The winter solstice is the day with the least amount of light (for those of us in the Northern Hemisphere). This means that after the winter solstice, the days gradually begin to lengthen. This is a good thing. By now I've heard the mild complaints about how cold and dark it's been getting. One part of me wants to join in: yes, I hate that it's getting colder. Yes, I hate that it gets dark at 4PM. But more often than not, when I hear these complaints in the hallways, I usually put on a stoic face. Winter's coldness and darkness can only be endured. If you choose not to escape it, you have to accept it. Commiserating doesn't make it warmer or lighter.
The other name for the winter solstice is "midwinter". I like that too. The days are lengthening, and even though New England will remain "cold" for at least another few months, we're past the half-way point. The Earth will gradually tip its northern axis towards the sun again, and before you know it, we'll be mildly complaining about all the heat.
