There is an old saying about making hay while the sun shines - a recognition that farm chores last as long as there is daylight. The last four weeks have been witness to my neighbors fetching their first cutting of hay; along with spreading manure, tilling, discing and planting. It has been a busy place here in flyover country.
We know that the summer solstice tomorrow marks the longest day of the year yet the latest sunset of 2025 doesn't occur on that date. Let me explain.

The solstice marks the farthest point of advance in the sun's relentless march to the north, delivering the maximum daylight hours of the year for the Northern Hemisphere and the minimum daylight hours of the year for the Southern Hemisphere. The solstice this month marks the beginning of summer here in the Northern Hemisphere and the winter in the Southern Hemisphere.
The word solstice literally translates to: sun standing still. Following this event the sun begins to march in the opposite direction and heads south with our daylight hours getting shorter. Daylight will continue to dwindle until December 21 - The dark days of the winter solstice - and the first astronomical day of winter after which the process reverses and repeats itself.
All of this aside, there is a curious paradox in play as a few evenings immediately following the solstice seemingly and inexplicably get brighter.
If you were to check your Farmers' Almanac sunset tables on pages 150 and 151 you would note that at latitude 40 degrees north the sunset occurs at 8:33 every day from June 21st thru July 3rd. On June 27th it will set a few seconds later compared to the 26th or 28th.
What gives?
We all know that following the solstice the days grow shorter so logically the sun should be setting earlier, no?
Here in the northern hemisphere, where you live halfway between the equator and the north pole, on the 27th of June the sun will set just a few seconds later. While this would seem to defy both logic and the science about days getting shorter; as a consequence of our elliptical orbit around the sun and the phenomenon astronomers call analemma the earth is several million miles farther from the sun and moving at the slowest speed around it. Which would explain the hiccup in the sun setting.
Most of you may not be making hay today; nevertheless, on Friday of next week enjoy a couple of extra seconds of sunlight as you take-in another sunset.
Cheers!
