According to the old Japanese calendar, this year, November 7, is the first day of winter. The year is divided into 24 solar terms, with each term having a name. This year, November 7 through 21 is considered the beginning of winter. The next solar term from November 22 through December 6, Light Snow, is the period when snow starts falling.
For marking the season, I like the old Japanese calendar. Using the equinoxes and solstices makes the beginning of the seasons to late. The winter solstice falls on December 21 this year. By then, it seems winter has been with us for sometime. It makes more sense to use the equinoxes and solstices as the middle of the seasons, not the beginning.
It’s a beautiful start to winter here. After a furious wind and rain storm yesterday, the day started out clear and cool. A perfect way to begin winter.
