Umbrella Day takes place on February 10, 2025. The day honors the famous invention to protect against rain or sunlight. An umbrella or parasol is a canopy designed to protect against rain or sunlight. The word parasol usually refers to an item designed to protect from the sun; umbrella refers to a device more suited to protect from rain.
Umbrellas are now a consumer product with a large global market. Umbrellas continue to be actively developed. In the US, so many umbrella-related patents are being filed that the U.S. Patent Office employs four full-time examiners to assess them. As of 2008, the office registered three thousand active patents on umbrella-related inventions. (With material from: Wikipedia)
