Agatha Christie’s Hercule Poirot Calendar 2025

For the first time, Hercule Poirot—“probably the greatest detective in the world” —is celebrated in the first official Agatha Christie calendar in the USA, comprising brand-new cover designs from the bestselling books.

Hercule Poirot appeared in Agatha Christie’s very first novel, The Mysterious Affair at Styles, in 1920. More than a century later, the mustachioed Belgian detective finally makes his wall calendar debut in this official 2025 Agatha Christie calendar.

To coincide with brand-new cover designs for the Hercule Poirot series, this calendar is a showcase for some of the most attractive new artworks, featuring some of Agatha Christie’s most evocative titles. Glorious renditions of these stories and more can adorn your favorite wall and help to celebrate the never-ending charm of “the greatest detective in the world.”
