all belong to the same return.
Why does the time of birth matter for Saturn?
Saturn moves only about 0.03 degrees a day, so a few hours of error hardly matter. Without a time the calculator uses 12:00 local time, which is accurate enough for the dates.
What is the pass in the first months after birth?
Saturn can be retrograde at birth and then come back over the same place a few months later. The table lists it as an early pass, so it is not confused with a return.
Does this calculator keep my birth details?
No. The date, time and place are used in your browser and are not stored or sent to us.
