The microwave oven was accidentally invented in 1945 when Percy Spencer, a Raytheon engineer, noticed a candy bar melted in his pocket while testing a magnetron. The first microwave oven sold commercially, the 'Radarange,' was nearly 6 feet tall, weighed 750 pounds, and cost $5,000 in 1946. National Microwave Oven Day is celebrated on December 6th each year, honoring this kitchen staple that over 90% of American households now own.
National Microwave Oven Day is observed annually on December 6th. The exact origin of the holiday is unclear, but it is believed to have been created by food enthusiasts and appliance manufacturers to celebrate the convenience and innovation of the microwave oven. The date may coincide with the anniversary of Percy Spencer's invention, as his patent for the microwave oven was filed in 1945. The holiday gained popularity through social media and food blogs, encouraging people to appreciate their microwaves by cooking a special meal or trying new recipes.
Initially, microwave ovens were large, expensive, and primarily used in commercial settings like restaurants and ships. By the 1970s, countertop models became affordable and widespread, revolutionizing home cooking. Today, National Microwave Oven Day is celebrated with online campaigns, microwave-friendly recipe sharing, and even microwave cooking competitions. Many brands and influencers use the day to highlight the versatility of microwaves, from reheating leftovers to baking cakes and making popcorn.
