Sade Sati Phases (Saturn 7.5-yr Cycle)

get_sade_sati_phases

Saturn's 7.5-year transit through 12th, 1st, and 2nd signs from the natal Moon, decomposed into the three named phases (Vraya / Janma / Patha) per cycle. Returns each cycle (past + current + future) with absolute start/end dates, current-phase status, days remaining, and auxiliary windows for Ashtama Shani (Saturn in 8th from Moon) and Ardha-ashtama (Saturn in 4th from Moon). **The phase name is NOT the verdict.** KP Reader 5 defines the period at canon p.296 and then rejects the traditional reading of it, noting that people marry, get promoted and buy property during Sade Sati: "At the time when they predict adverse results, we enjoy pleasure" (p.297). The KP verdict is chart-dependent and comes from 'starLordWindows', one per nakshatra Saturn crosses inside each phase, each judged on that star lord's house lordship in THIS chart: signifying 8 or 12 is adverse (p.298), 10 or 11 benefic (p.297). 'currentStatus.currentStarLord' gives the live verdict. The traditional adverse reading is retained per phase under 'traditionalReading', tagged 'vedic-parashari' and disclaimed; report it as the traditional view if you use it, never as the KP one. A verdict of UNKNOWN means significators were unavailable, so say there is no KP verdict rather than falling back on the phase name. Books: KP Reader 5 canon pp.296-299, KP Reader 3 ch.51.

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.
