February 29th, known as Leap Day, occurs only once every four years, making it a unique and special occurrence. This additional day in the calendar prompts questions about the science and math behind Leap Years and why they exist.
The concept of Leap Years is rooted in the Earth's rotation and orbit around the sun. While it may seem logical for the Earth to spin an even number of times for each orbit, factors such as tidal friction and the moon's influence cause discrepancies. To align the calendar with the Earth's rotations, it was determined that adding an extra day every four years would compensate for the extra time.
