I'm from Australia and so right now I am in autumn as everyone in Europe is getting getting ready for spring.
I'm interested in hearing about your seasons and what sorts of events/calendar markings/celestial or weather shifts mark the change of each season for you.
Here we typically denote 4 equal seasons of 3 months each, but in some parts of Australia we have wet/dry seasons and in other parts we note 6 main seasons based on plant an animal life shifts (so not strongly tied to the calendar).
What is it like for you where you are?
