Does the solstice mark the start of winter?

So does the solstice mark the beginning of winter? Depends. Yes if we are talking about “astronomical winter”: in this case it is the first day of the winter season. However, if we are referring to “meteorological winter,” then the first day of winter is December 1st.

This is because meteorologists (scientists who study weather and climate patterns) divide the year evenly, with three months for each of the four seasons.

The winter solstice it is not only an astronomical phenomenon, but also a symbol of rebirth and hope in many cultures. For centuries, this date has been celebrated with rituals and holidays that welcome the return of light. Even in Italy, some popular traditions have roots linked to the solstice: for example, the fires lit in many regions of Central and Northern Italy symbolize the light that triumphs over darkness.

Even if there are no particular visible phenomena, the solstice is an opportunity to reflect on the cyclical nature of nature. You can celebrate it by spending time outdoors, perhaps watching the sky at sunset, or by attending events that highlight the importance of the return of light.
