Vimshottari Dasha Periods
get_dasha_periods
Compute Vimshottari dasha, KP's 120-year planetary period system. Levels: mahadasha (main period, years), antardasha (sub-period, months), pratyantardasha (sub-sub-period, days). Returns '{ mahadashas: [{ planet, startDate, endDate, subPeriods }], currentDasha: { mahadasha, antardasha, pratyantardasha } }'. **Returns mahadasha and antardasha by default. The full pratyantardasha tree for all 120 years does not fit one response, so for PD detail call 'get_pratyantardasha_periods' for the mahadasha you care about — do NOT skip PD, KP's 3-lock rule needs MD, AD and PD to all signify.** Use when: you only need raw dasha periods. For event-relevance scoring, prefer 'get_smart_current_dasha' or 'get_event_dasha'.

}Birth data
This tool requires birth data on every call. The MCP server is stateless, so calling set_birth_profile first validates the data and returns the reading plan, but it does not store anything. Repeat the same five fields here.
