At least inside, the sun has a definite warmth when it touches you. When I go downstairs every morning to spray the bamboo, bromeliads, and begonias, it's light earlier. Sunrise today was 9:10 am and it sets at 5:18 pm (the moon gets four more hours in the sky) for a total of eight hours eight minutes and 55 seconds. But don't believe everything you read on the internet. The Anchorage Daily News says sunrise today was 9:09 am (five minutes after their scheduled moonrise). And when I went on line to get the ADN link, I found the online version gave yet another time for the sunrise. (Note, the ADN link goes to weather in general and probably changes from day to day.) At least they all agree on sunset time.
I'm not sure how you calculate exact sunrise for a place with mountains to the east.
