Overview

National Daylight Appreciation Day coincides with the summer solstice in the Northern Hemisphere each year.

Why it matters: National Daylight Appreciation Day, observed each year on the summer solstice, encourages communities to celebrate the longest day of the year.

Origin and story

The date universally coincides with the summer solstice, marking the longest period of daylight and the shortest night of the year in the Northern Hemisphere.

The word "solstice" originates from Latin, combining "sol" (sun) and "sistere" (to stand still), as the sun appears to pause its northward or southward movement.

Ways to celebrate

National Daylight Appreciation Day was created in 2015 by Solatube International, a daylighting company, but it lands on a date people have marked for millennia: the summer solstice, when the Northern Hemisphere gets its longest stretch of sun all year.

Trace the day back to ancient solstice rites

Long before a company put a name on it, cultures across Greece and Europe welcomed the solstice with bonfires and feasts marking the start of a new growing season and the sun at its peak strength.

Use the extra daylight instead of scheduling around it

Since the summer solstice brings the most daylight of the year in the Northern Hemisphere, put the extra hours to use: an evening walk, a bike ride, or a picnic scheduled for a time you'd normally lose to darkness in December.

Did you know?

The solstice doesn't bring the year's hottest weather — oceans and land take weeks to absorb and release the sun's energy, a lag that pushes peak summer heat into July and August instead.
