Earth’s Rotation Day is observed annually on January 8 to honour the groundbreaking 1851 experiment by French physicist Léon Foucault, who provided the first conclusive proof of Earth’s rotation using a pendulum at the Panthéon in Paris. The Foucault pendulum demonstrated that the Earth rotates on its axis by showing the gradual rotation of the pendulum’s plane of oscillation. This day highlights the importance of Earth’s rotational motion, which governs the day-night cycle and seasonal changes, and celebrates a milestone in humanity’s scientific understanding of planetary dynamics.
