GRAND RAPIDS, Mich. (WOOD) — August is coming to a close and the length of day is already shrinking. At the height of summer, West Michigan boasted sunsets after 9 p.m. with only four hours of complete darkness untouched by civil or nautical twilight.
Since the solstice, we have lost almost two hours of daylight from our days.
August 23rd is particularly interesting because it marks the exact day when we have lost an even amount of minutes from our sunrise and from our sunset. As of Tuesday, the sunrise was exactly 54 minutes later than it occurs at solstice and the sunset is exactly 54 minutes earlier.
The Fall Equinox officially begins at 9:03 p.m. on September 22nd of this year. By that point in time, West Michigan will lose an additional hour and 25 minutes of daylight from now.
