About First Day of Winter (Northern Hemisphere) 2027
The december solstice of 2027 falls on December 22, 2027 at 02:37 UTC — the astronomical start of winter in the Northern Hemisphere (summer below the equator).
Astronomically, this is the Sun at its southernmost point — winter begins in the north, summer in the south. It is also the day the tide of daylight turns: after the December solstice the change is barely minutes per week, then accelerates — the reason the weeks after a solstice feel darker (or lighter) faster than the solstice day itself.
