I always thought the solstices and equinoxes were the middle of the season, but that can't be right if January and February are considered to be winter. I wonder why our year starts partway through winter?
I prefer the one about looking at what nature's up to, but one of our little apple trees is starting to change colour whilst our other plants aren't.

An equinox is when the length of daylight is equal to the length of darkness. The Summer solstice is when the daylight time is at it's longest and Winter solstice is when the daylight time is at it's shortest. Taking those things into consideration when using the astronomical calendar the seasons start at a later time than when using the meteorological calender. The meteorological calender divides the 12 months of the year into 4 equal parts thus the seasons are also three months long. Hence the difference. Autumn is a bit of an oddball as it's beginning is not actually fixed in time, nor is it's length 3 months of the year. Autumn starts when the leaves on the trees in your area begin to change colour, and will continue until the leaves have fallen, or Winter solstice occurs in the astronomical calendar. The meteorological calender ignores this and simply divides the year into the four seasons. Confused? Your little apple tree could be telling you that an early frost may be on the cards.
