On 1 January 1660 ("1 January 1659/1660" in contemporary terms), Pepys began to keep a diary. He recorded his daily life for almost ten years. This record of a decade of Pepys's life is more than a million words long and is often regarded as Britain's most celebrated diary. Pepys has been called the greatest diarist of all time due to his frankness in writing concerning his own weaknesses and the accuracy with which he records events of daily British life and major events in the 17th century. Pepys wrote about the contemporary court and theatre (including his amorous affairs with the actresses), his household, and major political and social occurrences.
