For the Northern hemisphere's winter, the Tropic of Capricorn.
For the Southern Hemisphere's winter, the Tropic of Cancer.
December 21/22 is the official first day of winter
The first day of spring is an equinox, as is the first day of autumn. Solstices occur on the first day of winter and the first day of summer.
First day of Summer is in June, first day of Winter is in November.
The winter solstice, which usually occurs around December 21.
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.
For spring the tropic of Cancer, for fall the tropic of Capricorn (i think, because I'm pretty sure that summer it's over the equator, but I'm a little fuzzy as to where it is in the winter. but I'm still pretty sure the equinox's are over the tropics.)
The first day of winter is never in November.
Northern-hemisphere Winter begins when the sun reaches its farthest positionsouth, on or about December 22, appearing overhead on the Tropic of Capricornat about 231/2°south latitude.Southern-hemisphere Winter begins when the sun reaches its farthest positionnorth, on or about June 21, appearing overhead on the Tropic of Cancer at about231/2° north latitude.

the winter solsctice
December. The first day of winter is the solstice, usually around the 21st of the month.
If the axis on which the Earth is spinning. one revolution per day, were perfectly vertical there would be no seasons. The sun would be over the Equator at all times night and day, summer and winter. However the Earth's axis is tilted. This means that during one year, as the Earth goes round the Sun, the Sun is only over the Equator on two days a year. The rest of the time it is either moving north to the Tropic of Cancer and back or south to the Tropic of Capricorn and back. So someone in England or USA would have the smallest,shortest shadow on the day the Sun was above the Tropic of Cancer (Midsummer Day) and the longest when the Sun was over the Tropic of Capricorn (Midwinter Day). The opposite would apply for an Australian.
Summer. The first day of summer is the longest day of the year. The first day of winter is the shortest day of the year.
