Saturn Return Calculator
Saturn takes 29.4571 years to go once around the Sun, and a Saturn return is the point where it has completed one lap since the day you were born. Enter your birth date and this counts that orbital period forward once, twice and three times, and gives a six month window either side of each date. Saturn turns retrograde for part of every year and its orbit is an ellipse, so the exact crossing needs a real ephemeris and can land anywhere in that window. The orbit is astronomy; what the return is supposed to mean about your life is astrology, so take that part as entertainment.
