Why time blocking works (even when nothing else does)

Time blocking can help you take back control of your time, whether you’re neurodivergent or just overwhelmed by too much to do.

No items found.

Most people with ADHD struggle with some aspect of time management—which includes planning, prioritizing, and estimating the length of tasks. It is the primary reason my clients cite for seeking an ADHD coach in the first place, and these struggles with time management can have some of the most devastating impacts on our career and professional relationships. While no one ADHD tool or technique can completely fix our relationship with time, the technique that I’ve personally found the most helpful for supporting the struggles with time management I experience due to my ADHD is time blocking.

What is time blocking?

Time blocking is a time management technique that makes our tasks and our time visible by scheduling upcoming tasks into specific blocks of time and placing those in our calendar. Most of these blocks can be moved to fit our changing energy levels, need for stimulation, and struggles with executive function. The way time blocking makes tasks and time visible, as well as the flexibility that comes from moving the blocks as needed, is what makes the technique such a powerful tool for people with ADHD.

More than that however, time blocking can also support other struggles common to the ADHD experience, including decision paralysis, our troubles transitioning between tasks, and our struggles getting started. In particular, time blocking can:

  • Stop us from overbooking ourselves. Planning specific blocks of time for specific tasks makes how much time we actually have visible to us. Seeing our calendar full of tasks already serves as an added barrier to taking on more. This empowers you to set and maintain boundaries or, as René Brooks might say, Guard your yes.
  • Reduce decision fatigue. Decisions are hard. In particular, deciding what we want or need to do next can feel next to impossible. Having a plan (or at least a default) reduces decision fatigue and provides a clear direction for our energy.
  • Reduce the number of transitions. Transitioning from one task to another takes a lot of time and energy for ADHD’ers (and autistic folks). This is especially true if the tasks we’re transitioning between are wildly different. Grouping like tasks and blocking them into our schedule ahead of time reduces the number of times we need to transition.
  • Encourage us to get started. Having a scheduled time to work on a task (and a scheduled end time) provides just a little added encouragement to get the task started in the first place. While this isn’t a cure-all for initiation woes, this slight push can make the difference between stagnation and progress.
  • Teach time estimation skills. ADHD’ers are more likely to struggle to estimate how long tasks take to complete. This is part of larger issues with time agnosia (or time blindness), but time blocking provides a support. It serves as a visible record of how long we expect tasks to take. By comparing these estimations with how long tasks actually took we can learn to be more accurate in our estimates.

Okay...but how?

Step 1: Brain Dump.

Since time blocking is the practice of assigning an estimated amount of time to upcoming tasks and events and placing them in a calendar, the first step needs to involve knowing what the upcoming tasks and events are! My favourite way to do this is a brain dump, where I write everything swirling around in my head to be sorted later.

Step 2: Schedule the unmovables

Whether it’s a dead.line at work or your next appointment with your therapist, some things have to happen at a specific time; no question about it. Schedule these unmovables first! When you do, include travel and transition time around the event. If you don’t have a good idea of how much travel or transition time you need, a good guideline is doubling or tripling your estimate.

A note for the future: People who frequently time block often set blocks of time for meetings and appointments to reduce transitions further.

Step 3: Add blocks based on priority.

Using the brain dump (or to-do list) as a guide, assign time for the highest priority tasks. If you’re anything like me, you’re likely to underestimate how long tasks will take, so schedule more time than you think you’ll need… and more time again to transition between this task and the next. Don’t be afraid to schedule these right into the calendar. After all, they can be moved; that’s the point!

Step 4: Group similar tasks.

Struggles with task initiation (and autistic inertia) feed off transitions between tasks. The more we start and stop, the more energy we spend just transitioning between tasks and the harder the tasks seem, making it more difficult to stay on task. Grouping similar tasks together (for example, social tasks with social tasks, or writing tasks with writing tasks) can help us conserve momentum and make tasks easier to start, work on, and finish!

Common mistakes to avoid

Mistake #1: Making your schedule a prison.

One of the most frequent concerns about time blocking is how rigid the system can seem. Time blocking seems especially rigid if you are used to using your calendar primarily for appointments or other mandatory events. If this sounds like you, time blocking is as much about changing your relationship with calendars as it is about pre-planning your tasks for the next day (or week) into specific blocks of time.

Instead of seeing scheduled blocks as an obligation or commitment, try viewing the blocks as your default decision. If you’re compelled to change tasks, whether by distraction, struggles with getting started, or seeking novelty, you are free to move the blocks to adapt your schedule to your needs. However, unless the associated tasks have been completed (or delegated), the blocks usually can’t be removed in their entirety. This makes the consequences of changing our schedule visible, and this prevents us from procrastinating ourselves into a crisis bigger than we can handle.

Mistake #2: Expecting your future self to be superhuman.

For whatever reason, there is a tendency to imagine that our future selves are superhuman. They can get things done faster than us; they never get tired or need breaks; and they never have any trouble getting started. That will never be true, and it changes the way that we need to block our time.

First, we need to accept that we’re probably going to underestimate how long tasks are going to take us, and multiply our time estimation by a factor of 2, 3, or sometimes 4 times . Over time, the size of this multiplier may reduce as we learn how to make better estimates, but as this struggle with time estimation is a major part of the time agnosia (also known as time blindness) experienced by people with ADHD, it may never go away entirely.

Second, we need to accept that we will always need extra time to transition between one task and the next, and schedule this transition time right into our schedule. While the amount of transition time varies between people and between tasks, a guideline for scheduling transition time is to include 5 minutes of transition time for every 30 minutes of the previous task.

Mistake #3: Only using time blocking.

No matter what anybody says, there’s no solution to the struggles of ADHD that works for everyone, all the time, in all contexts. While time blocking helps me get started on my tasks and helps me avoid overscheduling myself, my ability to procrastinate still knows no bounds and hyperfocus listens to no calendar.

Time blocking alone isn’t going to completely fix your relationship with time, and it can’t be expected to. Combining time blocking with other techniques aimed at other aspects of time management ADHD’ers struggle with, such as the pomodoro technique, timers, or alarms, can help.

How to start time blocking

You can start with any calendar or planning tool that feels accessible to you. Apps like Tiimo are designed specifically to make time blocking visual and intuitive, especially for neurodivergent brains, but you can also use a basic calendar app or even draw blocks in a notebook. The key is finding something that makes your time visible and easy to adjust.

1. Brain dump what's on your plate

Get all your tasks, appointments, worries, and random thoughts out of your head and onto paper or a digital document. Don't worry about order, importance, or feasibility yet. The goal is simply getting everything visible so your brain can stop trying to remember it all.

2. Schedule the fixed events first

These are the things that happen at specific times: meetings, appointments, classes, or events. Make sure to include travel and transition time between them. If you tend to underestimate how long it takes to get from place to place (or from task to task), try doubling your estimate to start. Better to have extra time than to spend your day feeling constantly behind.

3. Add your highest priority tasks

Look at your brain dump and pick one to three things that feel most important or urgent for the day. If you're struggling to prioritize, try using the Eisenhower Matrix to sort tasks by importance and urgency. Block time for your chosen priorities next, placing them during your peak energy hours if possible. If you're prone to underestimating how long things take, add buffer time. If you're not sure where to start, try blocking the task you've been avoiding first, then pair it with something easier before or after as a reward.

4. Group similar tasks together

It takes significant mental energy to switch between different types of work. You can reduce that cognitive cost by batching similar tasks, like emails, errands, writing, chores, into the same block. This is especially helpful if you struggle with transitions or have trouble building momentum once you stop.

5. Don't forget breaks and recovery time

Rest isn't optional, and it's not earned through productivity. Build breaks between blocks, especially after tasks that drain you mentally or emotionally. If you live with chronic fatigue, chronic illness, or variable capacity, include generous transition and recovery time. This is essential support for your future self.

Real examples of time blocking in action

When time blocking is working well, it often feels less like a strict schedule and more like a supportive scaffold that helps you navigate your day. Here are a few ways it can address common struggles:

  • If time disappears on you: Block how long you think a task will take, then track how long it actually takes. This builds awareness over time and helps you make better estimates. You might discover that answering emails takes twice as long as you thought, or that you consistently underestimate transition time.
  • If you can't get started: Seeing a task on the calendar with a clear start and end time can reduce the friction of beginning. The bounded nature of the block makes it feel more manageable. Even better if you add a five-minute warm-up activity before it, like clearing your desk or making tea.
  • If everything feels urgent: Planning blocks ahead of time helps you separate what's truly important from what's just loud or demanding immediate attention. When you're not in crisis mode, you can think more clearly about priorities.
  • If transitions derail you: Fewer task switches means less energy lost to mental gear-shifting. Block similar tasks together, or set up bridges like a specific playlist, a snack, or a short walk to ease the change between different types of work.
  • If your energy shifts throughout the day: Move blocks around as needed. You're not locked into your original plan. What matters is that the visual map helps you orient yourself and make conscious choices about how to spend your time.

Common pitfalls (and how to adjust)

One of the biggest misconceptions about time blocking is that you have to follow it exactly or you've failed. That kind of all-or-nothing thinking defeats the entire purpose and turns a supportive tool into another source of shame.

You're allowed to move blocks. You're allowed to skip blocks. You're allowed to completely abandon your plan when life happens. What matters is that you've externalized your intentions so you can see what's happening, instead of trying to track everything internally while juggling a million other things.

Here are a few patterns to watch for as you develop your practice:

  • Overscheduling yourself: If your calendar has no white space, it's not sustainable. You're setting yourself up for constant stress and inevitable "failure." Start with fewer blocks and more buffer time than you think you need. You can always add more structure later.
  • Skipping breaks or treating them as optional: Breaks are part of the system, not a reward you earn through productivity. Make them visible on your calendar and treat them like you would any other important appointment. Your brain needs downtime to function well.
  • Expecting your future self to be superhuman: Block time based on your real capacity and energy patterns, not your ideal day or what you think you "should" be able to handle. If you often plan with unrealistic optimism, try doubling or tripling your time estimates until you have more accurate data about how you actually work.
  • Using the plan as a weapon against yourself: Time blocking is meant to support you, not control or punish you. If it starts feeling like a guilt machine or a constant reminder of your "failures," step back and adjust your approach. The tool should serve you, not the other way around.

Your time, your way

Time blocking will never make you perfectly productive, and that's exactly the point. This approach gives your time structure you can see, follow when it serves you, and adapt when life inevitably throws curveballs. That flexibility is powerful for anyone juggling competing demands, but especially for people whose brains don't naturally keep track of time or struggle with executive function.

If you've tried and failed to stick to rigid schedules before, you're not broken or bad at time management. You might simply need a different kind of tool, one that works with your brain's natural patterns instead of fighting against them. Time blocking can be that tool when it's used with self-awareness, flexibility, and genuine compassion for yourself as a beautifully imperfect human navigating each day.

The goal was never to control every minute. The goal is to make your time visible so you can make conscious choices about how you spend it. Some days you'll follow your blocks closely. Other days you'll abandon them entirely. Both are completely valid ways to use this tool.

Your time belongs to you. Time blocking simply helps you see it more clearly and use it more intentionally. And in a world that constantly demands your attention, that clarity becomes its own form of rebellion.

Mistake #2: Expecting your future self to be superhuman.

For whatever reason, there is a tendency to imagine that our future selves are superhuman. They can get things done faster than us; they never get tired or need breaks; and they never have any trouble getting started. That will never be true, and it changes the way that we need to block our time.

First, we need to accept that we’re probably going to underestimate how long tasks are going to take us, and multiply our time estimation by a factor of 2, 3, or sometimes 4 times . Over time, the size of this multiplier may reduce as we learn how to make better estimates, but as this struggle with time estimation is a major part of the time agnosia (also known as time blindness) experienced by people with ADHD, it may never go away entirely.

Second, we need to accept that we will always need extra time to transition between one task and the next, and schedule this transition time right into our schedule. While the amount of transition time varies between people and between tasks, a guideline for scheduling transition time is to include 5 minutes of transition time for every 30 minutes of the previous task.

Mistake #3: Only using time blocking.

No matter what anybody says, there’s no solution to the struggles of ADHD that works for everyone, all the time, in all contexts. While time blocking helps me get started on my tasks and helps me avoid overscheduling myself, my ability to procrastinate still knows no bounds and hyperfocus listens to no calendar.

Time blocking alone isn’t going to completely fix your relationship with time, and it can’t be expected to. Combining time blocking with other techniques aimed at other aspects of time management ADHD’ers struggle with, such as the pomodoro technique, timers, or alarms, can help.

How to start time blocking

You can start with any calendar or planning tool that feels accessible to you. Apps like Tiimo are designed specifically to make time blocking visual and intuitive, especially for neurodivergent brains, but you can also use a basic calendar app or even draw blocks in a notebook. The key is finding something that makes your time visible and easy to adjust.

1. Brain dump what's on your plate

Get all your tasks, appointments, worries, and random thoughts out of your head and onto paper or a digital document. Don't worry about order, importance, or feasibility yet. The goal is simply getting everything visible so your brain can stop trying to remember it all.

2. Schedule the fixed events first

These are the things that happen at specific times: meetings, appointments, classes, or events. Make sure to include travel and transition time between them. If you tend to underestimate how long it takes to get from place to place (or from task to task), try doubling your estimate to start. Better to have extra time than to spend your day feeling constantly behind.

3. Add your highest priority tasks

Look at your brain dump and pick one to three things that feel most important or urgent for the day. If you're struggling to prioritize, try using the Eisenhower Matrix to sort tasks by importance and urgency. Block time for your chosen priorities next, placing them during your peak energy hours if possible. If you're prone to underestimating how long things take, add buffer time. If you're not sure where to start, try blocking the task you've been avoiding first, then pair it with something easier before or after as a reward.

4. Group similar tasks together

It takes significant mental energy to switch between different types of work. You can reduce that cognitive cost by batching similar tasks, like emails, errands, writing, chores, into the same block. This is especially helpful if you struggle with transitions or have trouble building momentum once you stop.

5. Don't forget breaks and recovery time

Rest isn't optional, and it's not earned through productivity. Build breaks between blocks, especially after tasks that drain you mentally or emotionally. If you live with chronic fatigue, chronic illness, or variable capacity, include generous transition and recovery time. This is essential support for your future self.

Real examples of time blocking in action

When time blocking is working well, it often feels less like a strict schedule and more like a supportive scaffold that helps you navigate your day. Here are a few ways it can address common struggles:

  • If time disappears on you: Block how long you think a task will take, then track how long it actually takes. This builds awareness over time and helps you make better estimates. You might discover that answering emails takes twice as long as you thought, or that you consistently underestimate transition time.
  • If you can't get started: Seeing a task on the calendar with a clear start and end time can reduce the friction of beginning. The bounded nature of the block makes it feel more manageable. Even better if you add a five-minute warm-up activity before it, like clearing your desk or making tea.
  • If everything feels urgent: Planning blocks ahead of time helps you separate what's truly important from what's just loud or demanding immediate attention. When you're not in crisis mode, you can think more clearly about priorities.
  • If transitions derail you: Fewer task switches means less energy lost to mental gear-shifting. Block similar tasks together, or set up bridges like a specific playlist, a snack, or a short walk to ease the change between different types of work.
  • If your energy shifts throughout the day: Move blocks around as needed. You're not locked into your original plan. What matters is that the visual map helps you orient yourself and make conscious choices about how to spend your time.

Common pitfalls (and how to adjust)

One of the biggest misconceptions about time blocking is that you have to follow it exactly or you've failed. That kind of all-or-nothing thinking defeats the entire purpose and turns a supportive tool into another source of shame.

You're allowed to move blocks. You're allowed to skip blocks. You're allowed to completely abandon your plan when life happens. What matters is that you've externalized your intentions so you can see what's happening, instead of trying to track everything internally while juggling a million other things.

Here are a few patterns to watch for as you develop your practice:

  • Overscheduling yourself: If your calendar has no white space, it's not sustainable. You're setting yourself up for constant stress and inevitable "failure." Start with fewer blocks and more buffer time than you think you need. You can always add more structure later.
  • Skipping breaks or treating them as optional: Breaks are part of the system, not a reward you earn through productivity. Make them visible on your calendar and treat them like you would any other important appointment. Your brain needs downtime to function well.
  • Expecting your future self to be superhuman: Block time based on your real capacity and energy patterns, not your ideal day or what you think you "should" be able to handle. If you often plan with unrealistic optimism, try doubling or tripling your time estimates until you have more accurate data about how you actually work.
  • Using the plan as a weapon against yourself: Time blocking is meant to support you, not control or punish you. If it starts feeling like a guilt machine or a constant reminder of your "failures," step back and adjust your approach. The tool should serve you, not the other way around.

Your time, your way

Time blocking will never make you perfectly productive, and that's exactly the point. This approach gives your time structure you can see, follow when it serves you, and adapt when life inevitably throws curveballs. That flexibility is powerful for anyone juggling competing demands, but especially for people whose brains don't naturally keep track of time or struggle with executive function.

If you've tried and failed to stick to rigid schedules before, you're not broken or bad at time management. You might simply need a different kind of tool, one that works with your brain's natural patterns instead of fighting against them. Time blocking can be that tool when it's used with self-awareness, flexibility, and genuine compassion for yourself as a beautifully imperfect human navigating each day.

The goal was never to control every minute. The goal is to make your time visible so you can make conscious choices about how you spend it. Some days you'll follow your blocks closely. Other days you'll abandon them entirely. Both are completely valid ways to use this tool.

Your time belongs to you. Time blocking simply helps you see it more clearly and use it more intentionally. And in a world that constantly demands your attention, that clarity becomes its own form of rebellion.
