The appreciation of daylight goes back practically as far as the history of humankind. The ancients relied on it to tell time, using sundials. Great monuments such as the pyramids in Egypt and Stonehenge in England have significant ties to daylight. The Druids created festivals to celebrate it, such as Summer Solstice.

National Daylight Appreciation Day is observed each year on June 21. This day recognizes summer solstice (the longest day of daylight in the northern hemisphere) and encourages people to celebrate the many benefits of the sun. It's also a day devoted to the many benefits of daylighting, which is a term that refers to the use of natural light to brighten an interior space, as opposed to electric lighting.
