Slowly but surely the sun is rising later and setting earlier.
It's that time of year when you notice the sun rising later and later, and before you know it, you'll need your headlights on at 6pm. Here's a brief breakdown of the amount of daylight in Washington and how much it's changing.
Today in Washington there is 12hr 4min of daylight, but we lose 1hr and 14min over the next 30 days alone. Basically, we add two and a half minutes of darkness every day between now and October 24th. Thursday (the 26th) will be the first time D.C. has had under 12 hours of daylight since March 16th. See the chart here.
Our daylight hits rock bottom around the winter solstice with only 9hr 26min of daylight then. It may feel dark that time of year, but it's nothing like Anchorage, Alaska where they have an annual low of only 5hr 28min of daylight.
