A transit is what happens when a planet in today’s sky forms a meaningful angle to a planet or point in your birth chart. Your chart is fixed at the moment you were born. The real planets keep moving. Transits compare the two, and astrologers use them to describe what a given stretch of your life tends to feel like.
Your birth chart is a snapshot of the sky at your first breath. It’s static: every planet stays where it was. A transit is the moving sky checking in with that snapshot. If Saturn today sits at the same degree your Moon occupied when you were born, you’re having a Saturn transit to your natal Moon. Saturn stands for tests, structure, and growing up. The Moon is your emotional self. So astrologers expect a period of emotional maturing: sometimes heavy, usually clarifying.
Transits are the reason astrology can talk about what’s happening now and not only who you are. Without them, a chart would be a portrait hanging on a wall. With them, it reads more like a calendar. If you need the basics first, start with what a horoscope is and how it works, since transits build on everything else.
