Sunrise, Sunset, Axis Inclination and Orbit: 

My question: For Ottawa Canada, why is the sunrise earlier for December (7:23 AM) than November (7:
42 AM).  Shouldn’t the days start becoming longer AFTER the mid-winter solstice? 

For my location, Ottawa Ontario, Canada, the times listed on the Internet for sunrise for this year are:

January 7:43 AM
February 7:25
March 6:41
April 5:43
May 5:51
June 5:19 
July 5:19
August 5:47
September 6:24
October 7:01
November 7:42
December 7:23

Here are the web site addresses for November and December: 


Thanks in advance for your reply.
