I have tried to describe the influence of each day of the year in order to determine the vibrational influence each day has. It lends itself to a philosophical difference where a person born on one day has a slight varying difference to one born on the next day. This is a combination of numerological differences in sequence of slight changes in seasonal developments. I have also tried to determine the different influences of each year & how certain people born in a given year have similar qualities & destined achievements. I have also tried to describe the progression of social change through the years & decades. The centuries have been described in a kind of evolutionary progress or failure starting with the year 1100. The astrological signs have been described in brief form with pertinent facts for each sign. This book also has touched on prophecies for the 21st century. The book is concluded with human interest stories that happen to everyone on a day to day basis. Under each day is listed a famous person with two extra blank lines for the person to put a birthday of someone they know. This, however, is more than just a birthday book. It is a research of different vibrational influences of each day & each given year.Welsch, Harold is the author of 'Day of Your Birth', published 1990 under ISBN 9780962627309 and ISBN 0962627305.
