The first day of winter is the correct technical term. The winter solstice is a single moment each year that occurs between December 21 and 23 in the northern hemisphere. It is the moment when a pole is furthest from the sun. The hours of daylight change from getting shorter to getting longer. The day on which this happens is the first day of winter. Because it is difficult to determine the moment of solstice, by observation, to a precision of less than a day; the first day of winter is often referred to as the winter solstice. The first day of winter in the southern hemisphere lies between June 20 and 23 when the northern hemisphere is experiencing the summer solstice.
Because it marks the first day of the New Year on the Gregorian calendar, just as the Fourth of July is on the Fourth of July in the US and the Winter Solstice is celebrated on the day of the Winter Solstice, December 21.
