Methodology and astrological context for Antar Char Dasha.
The Antar Char Dasha API calculates the sub-period (Antar Dasha) breakdown within a specified Major Char Dasha sign period, using Jaimini's sign-based dasha system. It represents the second level of the Char Dasha hierarchy, providing finer time divisions within a major dasha for more granular predictive analysis.
This endpoint drills into a specific major dasha period — identified by the majorSignKey path parameter (e.g., aries, taurus, cancer) — and computes all the Antar Dasha (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 sub-period sign within the chosen major dasha, enabling precise mid-range predictions within the broader major dasha theme.
This endpoint is intended to be used in conjunction with the Major Char Dasha endpoint: the major dasha sign is first identified, then passed to this endpoint to retrieve its internal sub-period structure.
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 Antar Char Dasha breakdown for the specified major sign period, which may include:
