As long as I have known, born and raised in America, "the season" begins on the last Thursday in November (Thanksgiving/harvest) Then there is Dec 24th(Christmas Eve) and Dec 25th(Christmas day) and ends on Jan 1st. (New Years Day). There's a break until spring then Easter Day (last Sunday in March) happens.

Thanksgiving (Last thurs. in November which is really just a harvest festival and an excuse to eat to the point of gluttony) , Christmas Day (Dec 25th represents the birth of Christ) and Easter (Represents the resurrection of Christ) are an "important" part of American culture even among "non-Christians"

It's a familiar theme. It's based on death and rebirth of life (or Christ if that's what you believe) as the seasons progress from Autumn equinox, to Winter Solstice, to Spring equinox . To break it down, It's sun worship, in it's most basic form. A theme which has existed in many religions predating Christianity by many thousands of years and for good reason. Annual Life and death cycles on earth are largely influenced by the seasons.

Obviously they had the northern hemisphere in mind when choosing certain calander dates.

Don't sweat it. indeed "Christmas" is a "season" which happens during the shortest days of the year.
