National Earmuff Day

Celebrated on 03/13/2026

Quick Fact

National Earmuff Day is celebrated on March 13th, the birthday of Chester Greenwood, who invented earmuffs in 1873 at the age of 15. Greenwood's patent for the 'Greenwood Champion Ear Protector' was awarded in 1877, and his invention is now a staple for cold-weather comfort worldwide.

Origins and Establishment of National Earmuff Day

National Earmuff Day honors Chester Greenwood, who invented the first earmuffs in 1873 in Farmington, Maine. At just 15 years old, Greenwood grew tired of cold ears while ice skating and fashioned a wire frame with fur pads, held together by a metal band. He patented his design as the "Greenwood Champion Ear Protector" in 1877, and local production began in a small factory. The day was established to commemorate Greenwood's birth on March 13, 1858, and his contribution to winter wear.

Evolution and Modern Commemoration

Initially, Greenwood's earmuffs were handmade and sold locally, but they quickly gained popularity across the United States. Over time, designs evolved from fur and wire to modern materials like foam, plastic, and fleece, and they became mass-produced. Today, National Earmuff Day is celebrated with social media campaigns, educational events in Maine (where Greenwood is a local hero), and promotions by earmuff manufacturers. The day also serves as a reminder of the inventor's ingenuity and the importance of protecting one's hearing in cold climates.
