First Day of Autumn
In Australia we regard Autumn (and all other seasons) starting on the 1st of the month (today). In the Northern Hemisphere the public statements of change in seasons is on the equinoxs (when day equals night- 20th March this year) and longest/shortest days (soltice) or closest public holiday.
Does this have demographic implications? Probably not, although it points to global discontinuities in data which may have subtle explanations. For example, it may be interesting to study the distribution of marriage dates over a year for seasonal bride preferences in different hemispheres.
