♃ Jupiter in Aries
Jupiter is not in Aries at the moment. It next enters on 21 April 2034 and stays until 29 April 2035.
Every window, computed
Jupiter does not always pass through Aries in one go. When it turns retrograde near the boundary it backs out into the previous sign and returns months later, which splits a single visit into separate windows. Most almanacs quote one date range and lose that.
What this transit concerns
Jupiter governs growth, excess and where things are allowed to expand. In Aries — a fire sign of cardinal tempo — that plays out through fire means: Bold, ambitious, and pioneering, Aries leads with fiery enthusiasm and courage.
Where it lands for you personally depends on which house of your own chart Aries occupies, which is a different question from the one this page answers. Cast your chart to find that.
