# How to plan your day with ADHD, and adjust when it changes

> Plan your day with ADHD using six flexible steps, a sample schedule, and a simple way to recover when tasks run late. Start on paper, with room to change.

To plan your day with ADHD, start with the commitments that already take up time. Add a few specific tasks, leave gaps, and decide what you will move if something runs late.

You can do this on paper, in a calendar, or on a dial. This is a practical approach to try and adjust, not a clinically tested six-step programme. I make Reassign, so the product example at the end is mine. The schedule below works without it.

## Six steps for a day you can adjust

1. **Choose up to three priorities.** One demanding task, one necessary task, and something for you can be a useful starting point. Write them down where you will see them. Make each specific: “draft the first section” is easier to start than “work on project.” Keep the rest on a separate list. On a packed day, one priority may be enough.
2. **Add your fixed commitments.** Work, classes, appointments, meals, travel, sleep. Include the time it takes to get ready and get there. A 9am meeting across town occupies more than its calendar slot. These commitments show how much room remains. The [time blocking guide](https://reassign.ai/resources/time-blocking) covers the mechanics of drawing those blocks.
3. **Estimate from a previous attempt.** If the last ordinary version of a task took 50 minutes, give it 50 minutes. Add setup time if that was not included. If the task is new, schedule a short first session and note what you get through. Research on the [planning fallacy](https://bear.warrington.ufl.edu/brenner/mar7588/Papers/buehler-et-al-1994.pdf) found that people often focused on their plans rather than relevant past experience when predicting completion times. That research was not ADHD-specific; it supports checking your estimates against experience, not adding a fixed percentage.
4. **Match the work to your energy.** A free slot is not the same as a good slot. Where your commitments allow, put demanding work in a window when you usually feel alert. Give lower-energy windows lighter tasks or rest. If your best hour is already booked, reduce the task to a manageable first action. [Energy-based planning](https://reassign.ai/resources/energy-based-planning) explains this approach in more detail.
5. **Leave room between blocks.** Keep some available time unassigned for transitions, interruptions, and overruns. For example, try a 15-minute gap after a demanding session. That is a starting experiment, not an ADHD rule. If you repeatedly use more, leave more next time. If fixed commitments fill the day, reduce optional work before taking the time from meals or sleep.
6. **Choose a time to review.** Try five to ten minutes in the evening or morning. Put the plan somewhere visible and check it after a cue that already happens, such as breakfast or lunch. The review only needs to answer: what still matters, what fits, and what moves?

## An example ADHD daily schedule

This is an illustrative day for someone working from home with some control over their hours. It is not a target for how much you should accomplish. Shift work, classes, care responsibilities, and different sleep patterns will change the shape.

Today's three priorities: draft a proposal section, send an invoice, and take a walk.

| Time | Plan | Why it is here |
| --- | --- | --- |
| 7:30–9:00 | Breakfast, get ready, start work | Real preparation time |
| 9:00–10:00 | Draft the proposal's first section | The demanding priority, in an alert window |
| 10:00–10:15 | Break | A transition before the meeting |
| 10:15–11:00 | Client meeting | Fixed commitment |
| 11:00–11:30 | Prepare and send the invoice | The necessary priority |
| 11:30–12:15 | Unassigned | Room for an overrun or follow-up |
| 12:15–13:00 | Lunch | A commitment worth keeping |
| 13:00–14:00 | Routine work and replies | Lighter work after lunch |
| 14:00–14:30 | Walk | Time for you, with an actual slot |
| 14:30–16:30 | Remaining work commitments | Work already owed, including breaks as needed |
| After 16:30 | Evening commitments, dinner, rest, sleep | Add your real commitments before adding more work |

The invoice estimate comes from a previous attempt. The proposal block promises a first section, not a finished proposal. The empty slot has a job too: keeping one overrun from taking the rest of the day with it.

## When the meeting runs 45 minutes late

The meeting finishes at 11:45 instead of 11:00. The invoice has not started. Lunch is still at 12:15.

Move the invoice to **11:45–12:15**. Its duration stays 30 minutes. The spare slot absorbs the delay, and lunch and the walk stay where they were.

If the meeting runs until 12:15, that buffer is gone. Keep lunch. If the invoice is due today, move it to 13:00–13:30 and defer 30 minutes of nonurgent replies. If those replies are also time-sensitive, renegotiate a commitment or reduce its scope. Moving everything later only hides the clash.

When the whole morning disappears, start from now. Look at the next fixed commitment and choose one action that fits before it. There is no need to recreate the missed morning first.

At the end of the day, compare [what you planned with what happened](https://reassign.ai/resources/daily-review-planned-vs-lived). Keep the useful estimate. Change the one that was wrong.

## What the 1-3-5 and 30% rules can tell you

[The Muse's 1-3-5 method](https://www.themuse.com/advice/a-better-todo-list-the-135-rule/) limits a daily list to one large task, three medium tasks, and five small tasks. It is a way to choose, not a requirement to complete nine tasks. Our three-priority starting point is also adjustable.

The “30% rule” needs more care. [Russell Barkley's interview about organising children with ADHD](https://www.littlehomeorganised.com.au/organising-children-with-adhd/) discusses an approximate delay in children's executive development. That is a different subject from how much of an adult's day to schedule. Do not use it to calculate your available hours.

Neither that discussion nor the planning-fallacy paper establishes that everyone with ADHD should add 30% to estimates or leave a third of the day empty. Your own record of transitions and overruns is a more useful way to choose a buffer.

## Try the shape before choosing the app

A [circular day planner](https://reassign.ai/resources/circular-planner-for-adhd) draws duration as space: a two-hour block takes twice the room of a one-hour block. If [time blindness](https://reassign.ai/resources/what-is-time-blindness) makes a list hard to translate into hours, that is a format worth trying.

Print the [free 24-hour planner](https://reassign.ai/circular-day-planner) and draw tomorrow by hand. Add your fixed commitments first, then one to three priorities and some breathing room. Mark the current hour when you check back.

[Reassign](https://reassign.ai/) puts that dial on screen. Drag a block to move it, see the current time with the now indicator, and sync two-way with Google Calendar, Outlook, and Todoist on Pro. The optional [energy curve](https://reassign.ai/features/energy) is a prediction from logged sleep and check-ins, not a measurement of your focus. No streaks or guilt counters. A missed day resets nothing.

If you want the apps compared rather than the method, [the best time blocking apps for ADHD](https://reassign.ai/resources/best-time-blocking-apps-adhd) compares planning styles, prices, and limits, with a trial checklist.

Start with a day you can change.

## FAQ

### What is the 1-3-5 rule?

It means choosing one large task, three medium tasks, and five small tasks for a day. The Muse presents it as a productivity technique, not an ADHD treatment. Nine tasks may still be too many around work, care, or classes. Use fewer when that is what fits. The original explanation is linked in this guide.

### What is the 30% rule for ADHD?

The phrase can refer to different ideas. Russell Barkley's clinical discussion of children's executive development is separate from advice to add 30% to task estimates or leave a percentage of the day empty. It does not establish a daily scheduling formula. The sources discussed in this guide do not validate a universal buffer percentage for adults with ADHD. Start with room between tasks and adjust it from experience.

### What does a good daily schedule for ADHD look like?

Start with fixed commitments, add a few specific tasks, and leave visible gaps. Include food, travel, rest, and preparation. The example in this guide shows three priorities inside a working day, then moves one when a meeting overruns. Adapt the hours to your own commitments and energy.

### What if I have no idea how long a task takes?

Plan a short first session with a clear action, such as opening the brief and writing three questions. Record how long that took and what remains. Use what you learn to size the next session instead of promising to finish an unknown amount of work.

### What if my day is already full?

Do not add three more tasks to a day that has no room. Choose one small action, reduce the scope of a task, or decide what can wait. Keep essential commitments and rest visible. A planner can show a capacity problem; it cannot create extra hours.

### Should I plan at night or in the morning?

Choose the time you are most likely to return to. An evening plan can make tomorrow easier to start; a morning plan can work better if evenings are unpredictable. Keep the review short and attach it to a cue you already have, such as breakfast or closing your laptop.
