Michelle Buchanan, born Michelle Tracey Wilson on March 28, 1969, is a Western Pythagorean numerologist based in Auckland, New Zealand, who has practiced and taught numerology for more than three decades. She became the numerology and spiritual counselor for New Zealand's Woman's Day magazine in 2009 and has served as the resident numerologist on Television New Zealand's long running Good Morning program since 2010, bringing numerology to a mainstream daytime television audience rather than a specialist spiritual one.
In 2012 she launched a numerology program, Discover Your Destiny, on Hay House Radio, and in January 2013 signed an international publishing contract with Hay House for her first book, The Numerology Guidebook, released alongside a companion deck, Numerology Guidance Cards, in December of that year. A second book, Hay House Basics: Numerology, followed in 2015 with an accompanying online course. She has also written as a contributing columnist for the wellness site MindBodyGreen.
Numerology itself, the practice of assigning meaning to numbers derived from names and birth dates, has no basis in mathematics or science beyond the arithmetic used to calculate the numbers, and Buchanan presents it consistently as a self development and reflection tool delivered through mainstream New Zealand media rather than as an empirically demonstrated system. Outside her numerology work she is also a singer and songwriter and the mother of two, and continues to live in Auckland.
