National Daylight Appreciation Day

National Daylight Appreciation Day is a holiday that celebrates the longest day of daylight in the Northern Hemisphere. This is the day of the Summer Solstice, and it’s a day when people can enjoy all the hours of sunlight they will receive.

If that doesn’t float a person’s proverbial boat, then they can also use the day to appreciate the windows and skylights of their home that allow all that beautiful sunshine to come in. This holiday falls on June 21st and is a day on which many people will want to take the time to celebrate.

The History of National Daylight Appreciation Day

A term that some people might not be familiar with is “daylighting.” This word describes an indoor location that has windows and skylights allowing daylight into the home.

What does that have to do with the history of National Daylight Appreciation Day? It has a lot to do with it, actually, because this holiday was invented by Solatube International—a company that manufactures daylight devices. Unfortunately, we’re not sure at this moment what year this holiday was created.
