So? I remember watching weather reporters as a kid, and even teachers telling us about seasons in primary school, they always had a clear differentiation between &quot;meteorological seasons&quot; and &quot;calendar seasons&quot;. Meteorological winter started on December 1st, and ended with the first blooming flowers in early March. November is a bit more confusing, because you traditionally start wearing a winter coat on November 1st, but only in the morning as days are still warm-ish.<p>I assume different countries will have different meteorological seasons. Just like most countries within a timezone don&#x27;t exactly sync up with the idea that the sun is at the highest point at noon.
