Winter Solstice

I was having a 'discussion' with my boss on what was the meaning of winter solstice. You must be thinking we were such a cultured group to be talking about Chinese traditions. Well, we were more of idle chatting than engaging in some intellectual discussion. He argued that Winter Solstice signified the end of Winter while I speculated that Winter Solstice marked the beginning of Winter. In the end, no conclusion was drawn as both of us were not 100 percent certain of our own guess.

P.S. I did a google and it seemed that Winter Solsticewas not either the end or the beginning of Winter. It was supposed to be mid-Winter. Looked like both my boss and I were wrong in our speculations.
