Time blindness: how it can be 4:17 already
For a lot of ADHD brains, time isn't a background hum you can feel passing. It's information you have to actively go and check.

You sat down at what felt like ten minutes ago.
It is now 4:17.
Nothing dramatic happened in between. You didn't lose consciousness. You were, in some sense, there the entire time — and yet the hours are unaccounted for in the way that only ADHD hours can be.
Time perception isn't a character trait
Research on ADHD consistently finds differences in time estimation and time reproduction tasks — judging how long something took, and producing an interval of a given length. In practice this means the internal sense of duration that most people run quietly in the background is less reliable, so time has to be checked deliberately rather than felt.
That has knock-on effects everywhere. If you can't feel that twenty minutes has passed, you can't feel that you should leave. If you can't estimate that the task will take ninety minutes rather than twenty, your plan for the day was wrong before it started.
The two failures that cause most trouble
The first is time disappearing during an absorbing activity — reading, gaming, a work task that finally clicked. The absorption is not the problem. The absence of any interruption is.
The second is the opposite: time disappearing before an activity, in the strange holding pattern that happens when you have something at 3pm and it is currently 1:40, so the entire intervening period becomes unusable.
Both are helped by the same principle: put time outside your head where you can see it.
Making time visible
Analog clocks in the rooms where time goes missing. Visual timers that show remaining time as a shrinking block of colour rather than a number you have to interpret. Alarms with names, so the alarm tells you what it's for.
Anchor events rather than clock times where you can: after dinner, before the school run, when the podcast ends. Anchors are easier to perceive than abstract numbers.
And build in a departure sequence, not a departure time. "Leave at 8:15" is a single point you will miss. "Shoes at 8:05, bag at 8:10, door at 8:15" is a chain that can catch you.
Don't just try harder. Make it easier to do.
