Mahadashas are the long planetary periods that frame your life into chapters. The Vimshottari system runs 120 years across nine periods (Sun through Ketu) and Tempora uses it as the primary timing engine. Each of the eight articles below is the deep dive for one period: how long it runs, which sub-periods mark the turning points, how the experience shifts by ascendant and what the closing window typically asks of the person living it. Read this cluster when a new mahadasha is beginning in your chart or when you want to understand what the current chapter of your life is structurally about.
