The Sky This Week, 2013 December 17 – 24 — Naval Oceanography Portal

The winter solstice falls on the 21st at 12:11 pm EST.  This is the moment when the Sun reaches an ecliptic longitude of 270 degrees, which also happens to be the time when it reaches its most southerly declination.  At this moment the Sun stands directly over the Tropic of Capricorn about 500 miles off the west coast of Chile.  The day of the solstice is the shortest for residents of the Northern Hemisphere….The duration of daylight on the solstice will be just 9 hours 26 minutes here in Washington.

[W]hile the solstice is the shortest day of the year, with 9 hours and 47 minutes of daylight in Albuquerque, it is just seconds shorter than days on either side of the solstice.  In fact, the U.S. Observatory lists the length of daylight in Albuquerque (in 2013) as 9 hours and 48 minutes from December 16th through 20th and December 22nd through 26th.

Safe to say Abq is farther south than DC — we get 21 extra minutes of daylight (plus about 200 days more). I wonder if you can calculate just how much farther south using that time difference.
