# Time blocking: a simple guide with templates

Time blocking means planning your day as a row of blocks on a calendar, where each block holds one kind of work: a hard task, a batch of email, a break. Instead of working down a list and reacting to whatever arrives, you decide in advance when each thing happens, then fix the plan when the day changes.

That last part matters more than most guides admit. A time blocked day rarely runs exactly as planned. The point is to always know what the next block is for.

Roomie Cafe is a free focus timer you share with friends. We make it, and we mention it briefly near the end. Everything else here works with paper, a calendar app or anything in between.

## What time blocking is

Time blocking is a way of giving every part of your working day a job before the day starts. Cal Newport, the computer scientist who wrote *Deep Work*, made the method popular. He describes planning each workday on one sheet of paper: hours down the left, blocks of labeled work beside them, and room on the right to redo the plan when something breaks it. He spends 10 to 20 minutes each evening building the next day's blocks [1].

Most people use four kinds of block:

| Block type | What goes in it | Typical length |
| --- | --- | --- |
| Deep | One demanding task: writing, coding, studying, design | 60 to 120 minutes |
| Shallow | Email, messages, admin, small errands | 20 to 45 minutes |
| Buffer | Empty time that absorbs overruns and surprises | 15 to 30 minutes |
| Break | Food, a walk, nothing at all | 10 to 60 minutes |

The deep block is the one you protect. The buffer block is the one people skip, and then the whole plan collapses by lunch.

## Does time blocking work?

There is no large study of time blocking on its own, so be wary of anyone quoting a precise productivity boost. The wider research on time management is encouraging, though.

* A 2021 meta analysis in *PLOS ONE* found that time management is moderately related to job performance, academic results and wellbeing, and moderately linked to lower distress. The authors noted it seemed to help life satisfaction more than performance [2].
* Plans tied to a specific time and place work better than vague intentions. A 2006 meta analysis of 94 tests of these "when and where" plans, called implementation intentions, found a medium to large effect on reaching goals [3]. A calendar block is exactly that kind of plan.
* People reliably underestimate how long their own tasks take, a bias known as the planning fallacy. In the classic studies, the optimism disappeared when people were asked to connect their estimate to how long similar tasks took in the past [4]. That is the research case for buffers.

So the honest summary: deciding in advance when you will do something helps, and your first plan will be too optimistic.

## How to time block your day in 5 steps

1. **List what has to happen.** Write down this week's real commitments: deadlines, meetings, classes, the one big project. Keep it short.
2. **Place the fixed things first.** Meetings, school runs, the gym class. These are the walls your blocks fit between.
3. **Put your deep block where your energy is.** For many people that is the morning, before messages pile up. Give it one task, written as an action ("draft section 2"), not a topic ("report").
4. **Batch the shallow work.** Two shallow blocks a day, say late morning and late afternoon, usually cover email and admin. Outside them, messages wait.
5. **Add buffers and replan without guilt.** Leave at least one buffer block in the morning and one in the afternoon. When the day breaks the plan, take two minutes to redraw the rest of the day. Newport does this too [1]; the replan is part of the method.

At the end of the day, look at what actually happened. If your "one hour" blocks keep taking ninety minutes, make them ninety minutes.

## A sample time blocked day

Here is a realistic day for someone with a full time job and one project that needs real thought:

| Time | Block | Type |
| --- | --- | --- |
| 08:30 to 08:45 | Look at today's plan, adjust it | Shallow |
| 08:45 to 10:30 | Write the client proposal, section 2 | Deep |
| 10:30 to 10:45 | Break away from the screen | Break |
| 10:45 to 11:30 | Email and messages | Shallow |
| 11:30 to 12:00 | Buffer | Buffer |
| 12:00 to 13:00 | Lunch | Break |
| 13:00 to 14:00 | Team meeting | Fixed |
| 14:00 to 15:15 | Review data for the proposal | Deep |
| 15:15 to 15:45 | Buffer | Buffer |
| 15:45 to 16:30 | Admin, calls, small tasks | Shallow |
| 16:30 to 16:45 | Shut down: note where you stopped, plan tomorrow | Shallow |

The shut down block at the end is worth keeping. Writing down where you stopped makes tomorrow's first block easier to start.

## Copyable weekly time blocking template

Copy this table into a note or spreadsheet and replace the examples. One row per block, one column per day. Keep the deep blocks at the same time each day if you can; a fixed rhythm means less deciding.

| Block | Monday | Tuesday | Wednesday | Thursday | Friday |
| --- | --- | --- | --- | --- | --- |
| 08:30 Plan (15 min) | Plan the week | Plan the day | Plan the day | Plan the day | Plan the day |
| 08:45 Deep 1 (90 min) | Main project | Main project | Main project | Main project | Review the week's work |
| 10:15 Break (15 min) | Walk | Walk | Walk | Walk | Walk |
| 10:30 Shallow (45 min) | Email, messages | Email, messages | Email, messages | Email, messages | Email, messages |
| 11:15 Buffer (30 min) | Buffer | Buffer | Buffer | Buffer | Buffer |
| 13:00 Fixed | Meetings | Meetings | No meetings | Meetings | Meetings |
| 14:00 Deep 2 (60 min) | Second project | Learning | Main project | Second project | Learning |
| 15:00 Buffer (30 min) | Buffer | Buffer | Buffer | Buffer | Buffer |
| 15:30 Shallow (45 min) | Admin | Admin | Admin | Admin | Admin |
| 16:15 Shut down (15 min) | Note where you stopped | Note where you stopped | Note where you stopped | Note where you stopped | Plan next week |

Two tips for using it:

* **Fill it on Sunday or Monday morning**, then only adjust it daily. Building a plan from scratch every day is tiring.
* **Leave one afternoon light.** Wednesday above has no meetings so a deep block can run long if you are on a roll.

## Variations: timeboxing and day theming

Time blocking has two close relatives. Pick the one that fits how your work arrives.

| Method | How it works | Best for |
| --- | --- | --- |
| Time blocking | Each block holds a type of work; you choose the task inside it | Most knowledge work |
| Timeboxing | Each task gets its own slot with a hard end, and you stop when the time is up | Tasks that expand to fill any time you give them |
| Day theming | Each day has one theme: Monday for meetings, Tuesday for writing | Founders, freelancers and anyone juggling several roles |

*Harvard Business Review* describes timeboxing as moving tasks off the to do list and onto the calendar, each with its own slot [5]. The difference from time blocking is small in practice: a timebox has a firm stop, a block is a container.

Many people combine methods. A two hour deep block can hold four 25 minute timed rounds with short breaks; our free [Pomodoro timer](/timer/pomodoro) runs that rhythm in your browser, and a [50 minute timer](/timer/50-minutes) suits longer stretches.

## Common time blocking mistakes

* **Planning every minute with no buffer.** The first late meeting wrecks the rest of the day. Leave about a fifth of your day as buffer at first.
* **Blocks named after topics.** "Thesis" invites drifting. "Rewrite the method section intro" gets started.
* **Too many deep blocks.** Truly demanding work tires you fast. Start with one or two deep blocks a day and fill the rest with shallow work on purpose.
* **Treating a broken plan as failure.** Replanning is part of the method. A blocked day that changed four times is still a planned day.
* **Never checking estimates.** Compare planned and real block lengths at the end of each week and adjust next week's template.
* **Blocking time but not attention.** A deep block with your phone on the desk is a shallow block. Put it in another room, mute chats, close the inbox tab.

## Time blocking with ADHD

Time blocking can help with ADHD, and it can also become one more system you feel bad about abandoning. A few adjustments make it friendlier.

Many people with ADHD describe "time blindness": losing track of how long things take and how much time has passed. The research supports a real difficulty here. A 2020 meta analysis of 12 studies found that children with ADHD have trouble perceiving time, most clearly when estimating longer intervals [6]. Most of the evidence is in children, but adults often report the same experience. A visible plan and a visible timer put time outside your head, where you can see it.

Try these changes:

* **Make blocks shorter.** Start with 25 or 30 minute deep blocks instead of 90. You can stack two once a short one feels easy. A plain [25 minute timer](/timer/25-minutes) is enough.
* **Double the buffers.** If transitions are hard, give every switch a 10 minute landing block.
* **Plan only three blocks for the day.** One deep, one shallow, one buffer. Anything else is a bonus.
* **Treat the block as a start time you can move.** If you miss 9:00, start at 9:20. Missing the start time does not cancel the block.
* **Put one easy task first.** A quick win in the first block can make the next one easier to start.
* **Work next to someone.** Many people with ADHD find it easier to start when someone else is working too, a practice called body doubling. Our guide to [how to focus with ADHD](/blog/how-to-focus-with-adhd) covers this and other strategies, and [ADHD paralysis](/blog/adhd-paralysis) covers the days when no plan feels startable.

If time blocking keeps making you feel worse, drop it for a week. A short list and one timer is a perfectly good system.

## Fill your deep blocks with company on Roomie Cafe

A block on a calendar does not start itself. When your deep block arrives, open [Roomie Cafe](/), press start, pick what you are working on, and you see who else is focusing right now and on what. There is no webcam, no microphone and nothing to book. If you want company for a specific block, message a friend the time and both press start then.

When the timer ends you write a line about what you got done. Your history fills a heat calendar with your totals and weekly goals, and there are no streaks, so a day the plan fell apart costs you nothing. Roomie is free on the web and as an [iPhone, iPad and Mac app](/app).

If the blocks are fine and the problem is starting at all, read [how to stop procrastinating](/blog/how-to-stop-procrastinating) next. For ways to run timed rounds inside a block with friends, see [Pomodoro timers with friends](/blog/pomodoro-timer-with-friends).

## FAQ

### What is the time blocking method?

It is a way of planning your day by assigning every working hour to a block with one job, such as deep work, email or a break. You plan the blocks the evening before or in the morning, and redraw them when the day changes.

### What is the difference between time blocking and timeboxing?

Time blocking reserves time for a type of work, and you pick the task inside the block. Timeboxing gives one specific task a fixed slot with a hard end, and you stop when the time is up, finished or not.

### How do I start time blocking?

Put your fixed meetings on the calendar first, then add one deep block at your best time of day, two short blocks for email and admin, and a buffer in the morning and afternoon. Keep that pattern for a week before adding more.

### Does time blocking work for ADHD?

It can, with changes: shorter blocks, more buffers, only three blocks a day, and permission to start late. Some people with ADHD find a rigid schedule makes things worse, so treat it as an experiment.

### How long should a time block be?

Deep blocks usually run 60 to 120 minutes, shallow blocks 20 to 45, and buffers 15 to 30. If you are new to it or have ADHD, start with 25 to 30 minute deep blocks and build up.
