NEW DELHI: On December 22, the Northern Hemisphere observes the Winter Solstice, heralding the official commencement of winter and marking the shortest day of the year. This astronomical event, also known as the ‘hiemal solstice’ or ‘hibernal solstice,’ occurs when the Earth’s axial tilt reaches its maximum at 23.5 degrees away from the sun. At precisely 4:44 pm GMT, the solstice unfolds, signifying the sun’s lowest point in the sky during the year.
The anticipated schedule for the shortest day includes a sunrise at 7:10 am and a sunset at 5:29 pm. The solstice’s occurrence is rooted in the Earth’s axial tilt, causing either the northern or southern hemisphere to be tilted away from the sun. This tilt results in two solstices annually, one in summer and the other in winter.
The term “solstice” originates from the Latin words ‘sol,’ meaning sun, and ‘sister,’ signifying “to come to a stop or make stand.” December’s winter solstice, therefore, symbolises the “astronomical” onset of winter in the northern half of the globe.
Following the winter solstice, daylight hours in the Northern Hemisphere will gradually lengthen, leading up to the summer solstice, which marks the longest day of the year. This celestial phenomenon typically occurs between June 20 and 22, signifying the moment when the northern half of the Earth is tilted closest to the sun.
