Time Blocking: How to Put Your Tasks on Your Calendar

At 8 am the calendar looks perfect: every task in its own neat block. By 11 a meeting has moved, the first task ran long, and the rest of the plan has quietly stopped being true.

That is how time blocking usually fails, and it is not a willpower problem. Here is how to block your day around the meetings you already have, and what to do when a task runs over.

What is time blocking?

Time blocking means giving each important task its own slot on your calendar. A to-do list says what you want to get done. A blocked calendar says when you will do it, and how much of the day it may take.

The writer Cal Newport wrote in 2013 that he spent ten to twenty minutes every evening building the next day's schedule, and estimated that a 40-hour time-blocked week produces as much as a week of 60 hours or more without structure. That is his estimate, not a measured result.

Why it can work is better studied. Deciding in advance when and where you will act is called an implementation intention, and a meta-analysis of 94 tests found these plans had a medium to large effect on reaching goals. A calendar block is one way to make that kind of plan: it settles in advance when you will start.

Why does my time-blocked day fall apart by noon?

Two things tend to break it, and neither is about discipline.

Even our worst case tends to be hopeful. In a classic study of the planning fallacy, students guessed how long their thesis would take if everything went as badly as it could. On average, that worst-case guess was about 49 days, and they took about 56. Blocks drawn at 8 am carry the same optimism, which is what a buffer is for.

Meetings land on the hours you meant to protect. Microsoft looked at when people meet, across Microsoft 365.

So the answer is not to try harder. Block less, build the plan around the meetings already there, and decide in advance what happens when something runs over.

How do I see my tasks and my meetings in one place?

Time blocking gets hard when your tasks live in one app and your meetings in another. The usual workaround is putting tasks on Google Calendar as events, by hand. A calendar and to-do list app in one removes the copying.

In Ranya, every task with a date is on your calendar automatically. Then add the calendar your meetings live in: Google Calendar, Outlook or iCloud, from a link you copy out of its settings. In the app's words, "Its events show up on your calendar, read only." Ranya never writes back to them, and checks them for changes about every 15 minutes.

Some meetings are on your calendar but not in your day. Open one and choose Hide this event, or Hide all in this series. It leaves your calendar, your day and what Ranya reads out to you. See everything tasks and the calendar can do.

How much of the day should I block?

Less than you think. A plan that fills every hour has no room for the overrun you now know is coming.

• Block your few, not your list. Give a time to the two or three things that would make today count, and let small tasks fill the gaps.
• Leave a buffer after each block. Fifteen or thirty empty minutes is where an overrun lands.
• Leave the end of the day open. The last hour catches whatever slipped, so it moves within today instead of into tomorrow.

If your days are mostly meetings, one protected block beats six that all slip.

How Ranya handles time blocking, and why it never moves your day for you

Ranya is built on one rule here: it suggests, you decide. Ask on a call, "find me two hours for the tax return this week", and she checks your tasks and your other calendars, then offers one open slot, the best first. Say yes and it is on your calendar. Ask for another time and she offers the next. Say no and nothing changes.

In the app, the same suggestion is the first row of a task's Quick dates. One tap places it, and the arrow beside it shows another time.

• Only you know what a free hour is for, so a slot stays a suggestion until you say yes.
• Other calendars stay read only, so nothing Ranya does can touch meetings other people rely on.
• Keep on calendar is opt in, per task. Once it is on, a late one-off task stays listed until you finish or dismiss it, however long that takes. A task that quietly vanished after a few days would break the one promise the switch makes.
• Focus warns; it does not rearrange. When a meeting from a calendar you added is about to cut into a block, the session says so and leaves the block alone.

How to time block your day in Ranya, step by step

1. Add your other calendar

   In Calendar, choose Add a calendar beside Calendars: it is the + next to the heading. Pick Google Calendar, Outlook or Apple Calendar (iCloud), and paste the link it shows you how to find.

2. Hide the meetings you never go to

   Open one and choose Hide this event, or say "hide the all-hands from my calendar".

3. Choose today's few first

   Open Plan today in Focus. Its Suggested list gathers what is due today, the late tasks you chose to keep on the calendar, what is pinned, your inbox and the habits today still owes. Pick two or three, the way how to plan your day describes.

4. Give each one a time

   Set it on the task, take the suggestion at the top of its Quick dates, or ask for time on a call. Say yes to the slot she offers.

5. Leave a buffer after each block

   Fifteen or thirty minutes, and keep the last hour of the day open.

6. Start Focus on the first block

   Press ⌘⇧FCommand Shift F, or use the + that appears beside Dashboard in the sidebar (Start a focus session). If a meeting from a calendar you added is about to cut in, the session says so. To keep the block clear of everything else, read how to stop getting distracted.

7. When something runs over, move the next thing

   Give the next task a later time, or say "Move the landlord reply to 5." For the task that must not drop out of sight, turn on Keep on calendar.

What happens to a task I didn't get to?

A dated task you did not finish stays on the day it was due, drawn faded. It does not follow you to today, and Plan today does not chase it, so last week's leftovers never pile up on this morning. To pick it up again, search for it or give it a new date.

For the few that must stay in front of you, like renewing a passport before a trip, turn on Keep on calendar in the task's date options. If it is still not done when its day passes, it joins the overdue count at the top of today and sits under Overdue in Plan today, until you tick it or dismiss it. For a repeating task, a missed one stays listed until the next one is due. It is off unless you turn it on, task by task, so today never fills up with everything you let slide.

For tasks that come back every week or month, read how to remember to do things.
