Time blindness: why “I have two hours” turns into “I’m late”

2:00pm. You have to leave at 4. Plenty of time. 2:30, still plenty, one video. 3:15, you should start getting ready… soon. 3:55: where are your shoes? Where is your everything? 4:10: “so sorry, 5 mins away!” You were not five minutes away.

What is time blindness?

“Time blindness” is a phrase many people with ADHD use for difficulty sensing time passing. Time doesn’t flow; it jumps. There’s “now”, and there’s “not now”, and the space in between disappears. It’s why two hours can feel like ten minutes, and ten minutes of waiting can feel like two hours.

It isn’t rudeness and it isn’t not caring. Most people who run late feel terrible about it.

Five small fixes that help

• Set the alarm for the start, not the deadline. Don’t set “leave at 4”. Set “start getting ready at 3:15”. The getting-ready part is where time vanishes.
• Make time visible. An analogue clock in every room, or a visual timer you can see shrinking, works better than a number on a phone.
• Measure tasks in songs. “Getting dressed takes three songs.” Put on a playlist and you’ll feel where you are.
• Pack the night before. Shoes, keys, bag by the door. Your future self will think you’re a genius.
• Add a buffer, then add another. Whatever you think it takes, add 15 minutes. Busy brains tend to estimate the best-case version.

Try this: next time you have somewhere to be, write “START GETTING READY” on a sticky note with a time, and put it on your phone.

Tag the friend who’s always “5 minutes away”

They’re not ignoring you. Their clock just jumps. Send them this with love (and maybe tell them the meeting starts 15 minutes earlier).

This is friendly, general information, not medical advice. If you’re struggling, talk to a doctor or someone you trust.
