From the author of No Maori Allowed comes a book that can be used as a trusted source of information on the Māori Lunar Calendar from the perspective of mainstream science. For millennia, Māori and their Polynesian ancestors have used the phases of the moon to guide hunting, fishing, planting, and harvesting – even health and behaviour. But what is fact and what is folklore? The Science of the Māori Lunar Calendar offers an uncensored glimpse into the history of the Maramataka and separates fact from fiction.Does lunar gravity pull on water inside our brains that can lead to dramatic changes in behaviour? Is it true that certain lunar phases can generate ‘high’ and ‘low energy’ levels? Can a full moon lead to more crime and mental health crises?What evidence is there that good and bad fishing days align with the phases of the moon? Is there a link between the moon and menstruation? Why have New Zealand institutions censored information on the Māori Lunar Calendar? Can the Calendar be used to predict the weather? Are certain days better for planting and harvesting? Should Mātauranga Māori be given an equal standing with modern science?Robert Bartholomew holds a PhD in medical sociology and is an Honorary Senior Lecturer with the Department of Psychological Medicine at The University of Auckland.He was inspired to write this book as a source of reliable information for students, teachers, and parents.
