Cornelsen Kalender 2025/2026

The Cornelsen Kalender is a professional academic planner specifically designed for educators and students, produced by the renowned German educational publisher Cornelsen. These planners are typically manufactured within Germany to maintain high quality standards for the domestic educational market. Founded in Berlin in 1946 by Franz Cornelsen, the brand has remained a cornerstone of the German school system for decades.

Today, the brand is part of the Cornelsen Gruppe (Cornelsen Group), which remains under the ownership of the Cornelsen family through the Franz Cornelsen Foundation. This ownership structure ensures the publisher maintains its long-term focus on educational development and pedagogical innovation without the pressures of external corporate shareholders.
