How many minutes of daylight have we lost since the Summer Solstice?
The Summer Solstice which occurred on Friday, June 21 at 11:54 a.m. This is the longest day of the year in terms of daylight. Here in Columbus we receive 14 hours, 17 minutes and 3 seconds of daylight on that day.
The sun rises at 6:33 a.m. and the sun set at 8:50 p.m. on June 21.
How much daylight have we lost since then?
For Wednesday, August 15, the sun rises in Columbus at 7:03 a.m. and the sun sets at 8:24 p.m. This gives us a total amount of daylight for that day at 13 hours, 20 minutes and 32 seconds. After a few simple math calculations, we have lost a total of 57 minutes to darkness.
This simple calculation can be done for the entire period where we are losing daylight every day until the Winter Solstice, known for being the shortest day of the year.
Taking data from June 21 again, the amount of daylight we receive is 14 hours, 17 minutes and 3 seconds.
For the Winter Solstice, which occurs Friday, December 21 at 5:23 p.m. we receive a total amount of daylight at 10 hours, 1 minute and 5 seconds.
Calculating that, from the start of summer to the start of winter, here in Columbus we lose 256 minutes (4 hours and 16 minutes) to darkness over this period from June to December.
During the months of September and October we are constantly losing roughly 2 minutes per day as we near the Autumnal Equinox which we receive “equal” amount of daylight and darkness.
You might ask yourself, how does Daylight Saving Time play a role into this? While Daylight Saving Time ends on Sunday, November 4 it doesn’t effect the amount of daylight.
Daylight Saving Time only changes the time at which the sun will rise and set by falling back an hour. The amount of daylight is unchanged; however, with the change in time more light will be available in the morning.
