Antardasha is a sub-period within a Mahadasha, lasting months to years, that modifies the major period with a secondary planetary influence.
Each Mahadasha is divided into nine Antardashas, one for each planet. The Antardasha adds nuance to the Mahadasha—for example, Jupiter Antardasha within Saturn Mahadasha might bring opportunities for growth within an otherwise restrictive period. Understanding both levels helps make sense of life's variations within longer themes. Further divisions (Pratyantardasha, etc.) offer even finer timing.
TriAstra tracks your Antardasha periods and shows how they interact with your Mahadasha, creating a detailed timeline of planetary influences throughout your life.
Knowing your current Antardasha explains why different months or years within the same Mahadasha can feel so different—the sub-period modifies the overall planetary theme.
Understanding Antardasha (Sub-Period) is just the beginning. See how it manifests in your unique birth chart with TriAstra's triple-system analysis.
