The Calendar takes the reader on a fascinating journey through the evolution of the calendar, exploring how days, months and years have been codified in a variety of technical and visual forms, from Neolithic stone circles to the sixteenth-century Gregorian Reform and the Revolutionary Calendars of the 20th century.

Celebrating beautiful visualisations, The Calendar is richly illustrated, featuring over 52 calendars, including examples from ancient China and India, Mayan and Aztec cultures, medieval Europe and ancient Japan.

The Calendar is a celebration of the different ways that humanity has measured the year, of how it has squeezed the chaotic dance of heaven and earth into reassuring calm and order. This delightful exploration reveals a meeting of art, science, religion and politics.
