Anyone sick of the dark yet? You don't have to wait too long until every day has more than 12 hours of daylight.

Every day I write down the sunrise and sunset on my forecast sheet which got me thinking how much time have we gained since the Winter Solstice? It turns out that in a little over a month, D.C. has gained 36 minutes of additional daylight. It's also interesting to note that the majority of that daylight was gained in the evening and not in the morning, with only 4 minutes gained in the morning compared to 33 in the evening. While those numbers officially do not add up (haha), they are correct as there are seconds involved as well which were not included. To see for yourself, check out the U.S. Naval Observatory's page on the duration of daylight and darkness for a year and go to "Computer Table".

I included many other random times such as how much additional light we'll have by the end of February (1 hour and 17 minutes more than today). 11 days after that we Spring forward! Just think, the sunrise will once again be after 7a but the sunset will be 7:12p. I imagine my colleague Mr. Doug Hill will be very happy with that little statistic.

The region finally hits 12 hours of daylight by March 17th, 13 hours of daylight by April 9th, and 14 hours of daylight by May 5th. The longest our day gets is 14 hours and 54 minutes long. That's only 5 hours and 28 minutes more daylight than we had a month ago.

What else is nice? We're already behind the climatologically coldest point of the year which ended on the 23rd of January. Looking ahead, our normal high by the end of February is 51 degrees and by the end of March is 61 degrees. For more climate information at Reagan National Airport, visit this page. Now who's ready for sunshine and warmer temperatures!?!
