Winter solstice occurs on December 21 or 22, when the night hours are the longest.<\/li>\n<\/ul>\n<p><strong>But why are the hours of daylight not the same every day?<\/strong><\/p>\n<ul>\n<li style=\"text-align: justify;\">The explanation lies in Earth\u2019s tilt. The planet\u2019s axis of rotation is tilted at an angle of 23.5\u00b0C. This tilt \u2014 combined with factors such as Earth\u2019s spin and orbit \u2014 leads to variations in the duration of sunlight on any location on different days of the year. The tilt is also responsible for the different seasons.<\/li>\n<\/ul>\n<p><strong>Day &amp; night<\/strong><\/p>\n<ul>\n<li>Day occurs on the side facing the Sun, and changes to night as Earth continues to spin on its axis. On the Equator, day and night are equal. The closer one moves towards the poles, the more extreme the variation. During summer in either hemisphere, that pole is tilted towards the sun and the polar region receives 24 hours of daylight for months. During winter, the region is in total darkness for months.<\/li>\n<\/ul>\n<p><a href=\"https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2018\/06\/graph-2.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1340\" src=\"https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2018\/06\/graph-2.jpg\" alt=\"\" width=\"759\" height=\"404\" srcset=\"https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2018\/06\/graph-2.jpg 759w, https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2018\/06\/graph-2-150x80.jpg 150w, https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2018\/06\/graph-2-300x160.jpg 300w\" sizes=\"auto, (max-width: 759px) 100vw, 759px\" \/><\/a><\/p>\n<p><strong>Key latitudes<\/strong><\/p>\n<ul>\n<li style=\"text-align: justify;\">A latitude is a measure of a location\u2019s distance from the Equator.

At latitudes of 23.5\u00b0 (matching the tilt) are the Tropics of Cancer and Capricorn, north and south of the Equator. At 66.5\u00b0 (or 90\u00b0 minus 23.5\u00b0) are the Arctic and Antarctic Circles, north and south. It is at latitudes higher than 66.5\u00b0 (in either direction) that days of constant darkness or light occur<\/li>\n<\/ul>\n<p><a href=\"https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2018\/06\/graph-31.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-full wp-image-1341\" src=\"https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2018\/06\/graph-31.jpg\" alt=\"\" width=\"759\" height=\"430\" srcset=\"https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2018\/06\/graph-31.jpg 759w, https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2018\/06\/graph-31-150x85.jpg 150w, https:\/\/triumphias.com\/blog\/wp-content\/uploads\/2018\/06\/graph-31-300x170.jpg 300w\" sizes=\"auto, (max-width: 759px) 100vw, 759px\" \/><\/a><\/p>\n<p><strong>Solstice<\/strong><\/p>\n<ul>\n<li style=\"text-align: justify;\">On each Tropic, the sun is directly overhead at noon once a year.
