We are certainly seeing a change in weather here in Eastern Madera County, California. As I ride my horse in the foothills of Coarsegold, the days are getting shorter and the nights are cooling down.  I was told we are coming into autumn.  I thought we were going into the fall but was corrected that the proper term is autumn.  My research showed that autumn, also known as fall in North American English is one of the four temperate seasons. Autumn is the period between summer and winter, usually in September (northern hemisphere) or March (southern hemisphere) when the arrival of night becomes noticeably earlier. In the northern hemisphere, the meteorological start of autumn is on 1 September and it ends on 30 November. In the southern hemisphere it starts on 1 March and ends on 31 May. The astronomical start of Autumn is on 23 September and ends on 20 December in the northern hemisphere, and 20 March and 21 June in the southern hemisphere. In Ireland, autumn begins on 1 August and ends 31 October, due to the Irish calendar.As for me, fall is easier to spell and it will be fall until I see snow and cold.
