When does winter start?

Question

When does winter start?

Answer 1

Shamelessly cribbed from wikipedia:

"It is often said that, astronomically, winter starts with the winter solstice and ends with the vernal equinox. In meteorology, it is by convention counted instead as the whole months of June, July and August in the Southern Hemisphere and December, January and February in the Northern Hemisphere. While in actuality, the most accurate start and end point is simply defined by when the first major wave of cold fronts and warm fronts hit a particular area, having no universally predetermined dates."

Answer 2

Dec. 21st. It's the shortest day of the year. I can't tell you about the weather.

Answer 3

For gardeners, winter starts much earlier than the calendar says. For me it is winter in the garden when we start getting regular frosts, all my perennials die back, and I don't need to mow any more. This normally happens in mid-late November here is SE Pennsylvania. .
