Timeblocking: how to block your day – a guide in 6 steps

You have a to-do list with 23 items, the day is half over, and two of them are done. Sound familiar? Then it is worth taking a look at timeblocking – a method that turns a list into a day.

What is timeblocking?

With timeblocking, every task gets a fixed place in the day. Instead of “write the proposal” somewhere on a list, your calendar says: 9:00 to 10:30 – write the proposal. Then comes the next block, for example 10:30 to 11:00 – emails. The day becomes a row of blocks, one after the other.

That sounds simple, but it fundamentally changes two things. First, you immediately see whether your day is long enough at all: eight hours of tasks do not fit into five hours of time, no matter how motivated you are. Second, you do not have to constantly decide what comes next. You made the decision once – in the morning or the evening before.

Why timeblocking helps especially with ADHD

Many people with ADHD describe two hurdles in everyday life: starting and the sense of time. A list helps little with either. It shows everything at once, everything seems equally important, and how long something takes is written nowhere.

Blocks, on the other hand, make time visible. A block as big as its duration shows you at a glance: this is a big thing, this one a small one. And there is always a clear answer to the question that costs the most energy in your head: what is due now? More on why the sense of time sometimes goes on strike in the article on time blindness.

Guide: timeblocking in 6 steps

1. Collect what is coming up

Write down everything that comes to mind for tomorrow – unordered, without judging. Out of your head, into a list. This list is only the raw material.

2. Enter the fixed appointments

Doctor’s appointment, meeting, picking up the kids: whatever has a fixed time goes into the day first. That way you see how much free time is really left. Often it is less than you think.

3. Choose three main things

From the list, pick at most three things that really matter tomorrow. Only these get their own big blocks. Why three are enough is explained in the article on the art of the short list.

4. Estimate honestly – and add buffer

How long does the proposal really take? Not in the best case, but on a normal day with interruptions. Better add a quarter. And leave air between blocks: 10 to 15 minutes to breathe, get water, switch over.

5. Plan only 60 to 70 percent

A day that is 100 percent planned has already failed by 10 am. Something always comes up. So deliberately plan gaps. The free time is not a loss, it is your cushion.

6. Small stuff in a catch-all block

Emails, calls, transfers: small tasks do not get their own block, they go together into a “small-stuff block” of 30 minutes. That way they do not fray your whole day.

An example day

This is what a blocked day can look like – with three main things, breaks and air:

• 08:00 Coffee and arriving (morning routine)
• 09:00 Write the proposal (main thing 1)
• 10:30 Break, step outside
• 10:45 Small-stuff block: emails, calls
• 11:30 Sort receipts (main thing 2)
• 12:30 Lunch and a walk
• 14:00 Prepare the presentation (main thing 3)
• 15:30 Buffer – or bonus
• 17:00 Wrap up the day, look at tomorrow

Notice: between 15:30 and 17:00 nothing fixed is planned. That is exactly what makes the plan realistic. If the day goes well, you pick something from the list here. If it goes badly, the buffer absorbs the delay.

When a block does not work out

It will not work out – at least not always. That is not a failure of the method, it is normal. A plan is a suggestion to yourself, not a contract. When a block falls apart, you have three options:

1. Move it: later in the day, if there is still buffer.
2. Postpone it: to tomorrow or another day – with a fixed place, so it does not get lost.
3. Drop it: some things are no longer important the next day. That is a decision too.

What matters is a quick tidy-up in the evening. A ten-minute day wrap-up makes sure unfinished things get a new place instead of floating along as a guilty conscience.

Paper, calendar or app?

Timeblocking works with anything that can show time: a sheet of paper with hour lines, a wall calendar, a calendar app or a day planner. Paper is calm and tangible. An app can calculate repetitions, move blocks without you having to erase anything, and show you where you are in the day. What matters in an app I have summed up in nine criteria for planner apps.

Whatever you use: start small. Block only tomorrow morning. If that works, add the afternoon. After a week you will know whether the method suits you – and which blocks always take longer than you thought.

Five typical timeblocking mistakes

• Blocks that are too small: if you plan every quarter of an hour, you spend more time re-planning than working. Blocks under 30 minutes are only worth it for routines and small stuff.
• No breaks: a day without break blocks lasts until lunchtime. Breaks belong in the plan like appointments.
• Everything equally important: if every block is a main thing, none is. Mark the three that really count today.
• Defending the plan: a plan that is no longer right at 11 am may be re-sorted. Five minutes of re-planning are better than a day ticked off only in your head.
• No wrap-up: without a quick look in the evening, leftovers drift invisibly into the next day.

Plan blocks by energy

Not every hour is the same. Many people have the clearest head in the morning, others only get going in the afternoon. Watch for a few days when thinking work comes easily to you, and put the hardest main thing exactly there. Routine tasks, emails and tidying fit into the dips – for example right after lunch. That way you work with your energy instead of against it.

A good trick for sluggish days: start with a small block that is sure to work. The first tick gives momentum for the next.

Timeblocking with DayBlock

DayBlock is built for exactly this method. You type “Write proposal 9 am 90 min” into one line, and the block is in your day – as big as it takes. A yellow block shows you what is due now. With ▶ you start it, and a clock runs along. Moving works by dragging, and unfinished things move to tomorrow with one tap in the evening. And because DayBlock remembers when you really finish things, over time you see which blocks regularly take longer than planned for you.

Summary

Timeblocking is not a miracle weapon, but an honest mirror: it shows you what fits into your day and what does not. Instead of being crushed by a list, you go block by block. And in the evening you see what you got done – not just what is still missing.
