This question is likely referencing the concept of "planetary returns" in astrology.
In astrology, a planetary return occurs when a planet in your birth chart returns to the same position it occupied at the time of your birth. This is considered a significant astrological event, often associated with themes and challenges related to the planet in question.
The planet that returns when you turn 23 is Saturn. This is because Saturn takes approximately 29.5 years to complete one orbit around the Sun.
The Saturn return is generally seen as a time of significant personal growth and transformation. It can be a challenging period, but it also offers opportunities for self-discovery and maturity.
