Earth’s Rotation Day is an annual occurrence celebrated on January 8th of every year. All of us are very well aware that the earth rotates. The planet will take 24 hours to complete one full rotation, and due to the rotation, we tend to see the day and night alternatively. Being the only planet on which humans survive, Earth rotates about its own axis. The day is observed to celebrate the French Physicist Leon Foucault, who, in 1851, demonstrated that the Earth rotates on its axis.

“We can’t feel the rotation of the planet, but in some ways we can because our bodily systems are reacting to it and have it inherent in them. To me, that’s such a powerful thought.” – Jessa Gamble

History of Earth’s Rotation Day

The history, origin, founder, and year since the Earth’s Rotation Day have been celebrated are anonymous. However, this observance Day is created to honor the demonstration of Leon Foucault of France. He was the one who mentioned that the earth rotated on its axis in 1851. Foucault suspended a lead-filled brass sphere from the top of the Panthéon in Paris to prove his theory. The lead-filled brass sphere is now called the Foucault Pendulum from the top of the Pantheon in Paris. Foucault’s Pendulum has shown that the plane of the swing of the pendulum rotated relative to that of the Earth’s own rotation. Foucault’s pendulum has demonstrated that the earth’s rotation is the cause of gravity.

How to Celebrate the Day

Get to know more about the earth’s rotation and research its history, as not every day is this celebration Day. You can even enter a museum to see what Foucault’s Pendulum is and what it looks like. Make your kids learn about this concept with a working model. Take them to learn about Earth’s rotation by visiting a local space and science museum. Share your views and celebration photos about this day on social media using the hashtag #EarthsRotationDay.
