I talked about seasonality a bit back in Monochronic time. I never felt particularly attuned to seasons -- time has tended to be a general wash. But the last few years, I've really felt it. Why?
Changing weather conditions. Summers are a lot warmer, beyond the threshold of 'unremarkably tolerable' that they used to be for me. Hotter -- dangerously ever-hotter -- summers throw seasons into sharper relief for me. I long for summer to end, and autumn to arrive.
Birds. The first singing of the chiffchaffs, later the wrens. The arrival (and departure) of the swifts. The change in their behaviour. By our macro seasons, yes, but also by the local 'seasons' or phases of climate and human activity and whatever must pass for the bird calendar.
Self-awareness. I'm a creature of routine and habit. I tend to optimise my time and my space and my routines to let me do all things I want -- or need -- to do. There's an element of smoothness to this time -- both in a positive and negative sense. The smoothness of everything happen as and when it should. And the frictionless horror of something that you can't get purchase on, sliding from one thing to the next. I'm more and more aware, though, the cylical and season nature of my own capacities, interests, and energies. This leads me to reflect more and more on the phasic nature of time, and the benefits of seasonality and variability.
