The book of hours has its ultimate origin in the Psalter, which monks and nuns were required to recite. By the 12th century this had developed into the breviary, with weekly cycles of psalms, prayers, hymns, antiphons, and readings which changed with the liturgical season. Eventually a selection of texts was produced in much shorter volumes and came to be called a book of hours.

Many books of hours were made for women. There is some evidence that they were sometimes given as a wedding present from a husband to his bride. Frequently they were passed down through the family, as recorded in wills.

Although the most heavily illuminated books of hours were enormously expensive, a small book with little or no illumination was affordable much more widely, and increasingly so during the 15th century. The earliest surviving English example was apparently written for a laywoman living in or near Oxford in about 1240. It is smaller than a modern paperback but heavily illuminated with major initials, but no full-page miniatures. By the 15th century, there are also examples of servants owning their own Books of Hours. In a court case from 1500, a pauper woman is accused of stealing a domestic servant's prayerbook.

Very rarely the books included prayers specifically composed for their owners, but more often the texts are adapted to their tastes or sex, including the inclusion of their names in prayers. Some include images depicting their owners, and some their coats of arms. These, together with the choice of saints commemorated in the calendar and suffrages, are the main clues for the identity of the first owner.

By the 15th century, various stationer's shops mass-produced books of hours in the Netherlands and France. By the end of the 15th century, the advance of printing made books more affordable and much of the emerging middle-class could afford to buy a printed book of hours.
