How to use inmycalendar - and why a board works

How to use it, in ten seconds

Everything saves automatically as you go. There is nothing to set up, and no account needed unless you want your board on more than one device.

Most task apps forget the calendar. Most calendars forget the tasks. inmycalendar keeps both in one place: a sticky-note board for what you're doing today, and a week-by-week view of the years around it.

The board

Three columns - to do, in progress, done - side by side on every screen size, phones included. Each task is a single line so a full day fits without scrolling. Type into a column to add straight to it. Drag to reorder, or use the arrows: the top of a column is your highest priority, so ranking costs nothing to express.

Switch the scope to week or month to see everything from that stretch of time in one read-only list; click any line to jump back to the day it belongs to. A column scrolls once it passes ten tasks, so a busy day never pushes the calendar off the screen.

Moving a task, and undoing it

Every task carries a row of controls. The arrows move it up and down its column or left and right between to do, in progress and done. ◎ moves it to today in one tap, and only appears when the task is not already on today - on today's board it would do nothing, so it is not there. 📅 opens a date picker to send it to any other day. × deletes it.

Almost everything can be undone. Delete a task, move one to today, sweep a week forward, and a bar appears offering to put it back. It stays available for about 45 seconds, so a mis-tap is never final. Undo restores the task to the exact column and position it came from, not just to the day.

A task can be more than one line. Enter adds the task; Shift+Enter starts a new line inside it, the same convention every chat box uses. Pasting several lines keeps them as one task rather than silently mangling them into a single run-on line.

Picking up where you left off

Open today's board and anything still unfinished from any earlier day is offered at the top: how many tasks, how many days, and how far back the oldest one goes. Move all to today brings the lot forward in one action, keeping their order, and the whole sweep is a single undo.

It looks at every earlier day, not just yesterday. Yesterday is the one case where you did not need reminding - you were here. Come back after a week away and it is the tasks that have been open longest that matter.

Dismiss it and it stays dismissed for the rest of the day.

The calendar

Years sit side by side, laid out by week rather than by month, so a long stretch of time reads at a glance. The arrows in the calendar's own header move the whole window a year at a time. Colour a day and the whole cell takes that colour.

Four things can mark a day and they never clash: the cell colour is your own category, a coloured line underneath is a public holiday (red for national, blue for regional), a ring is today, and a small dot means that day has tasks. Hovering a day shows the holiday name, your note, and the tasks on it.

Day colours

Colour a day and the whole cell takes that colour, so a year of leave, travel or deadlines reads at a glance. The panel on the right lists your colours with a count beside each one, so you can see how many days you have marked without counting them yourself.

You can add a colour, rename one by clicking its name, delete one, and drag a row to reorder the list. Deleting a colour that is in use tells you how many days it will clear first. Hide collapses every day colour on the calendar without deleting anything, which is useful when you want a clean screenshot of just the holidays - the days still remember their colour and come back when you show them again.

Marking several days at once. Press Select days, then click a day and click another to take everything between them, or drag across a run of days. Ctrl-click (Cmd on a Mac) adds or removes single days. Then pick a colour and the whole selection takes it in one go, which is how a two-week holiday gets marked without fourteen clicks.

How weeks are numbered

Everyone agrees a year has weeks. Nobody agrees which one is week 1. Four rules are in real use worldwide, so you pick the one your organisation follows, under Calendar setup.

Why Thursday? It is not a magic day. Thursday is the fourth day of a week that starts on Monday, so "the week containing the first Thursday" and "the first week with 4+ days" are two ways of saying the same thing - but only for a Monday start. Start your week on Sunday and the fourth day is Wednesday, and the two rules genuinely part company. That is why both are offered rather than one being quietly applied under the other's name.

Under every rule except "first week fully inside the new year", the last days of December often belong to the next year's week 1. Under all four, the first days of January can belong to the previous year's final week. That is correct, not a mistake. With weeks starting Sunday, week 1 of 2026 begins on Sunday 28 December 2025 under the Thursday rule, and on Sunday 4 January 2026 under the majority rule.

You choose which day your week starts on separately, and all seven days are available - Monday for most of the world, Sunday across the Americas and much of Asia, Saturday across much of the Middle East. The two settings work together: the start day decides where each week begins, and the rule decides which one is first.

If you just want the number without opening the calendar, what week is it gives today's under both the ISO and US systems, and there are reference tables for every week of 2026, 2027 and the years either side. Why the two systems disagree is set out at ISO 8601 week numbers.

Keyboard

Finding something later

Press / anywhere, or click the magnifier by the date, to search every task and day note you have written. Click a result to jump straight to that day.

Repeating a task

Hover a task and click the ↻ button to cycle it through every day, every week, every month and off. Repeats appear as ordinary tasks on the days they fall, so you can move, rename or delete any single one without touching the rest.

Day notes

Every day can carry a short note - what happened, a decision, anything worth remembering. Write it under the board, or open the day from the calendar. Done closes it, Cancel puts back what was there before, and Clear empties it. Notes show when you hover a day, and they come out in the CSV export.

Countdowns

Add any date that matters and it counts the days since, or until, it happens. Click a countdown's name to correct it, and switch between days, weeks, months and years with the dropdown beside it.

Where your data lives

By default, in this browser and nowhere else. No account is needed and nothing is uploaded.

Sign in (top right) if you want the same board on your laptop, phone and tablet. It is optional - it uses Google, Microsoft, GitHub or a one-time link sent to your email, and the app works exactly the same either way.

Either way you can take your data with you. Backup saves a JSON file, Restore reads one back, and Export tasks writes a CSV that includes your day notes and day colours. All three are in the footer.

What a Kanban board is

Kanban means “signboard” in Japanese. Toyota engineer Taiichi Ohno built the system in the late 1940s to control car production: cards moved across a board to signal what to build next, so nobody made parts that weren’t needed yet. Software teams borrowed it decades later, and it is now the default way most teams track work.

The idea is deliberately simple. Work moves left to right through columns, and you can see the whole flow at once:

The one rule that matters: limit how much sits in “In progress”. Most people’s problem isn’t too few tasks - it’s five half-finished ones. Toyota’s insight was that starting less finishes more.

Using it with a team

The same three columns work for a team as for one person. A team typically agrees a cap on the middle column - say two items per person - and when it is full, nobody starts anything new until something is finished. Whatever has been sitting in “In progress” longest is usually the thing worth talking about at a stand-up.
