Time blocking in Google Calendar: a step-by-step guide

Time blocking means giving each task a start time and a length instead of keeping a list and hoping. Google Calendar is where most people try it first, for good reasons: it is free, it already holds the meetings you have to plan around, it syncs between your phone and your computer, and on a work account a block tells colleagues you are busy before they book over it.

It is not a task manager, though. Time blocking in it is the habit of turning the few tasks that matter today into appointments with yourself, and the setup below makes that habit take minutes.

1. 1.
   Create a calendar for your blocks. On a computer, open Google Calendar, click the plus next to Other calendars and choose Create new calendar. Call it "Blocks". You can then hide every block with one click and give blocks their own alerts. (On a work account, read the note on busy time below first.)
2. 2.
   Choose one color per type of work. Four is plenty: blue for deep work, green for meetings, yellow for admin and messages, purple for personal. At a glance, the week then shows whether it holds any deep work at all.
3. 3.
   Set the default event length. In Settings, under Event settings, set Default duration to your usual block, such as 60 minutes, so every block starts at the right size.
4. 4.
   Give the blocks calendar its own alert. In that calendar's settings, add a notification at the start time or 5 minutes before. The alert is what tells you to switch to the next block.
5. 5.
   Show your tasks. Under My calendars, tick Tasks. Any Google Tasks task with a date now appears on the grid next to your events.

1. 1.
   Open the day or week view the evening before or first thing in the morning (press d or w on a computer). Your meetings are already there; what is left is the time you actually have.
2. 2.
   Pick one to three tasks that matter today. Everything else stays on your list, not on the calendar.
3. 3.
   Drag across an empty slot to create a block, or press c. Name it with a verb and an object, "Draft section 2 of the proposal" rather than "Proposal", put it on the Blocks calendar and give it its color.
4. 4.
   Size each block to your estimate plus a quarter: a one-hour task gets 75 minutes. Most people underestimate.
5. 5.
   Put the hardest block in your best hours, which for most people is the first half of the morning.
6. 6.
   Batch the small stuff into one or two blocks of 30 minutes: email, messages, forms.
7. 7.
   Leave about 20 percent of the day empty for whatever runs over.
8. 8.
   Make routines, like a daily email block or a Friday review, recurring events.
9. 9.
   When a block does not happen, drag it to the next free slot or to tomorrow right away, so the calendar keeps telling the truth.

Block the work that matters and leave the rest on the list. A calendar with every task on it is full by Monday at noon.

Google Tasks is built into Google Calendar, and since an update in November 2025 a task can take up time on the grid instead of only sitting at the top of the day. That is the closest Google gets to a time-blocked to-do list: a block you can tick off.

1. 1.
   In the day or week view, click an empty slot and switch the new item from Event to Task.
2. 2.
   Type the task, then set the date, the start time and how long you plan to spend on it. Add a description, or a deadline if it has one.
3. 3.
   Save. The task shows on the calendar as a block and in your task list, and it keeps reminding you until you mark it done.
4. 4.
   To give a task you already have a slot, open it and choose Add time.

Three limits, from Google's own help page: repeating tasks cannot have an end time, so routines work better as recurring events; a task with subtasks cannot repeat; and a task without a time sends its reminder at 9 a.m. Beyond that, Google Tasks is a plain list with no priorities, labels or goals.

If your Google account comes from work or school, Google Calendar has features made for this. Which ones you get depends on your organization's plan.

• •Focus time is a type of block you create from the day or week view on a computer. It can decline new meetings, or all meetings, that land on it, and mute Google Chat while it lasts. Google lists it for the Business Standard and Plus, Enterprise, Education and Nonprofits plans (help page), so not for personal Gmail accounts or Business Starter.
• •Working hours show anyone who tries to book you outside them that you are not available. You set them once, from a computer, in Settings.
• •Busy time comes from your main calendar. When colleagues look for a time to meet, Google generally checks your primary calendar, not the extra ones you created. On a work account, put blocks that must stay protected on your main calendar, or make them Focus time.

On a personal account, an ordinary event set to Busy does the same job, minus the automatic declines.

A realistic day with one big piece of work, a team meeting and a client call: six hours planned, lunch on the calendar and an hour left empty.

Google Calendar is a good place to keep blocks and a weak place to plan them. After a few weeks, most people hit the same four limits.

• •Tasks and events still live apart. Tasks can now take time on the grid, but the list behind them has no priorities or goals, so deciding what deserves a block still happens in your head.
• •Re-planning is dragging. When a meeting moves or a block runs over, every block after it has to be moved by hand. On a phone that is slow enough that most people stop, and the calendar stops matching the day.
• •Undone work stays behind. A block that did not happen sits in the past, and an unfinished task waits in a pending list until you give it a new slot.
• •Free time is something you count. The calendar shows what is booked, not how much room is left for the three tasks you still have.

Superhive is a daily planner built around those gaps. Give a task a length and on the day view it lands as a block in the free time around your events, so you see whether the day fits before it starts. With Pro, it imports your Google Calendar events and writes scheduled tasks back to Google Calendar as blocks as long as the task, so Google Calendar still shows your whole day. At the end of the day, the daily shutdown rolls whatever did not get done to tomorrow instead of leaving it in the past.
