Answer: June 21
Notes: The General Assembly of the United Nations proclaimed 21 June as the International Day of the Celebration of the Solstice. It aims to celebrate the unity of cultural heritage and traditions, as well as to strengthen ties among people. The seasonal movement of the Sun's daily path appears to stand still at a northern or southern limit before reversing direction. There are two solstices that occur annually namely the Summer Solstice around June 21 and Winter Solstice around December 21.
