The excecutive summary would state that the clock moves ahead on = mean time whereas the sun, being a jolly fellow, is not in the least = mean. If you examine the analemma you will see that from early Sept. to 20 = Dec. the clock is behind the sun but starting about Nov 1, the clock = begins to gain on the sun and continues to gain until early Feb. [By Dec = 20 the clock is ahead of the sun. ] Because day length, measured by the = clock is of constant length this must mean that sun day length during = this period, when the clock gains on the sun, is less than 24 clock = hours in length.=20 This I think arises from our good fortune in the Northern Hemisphere = that the earth is nearest the sun about Dec 20.

Regards Jamie Sent from Samsung Mobile -------- Original message -------- From: Andy Moir/Christine Callaghan=20 Date:12-23-2014 8:09 AM (GMT-04:00)=20 To: NatureNS=20 Subject: [NatureNS] why aren't the days getting longer=20 According to the environment canada weather page, we actually got 1=20 minute less sunlight today than yesterday. I understand about solar=20 noon (I think), so I'm not really expecting sunrise to be earlier each = day...but the total hours of sunlight should be increasing, not=20 decreasing, after the solstice, I thought. What up with that? Is it=20 perhaps some rounding issue with the Environment Canada calculator? I = get the same result (less sunlight time, when I go to the NOAA solar=20 Calculator) Thanks.
