Astronomical vs meteorological winter

This countdown uses astronomical winter, which starts at the solstice. Meteorological winter uses fixed dates and runs from 1 December to 28 or 29 February.

So depending on the definition, winter starts either on 1 December or around 21 December.

Northern and Southern Hemisphere

These dates are for the Northern Hemisphere. Below the equator it is the reverse, which is why an Australian Christmas falls at the height of summer.
