But not every culture just has four seasons. Evidence is that most cultures just recognise summer and winter, and might add other seasons later, as societies become more complex.
The traditional time reckoning systems of the #Cherokee, #Kiowa, and #Haida only had summer and winter, with long periods of time described as "n winters ago". More recent events were described as "k moons ago", but the cycles of the sun and the moon were tracked seperately, with no attempt at harmonisation.
