We didn't need the calendar to know the season is changing, based on the cooler weather sweeping in (especially, at night), and having to slosh through fallen leaves, and crunch the squirrels discarded acorn shells, as we walk down the street.
Wikipedia tell us that;
Autumn (also known as Fall in North American English) is one of the four temperate seasons. Autumn marks the transition from summer into winter, usually in late March (southern hemisphere) or late September (northern hemisphere) when the arrival of night becomes noticeably earlier.
n theory, astronomically, the equinoxes ought to be the middle of the respective seasons, but temperature lag (caused by the thermal latency of the ground and sea) means that seasons appear later than dates calculated from a purely astronomical perspective. The actual lag varies with region, so some cultures regard the autumnal equinox as "mid-autumn" whilst others treat it as the start of autumn (as shown in the above table).
Autumn starts on or around 15 September and ends on about 20 December in solar term.
And of course, darkness comes much earlier (not quite as bad as Monty Python had it - ""I had to get up in the morning at ten o'clock at night, half an hour before I went to bed")
