It's 7:40pm in mid-September and it's already getting dark outside your window in Michigan. A month ago, 7:40 felt like the middle of the evening. Now it feels like the day is over, and you're hit with a specific, sinking feeling: I didn't do anything today.
You did things. You know you did things. But the light is gone, and with it goes any sense that the day counted.
What's Actually Happening
If you have ADHD, you probably already know that time doesn't feel the way it seems to feel for other people. It's not a steady flow. It's "now" and "not now," and the boundary between them is fuzzy at best. Clinicians call this time blindness. What it means in practice is that your brain uses external cues, light, meals, other people's schedules, to figure out where you are in the day, because the internal clock isn't reliable.
For most of the summer, the light told you it was still "day" until 9pm. That gave you a long runway. Now the runway is shrinking by a couple of minutes every single day, and your brain, which was calibrated to the summer version, keeps getting the message that the day ended before you were ready.
So you feel like you lost time. And in a way, you did, not the actual hours, but the felt hours, the ones that existed when the light said you still had time.
What This Looks Like
You look up, it's dark, and you feel a jolt of panic even though nothing is actually due
The evening feels "used up" before you've done the thing you were saving it for
You start rushing at 6pm in a way you didn't in July, without knowing why
You go to bed feeling behind, even on days where you got a lot done
You've started thinking about winter with something close to dread, and it isn't even October
Why This Hits ADHD Brains Specifically
Your sense of "time remaining" is external, not internal. Neurotypical brains have a somewhat reliable internal sense of how much day is left. ADHD brains borrow that sense from the environment, and when the environment changes, the sense changes with it.
The "wasted day" feeling is about visibility, not productivity. You didn't do less. You just can't see what you did, because the day's evidence gets erased when the light goes. That's why it feels like nothing happened even when things did.
Urgency is your fuel, and darkness triggers it. A lot of ADHD adults run on urgency. The earlier sunset creates artificial urgency ("the day's ending, I have to do something now"), which can feel productive in the moment and then leave you wired and unsettled at 9pm.
It compounds with everything else September does. Less light also means shifted melatonin, lower energy, and less sensory tolerance. So you're processing the "day is over" signal with less capacity to handle it.
What Actually Helps
Anchor the day to something other than light. If sunset is now your "day is over" cue, pick a different one. A specific evening activity, a specific time, a specific transition ritual. Something you control, that doesn't move two minutes earlier every day.
Write down what you did, before it gets dark. This sounds small and it isn't. The "wasted day" feeling comes from not being able to see the evidence. Three lines on a sticky note at 5pm gives the evidence somewhere to live that darkness can't erase.
Move the thing you were "saving the evening for" to earlier. If you keep losing the evening to the sunset panic, stop scheduling important things for the evening. Give them the daylight instead.
Name it when it happens. "It's dark and my brain is telling me the day is over. That's the light, not reality." Naming the mechanism takes some of its power away.
What If I Know This and It Still Gets Me Every Year?
That's the thing about time blindness. Knowing about it doesn't fix it, because it's not a knowledge problem. It's a perception problem, and perception doesn't update from information. It updates from new cues. If this happens every September and every September you think "I should be past this by now," you're holding yourself to a standard your brain can't meet. It's not a character flaw. It's a clock that runs differently.
How Therapy Can Help
At Ideal Psychology Group, we work with ADHD adults across Michigan on exactly this kind of thing, the stuff that isn't in the diagnostic criteria but shapes daily life anyway. Our clinicians are neurodivergent-affirming and can help you build structures that work with your brain rather than against it. Sessions are fully virtual, so there's no drive in the dark to get there.
Frequently Asked Questions
Is time blindness a real ADHD symptom?
Yes. Difficulty perceiving and tracking time is a well-documented feature of ADHD, and it affects everything from being late to feeling like a day "disappeared."
Why does the earlier sunset affect me more than other people?
If your sense of time depends heavily on external cues like light, changes to those cues affect you more directly than someone whose internal clock is more reliable.
Does this get worse in winter?
For many people, yes. The strategies here become more important as the days get shorter, which is why September is a good time to start rather than waiting for December.
Do you work with ADHD adults anywhere in Michigan?
Yes. We're fully virtual and see clients throughout the state, from Metro Detroit to Grand Rapids to the U.P.
If the dark keeps stealing your evenings and you can't figure out why it hits so hard, we'd love to help. 💛
