Pick one task you repeat and usually think will take less time than it does.

Estimate and time a brief familiar task, including its setup.
15 minutes
Compare an estimate with an observed task duration and update the next calendar slot.

Replace a guess with useful data
- Measure one familiar task.
- Check it on another ordinary day.
- Plan using the observed range and leave some room.

Time activities before making a daily schedule
Why it matters
People with ADHD show timing differences in lab research, and NHS guidance suggests measuring everyday activities. Timing a familiar task gives you something to plan with, but this strategy's effect on lateness has not been established in isolation. A wrong estimate is useful data.
How to do it
- Pick one task you repeat, like getting out of the house.
- Guess how long it takes, then note when it starts and finishes.
- Count setup, finding things and switching over in the total.
- Plan the next attempt with what you saw, leaving room for it to vary.
Putting it into practice
In real life
- Include finding shoes and locking the door when timing your departure.
- Measure reading and replying to an email, not only typing the reply.
Watch out for
- Common mistakeTiming everything is extra work. Start with one task you repeat.
- Common mistakeOne unusually fast attempt is a shaky guide. Compare a few ordinary ones.

General information about ADHD, not a diagnosis or an individual treatment plan. Tailoring changes the order of suggestions; it does not assess you. Medication decisions belong with you and a qualified clinician.
