Look at this chart of sunrise and sunset times in Toronto in December 2010.
The solstice is December 21, with 8h 55m 34s of daylight. Sunrise is at 7:48 AM and sunset is at 4:43 PM.
But then sunrise time keeps getting later. It's 7:49 on December 23, 7:50 on December 25, and 7:51 on December 29. In fact, it takes until January 17 for sunrise time to get back to being earlier than it was on the solstice.
And I just noticed the same goes for the sunset. It's 4:43 on the solstice, but it's earlier than that on the days leading up to the solstice, going as early as 4:40 between December 7 and 11.
Why is this?
