Time blocking

What is time blocking? Meaning and definition

Time blocking means dividing your day into stretches of time and giving each stretch a specific activity, so that your calendar says what you'll do and when. It's also called calendar blocking or block scheduling, and each stretch is a time block.

Your Monday has a budget review at 09:30, figures to revise afterwards, a contractor's quote to answer and a physio appointment at 15:15, along with the exercises you've already put off twice. On a list, the figures and the exercises wait for a quiet moment, and the day fills up before one comes. On a blocked day, the figures start at 10:45, and you can see that before the first message arrives.

A time block is a plan rather than a promise, so you can move it when the day changes. The point is a day that's a little less chaotic, not a perfect one. A block can hold more than work, too, such as lunch or the trip to the physio.

When does time blocking work well?

• When important work keeps losing to whatever's loudest. Messages arrive by themselves, and the figures don't. Giving them a place means they're already on the day when the messages start.
• When your day has fixed points in it. A list can hide the fact that you have three free hours and nine hours of hopes. Once the review and the physio are on the day, you can see what really fits.
• When deciding what's next keeps wearing you down. You decide once, at a calm moment, so at 13:00 you can simply look.

It can suit a day of constant interruptions less well, and there's a smaller version further down.

How to do time blocking

You can do this on paper, with the hours written down one side.

1. Put down what's already fixed. The review and the physio go on first, along with the time it takes to get to them.
2. Choose what you'd like from today. Keep it short. The figures are in, and so are the things that keep you going, like lunch.
3. Give the hardest job your best stretch. That's usually the longest gap, at the time of day you think most clearly.
4. Place the rest, and leave some of the day empty. The empty part is what lets the plan survive a meeting that runs long.
5. When the day changes, redraw from now. Leave the morning as it was, and rearrange only what's still ahead. Nothing you missed needs making up.

How long should a time block be? A worked day

Start from how long the job took last time, rather than how long it ought to take. Most of us picture the version where nothing goes wrong. Then look at what kind of job it is. These are starting points, and your own will soon replace them.

• Jobs you load into your head first often suit 60 to 120 minutes, and then a break.
• Small, clear jobs can share one block of 30 to 45 minutes.
• Fixed things get their real length, plus the time around them.

Here's the Monday, with the reason for each size.

Then the review runs half an hour over, and the first block is in trouble by 10:45. You keep a short debrief, let the stretch go, and slide the figures, lunch and the second block along by ten minutes. The open stretch shrinks, and the physio doesn't move. That's what the sizes were for: one block went wrong, and the afternoon held.

Time blocking is usually described as a way to protect work. Our own view goes further: a plan that holds only tasks describes a day you won't actually have. Once lunch and the gaps between things have a place, you can see how much room the figures really have.

What to do when a block goes wrong

A blocked day can feel awful when the real day doesn't match it, as if you'd failed a test you set yourself. Most days won't match, and that's all right. A day that went half to plan may still have been calmer than one with no plan at all, and that's what you were after.

So give yourself some grace. When a block goes wrong, it says more about the plan than about you, and what helps depends on what happened.

• It ran over, and the next thing can move. If it's going well, keep going, and slide the next block into the open stretch.
• It ran over, and the next thing can't move. The figures are still going at 15:00, and the physio won't wait. Write one line on where you stopped, and give the rest a new block.
• Something urgent took its place. Move the block rather than squeezing it into what's left. If nothing's free, choose what comes off today.
• You sat down and couldn't start. The block may be too big or too vague. Rename it after the first step, such as "Check the travel costs", or swap it with something lighter.
• The whole day has gone. Keep the fixed things and one other thing, and let the rest go. Tomorrow gets its own plan.

If your days are mostly interruptions, because of your job or someone you care for, try blocking just one thing, or make a block for the reactive work itself, and leave the rest open. On some days a plain list may suit you better, and that's a perfectly good way to run a day.

How to time block in Xale

Xale's Day puts your meetings, tasks, habits and the rest of your life on one timeline. Each example ends with how to do the same thing in other apps.

Block a day that holds more than tasks

Try this when you have a list and a few fixed times, and you'd like to see whether it all fits.

1. Open Day. Your meetings are already there if you've subscribed a calendar. For anything else that's fixed, drag Quick block from the tray and give it a title, such as "Physio".
2. Drag your hardest task from the tray to your best stretch. If it needs two sittings, make it two tasks, such as "Figures: first pass" and "Figures: finish and send".
3. Drag a block's bottom edge to the size you chose. On a phone, tap + Plan on free time, then Place.
4. Drag Activity from the tray for the things that keep you going. Pick the closest item on your list, title it "Lunch", and press Add to plan.
5. Leave what doesn't fit in the tray, along with at least one empty stretch on the day. You're giving the day some shape, and it doesn't have to go exactly like this.

With Xale Pro, a block's menu also has Send to Google Calendar, if you'd like it on your calendar too.

In other apps: add events to Google Calendar or Outlook, and mark the ones you're protecting as busy. Sunsama and Structured also suit this.

Put named buffer time between your time blocks

Try this when one block runs straight into the next, and you arrive at the figures still thinking about the meeting.

1. In Day, drag Transition from the tray to the end of the budget review, and choose wind-down.
2. Pick a title that says what the time is for, such as Debrief, Walk or Drink. A named gap is easier to keep than an empty one.
3. Drag another Transition to just before the first block of figures, choose lead-in, and pick Stretch.
4. Set how long each one runs, from five to sixty minutes.
5. Drag one more to just before the physio, choose lead-in, and write your own title, such as "Pack up and leave".

In other apps: add short, named events on either side of a meeting or block.

Time block a habit that keeps getting moved

Try this when something you care about keeps sliding, and a fixed weekly slot hasn't held.

1. Open Habits, press New habit, and give it a plain name, such as "Physio exercises".
2. Set how often to Per week, and choose a number you'd be happy with, such as three. The days stay open.
3. In Description, write what counts, such as "The exercises on the sheet. Half a set counts too."
4. Each day, it appears beside your day as a suggestion. On a day it fits, drag it from the tray to a time.
5. If the week fills up and you miss it, nothing happens. You can place it again when there's room.

In other apps: keep a repeating reminder and move it to whichever day suits, or write "exercises, three times" at the top of the week on paper.

Follow your time blocks, and move one when the day shifts

Try this once the day has started, and you'd like to see only the block you're in.

1. Open Now. It shows the current block, the time left, what's up next and the rest of today.
2. Stay with the block. Now doesn't nag when you run over, so whether to keep going is up to you.
3. If something else comes to mind, press Add task and go back.
4. If the block can't happen now, open the menu beside Dismiss and move it later, to this evening or to tomorrow. A task's block can also go back to the tray.
5. Press Mark done when you've finished, or Dismiss if you're skipping it. A dismissed block stays on your day, and skipping one is a normal part of using a plan.

In other apps: move the event in your calendar, and keep a full-screen timer beside you.

How to get better at time blocking

• Compare the plan with what happened. For a week, jot the real time beside each block. It isn't a score, and you may find a rule of your own, such as "budget work takes half as long again".
• Notice what keeps moving. If the exercises move every week, the time may be wrong, or the number of times.
• Keep a rough shape for your usual week. The fixed things and lunch, already in place, give you your own time block template, so Monday doesn't start from blank.
• Block less if you're moving nearly everything. One or two blocks that hold can tell you more than a full day that doesn't. Add more once those feel easy.

Paste these into Claude, ChatGPT or Gemini, and fill in the brackets.

Turn a list into a blocked day

These things are fixed today: [commitments and times]. I'd like to fit in: [tasks, and how long each took last time if I know]. I also want room for [lunch, exercise, getting from place to place]. Draft a time-blocked day that leaves at least [one hour] open. Then tell me what you left out, and why.

Redraw the rest of today

It's [time], and my plan has slipped because [what happened]. These things can't move: [commitments]. Still on the plan: [blocks]. Redraw my day from now, without adding anything new. List what moves to another day, and tell me the one thing most worth keeping.

Time blocking: common questions

What's the difference between time blocking and timeboxing? Time blocking gives something a place in your day. Timeboxing sets a limit on it and decides in advance what happens when the time runs out. You can use both on the same job.

Do I need a time-block planner or template? No. A time-block planner is a page with the day's hours laid out and room for notes. A sheet with the hours down the left does the same job.

Who came up with time blocking? Nobody in particular, since people have long planned their days by the hour. The writer Cal Newport did much to make the term familiar.

What if I can't stick to my time blocks? Few days go exactly to plan, so you're not doing it wrong. Try fewer blocks and more open time, and move what didn't happen without any fuss. The aim is a day with a little less chaos, rather than a perfect one.

Does time blocking work with ADHD? It varies. Some people with ADHD find that seeing the day helps, and others find a tight plan hard to keep. Shorter blocks and generous gaps are worth trying.

What's another word for time blocking? Calendar blocking and block scheduling mean the same thing here. In schools, block scheduling also means something different: a timetable of fewer, longer classes.
