You're probably noticing the later sunrises and earlier sunsets.  Find out just how much daylight we'll lose by December. 

It's that time of year when it feels dark more than it does light outside.  And yes, that's exactly the case.  Maybe you notice it in the morning before work or school.  Or maybe it's in the evening, when you're unwinding from the day and eating dinner, that you notice it's already dark.  It happens every year, but somehow I'm never quite ready for it. 

After the autumnal equinox back in September, the hours of daylight have been decreasing.  In fact, since September 22st, daylight has decreased by a little over an hour.  By Halloween, we'll have 36 minutes less daylight than we do this week (Oct. 16th).

Hours of Daylight in D.C.

Our shortest length of daylight will occur on December 21st with 9 hours and 26 minutes of daylight.  After the solstice, the hours of daylight will gradually increase.  Then we're back to equal hours of daylight and darkness by the vernal equinox

Even though it may be a little hard adjusting to the shorter daylight hours, we do gain an hour of sleep on November 4th when we switch from Daylight Saving Time to Eastern Standard Time.  The shorter daylight hours also bring the return of cool temperatures and those brilliant leaves through autumn.
