Calendar seasons are mainly used to talk about the weather. Using Equinox as a fixed reference point is not any more precise than using meteorological conventio

  Here is what Equinox means and how it's related to weather in general https://www.weather.gov/lmk/seasons https://www.weather.gov/lmk/seasons > Using Equinox as a fixed reference point and a is not any more precise than using meteorological convention wrt thermal seasons Well, no. What meteorological convention? That's a pretty broad term. We are talking about calendars, not a general weather forecast system, as I was comparing Persian calendar with other calendars. With Equinox, you get a good indication of weather conditions for a wide geography while having a precise reference point to design a calendar which can be used for other equally important purposes. P.S. While I was thinking about what you wrote, I wondered how these things were argued and arranged in ancient times and what did they think or say considering what they had to come up with affects a significant portion of the civilized world and trade between nations.
