Chidra Dasha Windows

get_chidra_dasha

[Lumin extension] The 'Chidra' window of transition and close-out at the end of every mahadasha, under TWO definitions that both ship: the last 1/8 of the mahadasha by time (with a broader last 1/4), and the mahadasha's own last antardasha read off the dasha tree ('lastAntardasha', 5% to 17% of the mahadasha depending on its lords). Returns each MD's windows, current/past/future flags, and 'definitions'. NEITHER HAS A KP SOURCE: the KP Readers have no dasa chidra, and the fixed 1/8 has no stated locus anywhere, so say which definition you used and never present it as a KP rule. Use to advise pausing major launches as a mahadasha approaches its close.

Parameters

Name	Type	Required	Description
birth_datetime	string	Yes	Birth date and time in ISO 8601 format (e.g., "1990-05-15T14:30:00").
latitude	number	Yes	Birth location latitude. Range: -90 to 90.
longitude	number	Yes	Birth location longitude. Range: -180 to 180.
utc_offset_minutes	number	Yes	UTC offset in minutes (e.g., 330 for IST, -300 for EST).
ayanamsa	enum: kp \| kp_new \| lahiri \| raman \| true_chitra \| khullar	No	Ayanamsa system. Defaults to kp.
query_date	string	No	ISO date to evaluate against (default: now). Send a zone (Z, or +hh:mm as in 2026-10-20T10:30:00+05:30). A value without a zone is read as UTC, never as local time, and a date alone is midnight UTC. This is a different moment from judgement_datetime, which is a local wall clock sent with its own offset.

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.
