What is time blindness in ADHD? 

ADHD time blindness refers to a neurological difficulty with sensing and managing the passage of time. It’s not simply being forgetful or distracted, it’s a real struggle with internal time awareness. People with ADHD often experience time in extremes: either “now” or “not now,” which makes it hard to plan ahead or accurately judge how long tasks will take. 

This lack of internal timing leads to poor time awareness, frequent delays, and a tendency to be late to appointments even with the best intentions. It’s a core aspect of ADHD’s executive function challenges and often affects work, school, and relationships.

Recognising and Managing Time Blindness 

Here’s how ADHD time blindness shows up in everyday life and what can help: 

Losing track of time during tasks  

Whether hyperfocused or distracted, time slips away quickly. This leads to missed transitions, delays in starting the next task, and regular surprises when the clock is checked. 

Difficulty anticipating future deadlines 

 The future often feels abstract or unreal, so deadlines don’t trigger urgency until they are right on top of you. This is a common result of poor time awareness. 

Chronic lateness despite trying  

People with ADHD are often late to appointments, not because they don’t care, but because time estimations are unreliable. Travel time, prep time, and task switching can all be misjudged. 

Struggles with executive function  

Executive function affects planning, prioritising, and managing tasks across time. Without support, time blindness can snowball into daily chaos. 

ADHD time blindness can improve with tools that make time visible, routines that anchor daily life, and strategies that turn abstract planning into concrete action.
