“a gain of 1 hour of daylight by month’s end”

Roughly 2 minutes a day, nearly 15 minutes each week. Cue “Here Comes the Sun.” http://www.sunrisesunset.com/

By February 29th, the Sun transits 9.5 degrees higher up than on the 1st. The result is a gain of 1 hour of daylight by month’s end. – Kevin McKeown, Abqjournal
