When does winter occur in the northern hemisphere?
The winter solstice occurs during the hemisphere's winter. In the Northern Hemisphere, this is the December solstice (usually 21 or 22 December) and in the Southern Hemisphere, this is the June solstice (usually 20 or 21 June). Although the winter solstice itself lasts only a moment, the term sometimes refers to the day on which it occurs. Other names are "midwinter", the "extreme of winter" (Dongzhi), or the "shortest day". Traditionally, in many temperate regions, the winter solstice is seen as the middle of winter, but today in some countries and calendars, it is seen as the beginning of winter. In meteorology, winter is reckoned as beginning about three weeks before the winter solstice.

In the Northern Hemisphere, some authorities define the period of winter based on astronomical fixed points (i.e. based solely on the position of the Earth in its orbit around the Sun), regardless of weather conditions. In one version of this definition, winter begins at the winter solstice and ends at the March equinox

Winter
As often defined by meteorologists, winter occurs in the three calendar months with the lowest average temperatures. This corresponds to the months of December, January and February in the Northern Hemisphere. However, in the Northern Hemisphere, some authorities define the period of winter based on astronomical fixed points, or points based solely on the position of the Earth in its orbit around the Sun, regardless of weather conditions. In one version of this definition, winter begins at the Winter Solstice, which usually occurs around December 21st, and ends at the March Equinox, which usually occurs around March 20th. Therefore, based on this definition, the winter season in the Northern Hemisphere would be from approximately December 21 - March 20.
