Free time-block day planner

Plan your day in blocks, let the planner find the next free slot with buffers, see how much time is really left, and export the plan to any calendar.

Your blocks

    No blocks yet. Add your fixed points first, like meetings, then fill the gaps.

    Nothing is saved or sent anywhere. Export before you close the page.

    How to use it

    1. Set when your day starts and ends, and how much buffer you want between blocks. Ten minutes is a good default.
    2. Add your fixed points first, like meetings and appointments, using Add at this time.
    3. Add everything else with Add in next free slot. The planner places each block after the last one that fits, buffers included.
    4. Check the line under the list. Free time left shows how much of the day isn’t planned yet. If it’s zero, the plan is too full.
    5. Download the calendar file, or print the day.

    The list is the real plan, and you can operate it fully with a keyboard. The timeline beside it is a picture of the same blocks. A block that overlaps another, or falls outside your day, is labeled in the list.

    Plan a day you can actually keep

    • Plan about two-thirds of your hours. Leave the rest empty. It soaks up interruptions, overruns and the task you forgot.
    • Put the hardest block where your energy is. For many people that’s mid-morning. For others it’s late afternoon. Plan around your real energy, not an ideal one.
    • Use typed blocks. Focus, admin, meeting, break and personal blocks have their own colors, so you can see when the whole day is meetings with no focus time.
    • Give breaks a block. A break that’s on the plan actually happens.

    If rigid schedules don’t work for you

    Time blocking doesn’t need to be hour-by-hour. Some people block in zones instead, like “deep work until lunch” and “admin after 3”, and use the planner only to check that the zones fit. When a block slips, move it to the next free slot instead of rebuilding the day.

    Time blocks in Thendoo

    In the Thendoo app you drag tasks onto your Today timeline, between your Google Calendar meetings. You can also send your time blocks to a separate “Thendoo” calendar in Google, so the people you work with can see when you’re busy.

    Questions

    What is time blocking?

    Giving each piece of work its own slot on your calendar, instead of keeping a to-do list and hoping the time appears. It turns "write the report" into "write the report, 9:00 to 9:50", which makes it much easier to start and to say no to other things.

    What does "Add in next free slot" do?

    It looks for the earliest gap after now, inside your working day, where the block fits with your chosen buffer before and after. It's the quickest way to plan without dragging blocks around. If nothing fits, it tells you instead of overbooking the day.

    Why add buffers between blocks?

    Because things run over, and switching between tasks takes time. A 10-minute buffer between blocks keeps one late meeting from pushing the whole day back. People also tend to underestimate how long tasks take, so leave room.

    Can I put the plan in my calendar?

    Yes. Download the .ics file and open it with Google Calendar, Apple Calendar or Outlook to add today's blocks as events. Nothing is saved on this page, so export or print before you close it.
