Chambers Book of Days (The Book of Days: A Miscellany of Popular Antiquities in Connection with the Calendar, Including Anecdote, Biography, & History, Curiosities of Literature and Oddities of Human Life and Character)[1] was written by the Scottish author Robert Chambers and first published in 1864.

[3] The book was published in two large volumes, each over 840 pages long, and, for its day, was well-illustrated with engraved drawings linked to the articles.

Its full title is The Book of Days: A Miscellany of Popular Antiquities in Connection with the Calendar: Including Anecdote, Biography, & History, Curiosities and Literature, and Oddities of Human Life and Character.

... At the same time, the style of Chambers Book of Days (1864) has been preserved by the inclusion of numerous passage from the original volumes, and the selection of these was one of the current author's more pleasurable tasks.

It is hard to surpass Robert Chambers' lyrical descriptions of the characteristics of the changing seasons, for example, extracts of which are included at the beginning of each month.
