• On 21 st June, the Northern Hemisphere is tilted towards the sun. Since a large portion of the Northern Hemisphere is getting light from the sun, it is summer in the regions north of the equator. At this time in the Southern Hemisphere, all these conditions are reversed. It is winter season there. This position of the earth is called the Summer Solstice.
• On June 21, the Tropic of Cancer experiences the longest day of the year (summer solstice in the Northern Hemisphere), with more than 12 hours of sunlight.
• The Arctic Circle also experiences continuous daylight (midnight sun) on this date, resulting in more than 12 hours of sunlight.
• The Equator experiences approximately 12 hours of daylight year-round, and the Tropic of Capricorn experiences shorter days on this date.
