To find out what house your Jupiter is in, you need to look at your birth chart. Jupiters position by house in the natal chart reveals where you express your generosity and tolerance, where you focus on improving your life, and in whom or in what you trust. You can use various online tools to calculate your Jupiter sign and house, such as the Jupiter Sign Calculator on Astrology Library, the What's My Jupiter Sign? tool on Cafe Astrology, or the Jupiter Sign Calculator on BirthChart.net. Once you have determined your Jupiter sign and house, you can refer to the interpretations on Cafe Astrology's Jupiter in the Houses page to learn more about what it means.
