Key Point: Her personality traits, discipline, and drive were shaped under the influence of 丁火 supporting her Day Master’s ability to overcome challenges. While it's said that 丁火 (Yin Fire) controls 庚金 (Geng Metal), this interpretation can be misleading. In BaZi and Feng Shui, elemental control often signifies a clash, which tends to bring injury or disruption rather than harmony.

Key Point: The 2nd DaYun, 戊子 (1944–1953), and the 3rd DaYun, 己丑 (1954–1963), were the two most favorable luck pillars in Margaret Thatcher’s life. During these periods, the elements and interactions in her BaZi chart supported her personal growth, education, and career foundation. These decades laid the groundwork for her disciplined mindset, strategic thinking, and ambition, which later propelled her rise in politics. The favorable combination of Day Master support and helpful elements during these DaYun allowed her talents and potential to be cultivated effectively, preparing her for the challenges and leadership roles that awaited in later cycles.

This period amplified her natural energy, determination, and assertiveness, fueling her drive to take on challenges and step into leadership roles. Overall, this DaYun was pivotal in shaping her assertive character and preparing her for the high-pressure world of politics that she would soon enter.
5th DaYun: 辛卯 (1974-1983)
- Elemental influence: 辛 Metal strengthening authority, Bing 丙 + Xin 辛combined Water providing challenge
- Focus: Peak political career
- Timeline highlights:
- Served as Prime Minister of the United Kingdom (1979–1990).
Age: 49–58

- Water element enhanced strategic thinking and reflection during political turbulence.
- On October 12, 1984, survived IRA assassination attempt at the Grand Hotel in Brighton.
Age: 59–68
Key Point:
In 1984, during the JiaZi (甲子) year, she entered the 壬辰 (1984–1993) DaYun at age 60. The revealed 壬 (Yang Water) Eating God clashed with the Seven Killings star 丙 (Yang Fire), coinciding with her survival of the IRA assassination attempt.
To say she survived because 壬 controls 丙 is incorrect. In BaZi, a clash—especially between Ten Gods like Eating God and Seven Killings—is inherently disruptive and often dangerous. Control in this context does not imply protection; it signals conflict, and clashes are rarely auspicious.
7th DaYun: 癸巳 (1994-2003)
Age: 69–78
During the age range of 69–78 (i.e., in her 7th DaYun: 癸巳), Margaret Thatcher experienced noticeable declines in health — she suffered a minor stroke in 2002 at around age 76.
These health issues reflect the weakening influences of this DaYun phase, when her body’s resilience started to wane and the challenge of maintaining public activity became more pronounced.
Key Point: 癸巳 DaYun, Gui 癸 combined Wu 戊 and with 巳 Fire, Fire her favorable her status was very strong. But instead of good health and more influences this period did not bring improvements in health. In her mid 70s, she experienced minor strokes and a gradual decline in physical resilience.
8th DaYun: 甲午 (2004-2013)
Age: 79–88
Despite the presence of stronger favorable elements—Fire and Earth—her health continued to decline. In 2013, during the 癸巳 (Gui Si) year, when Fire was especially dominant, she passed away.
Key Point: In the 8th DaYun, 甲午 (2004–2013), the strong Fire element in Margaret Thatcher’s chart continued to dominate, maintaining her symbolic authority and legacy even as her public activities diminished. If Fire remained favorable, it could have prevent the natural decline of physical vitality that accompanies aging. During this period, her health issues became more pronounced: she suffered falls, fractured her arm, and experienced cognitive decline associated with dementia. Ultimately, in April 2013, she passed away from a cerebrovascular event at the age of 87.
