Time-blindness trainer
Find out how time feels to you, and how long things really take. Then plan with it.
What would you like to try?
Two short exercises. Start with either.
How this works, and why
Is time blindness real?
Yes, in the sense that it can be measured. Dozens of studies have asked people to judge, reproduce or produce stretches of time, and people with ADHD make larger errors on average, especially children. Research in adults is thinner and more mixed. “Time blindness” isn’t a medical term, but it describes the experience well: ten minutes and an hour can feel the same.
How to use your planning number
Most of us, ADHD or not, underestimate how long things take. The fix isn’t trying harder to guess; it’s correcting the guess. If your number is 1.6×, a task you’d call 30 minutes needs a 48-minute slot. Use it for leaving the house, for work estimates and for deciding what fits in an evening.
Other ways to make time visible
- A timer you can see from across the room, or a shrinking bar like the one in Unstick me.
- An analogue clock where you can see the hands move.
- Alarms for leaving, not for arriving: set them for when you need to put shoes on.
Common questions
What is time blindness in ADHD?
Difficulty sensing how much time has passed or how long things will take. Studies show people with ADHD make larger timing errors on average, especially when producing or reproducing time intervals.
Can this test tell me if I have ADHD?
No. Everyone misjudges time sometimes, and timing tests are not diagnostic. Use it to learn your own pattern and plan around it.
How do I get better at estimating time?
Guess, then measure, then correct. Keep a record of how long real tasks take compared to your guess, and multiply future guesses by your usual ratio.
