We are now in the last month of the year. December, 31 days and Gregorian and Julian Calendars are the twelfth and last months of the year. December had 30 days, until Numa when it had 29 days, until Julius when it became 31 days long. December is the season of winter. Winter is the coldest season of the year in polar and temperate climates (winter does not occur in tropical climates). So the winter season begins on December 1 and ends on February 28 or February 29. At the Winter Solstice (about December 21), the suns rays come straight to the Turn of the Capricorn.
