National Daylight Appreciation Day – June 21, 2024

On National Daylight Appreciation Day, June 21, we get to enjoy the longest period of sunlight that we will experience in the entire year. It is also the day of the summer solstice, and there will be no other day with as much sunlight as this one — although this does not apply to the extreme northern and southern portions of the planet. On June 21 every year, the sun spends the longest time in the sky and provides us with long hours of sunlight and warmth. National Daylight Appreciation Day celebrates this annual celestial event.

History of National Daylight Appreciation Day

It is no secret that time and dates are man-made phenomena. They were brought into existence for mankind to be aware of the ever-changing atmospheric patterns witnessed through the course of a year. Before we had great technological advancements, humans assumed that there were religious and supernatural elements that determined changes in the cosmos. For example, the summer solstice was understood as a day that marked the transition of the sun god from the land of the living to the land of the dead, to ultimately be reborn in deep winter when the days began getting longer again. In most cultures, the day would be observed with a great ceremony around both these events, to commemorate the sun god’s strength and the anticipation of him being reborn again.

The day of the summer solstice was celebrated with great feasts and new harvests that thrived in the summer sun. We have made significant progress since then and today we understand that the summer solstice is part of the natural movement of our planet. We experience the longest day of sunlight hours as a result of the rotation of the Earth, its orbit around the sun, and the way it is angled on its axial tilt. Thus, National Daylight Appreciation Day reminds us all to go out in the sun and enjoy our time outdoors before the days start to shorten again.
