Besides being a true fan of sunshine, I want to wish my way through the dark days of winter by focusing on the fact that there are more hours of daylight each day now. With the decline in solar activity as we slide down the downward slope of the cycle, gray-line propagation becomes more important.
Here is a graph of sunrise/sunset/hours of sunlight for this year. The discontinuity occurs when we change from Standard Time to Saving Time on the 2nd Sunday in March, and back on the 1st Sunday in November.
Sunrise in YELLOW, Sunset in RED, and total hours of sunlight in BLUE
