On two specific days of the year, June 21 and December 21, if you look up at the sky, you will notice that the sun seems to stand still at its northernmost or southernmost limit before completing its daily path and reversing direction. This impression of a stationary sun led to the event being named the "solstice," derived from the Latin words 'sol' and 'sistere', meaning to stand still. It occurs when the sun reaches its northernmost or southernmost diurnal arc relative to the Equator; thus, two solstices occur annually, marking the beginning of winter and summer in the respective hemispheres.
Historically, this moment has held immense significance for various cultures, marking holidays, rituals, festivals, and ceremonies that, in turn, are tied to religion, agriculture, and fertility. Recognizing the importance of these rituals for cultural heritage and ancient traditions, the UN established June 21 as the International Day of the Celebration of the Solstice to foster mutual respect between different cultures.
