Time blindness: why ADHD makes time feel slippery

“Time blindness” is the informal name for something a lot of people with ADHD know intimately: an unreliable internal sense of how much time has passed and how long things will take. It’s not laziness or not caring — it’s a difference in how attention and time-perception work together.

What it actually feels like

• Two hours vanish into a task that felt like twenty minutes.
• You consistently underestimate how long the commute, the email, or the errand will take.
• Time splits into “now” and “not now,” so anything not urgent stays invisible until it suddenly isn’t.

Why it happens

Estimating and tracking time draws on the same executive-function and attention systems that ADHD affects. When attention is dysregulated, the internal clock drifts — which is why external structure tends to help far more than “just try harder.”

Practical ways to work with it

• Make time visible: analog clocks, visual timers, and countdowns turn an abstract sense of time into something you can see.
• Time-box, don’t open-end: “I’ll work until 3:00” beats “I’ll work until it’s done.”
• Add a buffer, then add more: whatever you estimate, pad it — you’re probably underestimating.
• Anchor tasks to fixed events: “after lunch,” “before the school run,” so they attach to something concrete.
