Methodology and astrological context for Pratyantar Char Dasha.
The Pratyantar Char Dasha API calculates the third-level sub-period (Pratyantar Dasha) breakdown within a specified Major and Antar Char Dasha combination, using Jaimini's sign-based dasha system. It represents the third tier of the Char Dasha hierarchy, providing highly granular time divisions for precise short-range predictive analysis.
This endpoint drills into a specific Antar Dasha sub-period — identified by both the majorSignKey and antarSignKey path parameters — and computes all the Pratyantar Dasha (sub-sub-period) sign sequences that fall within it for a given person. Based on the person's birth details, it calculates the start date, end date, and duration of each Pratyantar sign period within the chosen major and antar dasha combination, enabling fine-grained timing predictions for events and transitions at a monthly or weekly resolution.
This endpoint is the third step in a sequential Char Dasha drill-down workflow: the major dasha sign is identified first, the Antar Dasha sub-period is selected next, and then this endpoint is called to retrieve the Pratyantar breakdown within that specific combination.
The Ayanamsha system is configurable via the X-Ayanamsha header, and multi-language support is available through the Accept-Language header.
The response provides a detailed Pratyantar Char Dasha breakdown for the specified major and antar sign combination, which may include:
X-Ayanamsha header for tradition-specific zodiac calculationsAccept-Language header for localized applicationsPayload specifications for JSON request body.
