DayBlock - Time Blocking Day Planner
DayBlock is a day planner built on time blocking: instead of a long to-do list, every task gets a place on a timeline, so you can see at a glance what the day really holds. Blocks are coloured and can carry an icon, which makes it easy to tell work, study, exercise and breaks apart.
You can drag a block to move it and pull its bottom edge to change its length, with times snapping to five-minute steps. Ideas that don't have a time yet go into the Inbox, repeated activities can be set to recur, and routines like a morning or evening sequence can be dropped onto any day in one go.
The calm dark design keeps the focus on the plan itself. It works well for students, freelancers, people working from home and anyone who finds an open-ended list overwhelming.
The app runs entirely in your browser. What you enter is saved only on this device.
How to use DayBlock
- Add a block. On the Timeline tab tap +, type a task name and optional memo, choose the start time and a duration (15 minutes to 2 hours or custom), pick a colour and icon, then tap New Task.
- Adjust it on the timeline. Drag a block up or down to move it, or drag its bottom edge to make it longer or shorter. A red line marks the current time.
- Capture ideas in the Inbox. Open the Inbox tab and type a task into the quick-add field. When you know when to do it, tap the calendar icon next to it to schedule it onto the timeline.
- Set repeats. In a task's Repeat section choose daily, weekly, monthly or yearly, with specific weekdays or a custom interval. Repeated blocks then appear on the matching days.
- Save routines. On the Routines tab create a sequence such as a morning routine and apply it to a day with one tap.
- Check the week and tick things off. Use the week icon at the top to see seven days side by side, mark blocks complete with their circle, and add subtasks for checklists inside a block. The search icon finds tasks by title or memo.

How time blocking works
From lists to calendars
A to-do list tells you what to do, but not when, and it rarely shows whether everything actually fits in the day. Time blocking turns each task into an appointment with yourself. The moment you try to place eight hours of work into a five-hour gap, the conflict becomes visible and you can decide what to postpone — before the day is over rather than after.
A simple daily routine
Plan tomorrow at the end of today, or first thing in the morning, in about ten minutes. Start with fixed commitments such as meetings or classes, then add your most important task in the time of day when you concentrate best. Fill the rest with smaller tasks, and leave gaps. Many people group similar small jobs — emails, calls, errands — into a single block, sometimes called task batching.
Plan for reality
Tasks usually take longer than expected; this tendency is known as the planning fallacy. Add a buffer of 10 to 20 percent, put short breaks between demanding blocks, and keep at least one flexible block in the afternoon for things that overrun. When the plan breaks — and it will — don't abandon it: drag the remaining blocks to new times. Re-planning is part of the method, not a sign of failure.
Make it stick
Colour by category so you can see the balance of your day: if everything is the work colour, rest is missing. Recurring blocks and routines handle habits like exercise, reading or a weekly review automatically. At the end of the week, glance over the weekly view to see where your time actually went and adjust next week's plan accordingly. Time blocking is especially helpful for people who find unstructured time hard to start, because the next step is always written on the timeline.
Frequently asked questions
Is DayBlock free in the browser?
Yes. The timeline, inbox, repeats, routines, weekly view and subtasks all work without an account.
Where are my tasks stored?
Only in this browser on this device (IndexedDB). Nothing is uploaded. Clearing site data for this website or using a private window deletes your plan.
Will I get reminders when a block starts?
No. Browsers cannot deliver reminders when the page is closed, so the web version has no notifications. Keep the page open to see the current-time line.
Can I sync with my phone or calendar?
Not at the moment. The web version and the phone app keep separate data, and there is no calendar import or export.
What happens to unfinished tasks?
They stay where they are. Drag them to a later time, or edit them to move them to another day.
How is the web version different from the phone app?
Planning works the same way. The iPhone and Android app offers an optional ad-free upgrade; purchases are not available on the web.
Limitations of the web version
- No notifications or reminders on the web
- Data is stored only in this browser and is not synced
- Drag gestures work best with a mouse or touch screen; small screens show fewer hours at once
- In-app purchases are not offered on the web
