The winter solstice, a pivotal moment in the Earth’s annual cycle, arrives on December 21st, 2023, at 16:03 CET. This marks the shortest day and longest night of the year in the Northern Hemisphere, and the official start of astronomical winter. While meteorological winter began on December 1st,the solstice holds a deeper cultural and astronomical meaning,representing a turning point as days begin to lengthen once more.
Understanding the Solstice: Earth’s Tilt and orbit
The solstices – both winter and summer – occur as of the Earth’s axial tilt of approximately 23.5 degrees. As Earth orbits the Sun, different parts of the planet are tilted more directly towards it. During the winter solstice, the Northern Hemisphere is tilted furthest away from the Sun, resulting in less direct sunlight and shorter days. The Southern Hemisphere experiences the opposite – their summer solstice.
The Earth’s orbit isn’t a perfect circle, but an ellipse. This, combined with the axial tilt, means the exact date and time of the solstice vary slightly each year. It typically falls on December 21st or 22nd, but can occasionally be on December 20th or 23rd.
