We're going to be losing 83 minutes of daylight in the next month. Jeebus. We've already lost about three hours of light since the days started getting shorter at the end of June, and we'll continue our descent into darkness until this year's winter solstice, which comes December 21. Perhaps those numbers make you notice we're losing more daylight this month than the previous three--you're right! Daylight, not near either pole, is a sinusoidal function. [WGN]
