Originally published in 1926, this book contains a general history of the measurement of time now known as the week. Colson begins with the seven-day cycle devised by the Jews and examines how different theologies gave rise to different names and systems of measurement for each day of the week and how the week eventually became standardised. This book will be of value to anyone with an interest in ancient astronomy and the history of time keeping.
