def death_chart_calculator(natal_data): # Calculate houses (using Swiss Ephemeris or PyEphem) houses = calculate_placidus(natal_data) # 8th house cusp and ruler eighth_cusp = houses[8] ruler_sign = get_ruler_of_sign(eighth_cusp) ruler_planet_pos = get_planet_pos(ruler_sign, natal_data)

This is the most dynamic part of predictive work. Astrologers use a "calculator" (ephemeris or software) to progress your natal chart forward, day-for-a-year. Hard aspects (squares, oppositions) from progressed planets or transiting Saturn, Pluto, and Mars to your 8th house, Part of Death, or natal rulers of the 8th can coincide with major health crises or brushes with mortality.

: Specialized calculations like the Part of Death (Ascendant + 8th House Cusp - Moon) are often included for more granular detail.

The calculator looks for "critical degrees" and heavy aspects. For example, if transiting Saturn was exactly conjunct a person's natal Sun at the time of their passing, an astrologer might interpret this as the physical body reaching its natural limit under the weight of time. The Ethics of Predicting Longevity

A death chart calculator will compute this point and show you which zodiac sign and house it falls in. This reveals the manner or theme surrounding the end of life, not the date.
