Is that what it's called--the "Solstice"? I've always called it "the bottom of the bloody well" and other worse things.
Where I live (Ireland) it can be a depressing time of year--dark at around 4:30 and not light again until about 9 the next morning. But yes! The days are going to start getting longer now. In only about 3 weeks or so, we'll be able to see the evenings stretching, and that always lifts the heart. You can start looking forward to the days when it's light until at least 11 and then getting light again before 4.
