Calendar activities

An activity is a fixed entry in the calendar: a meeting, a workout, an appointment. Unlike a task, it has a start and an end time and nothing to check off. Activities can belong to an area, which gives them its color.

An activity happens once, or every week on the same weekday and at the same time, from its first day on. Activities are meant to fit within one day: agents can't create one that runs past midnight, and a change can't move one past it.

Add an activity

1. Open quick add: press C. On Today, when the day already has activities, the + on the Schedule group opens it in activity mode directly.
2. Switch to Activity at the top right of the dialog.
3. Type the title with the day, time, length and repetition, for example Climbing with Tomek friday 18:00 for 2h every week.
4. Check the chips below the title and adjust them if needed:
   • When: the start day and time. A time typed in the title takes precedence over this chip. A day alone isn't enough: with no time anywhere, the activity starts now, and the summary line says Starts now; a day picked here without a time starts at 00:00. Quick add opened for a day, from a click on a day in the calendar, say, fills this chip in with that day instead: see Quick add.
   • The length: 15, 30, 45, 60, 90, 120 or 180 minutes. The default is 60 minutes.
   • Does not repeat or Every week.
   • The area, in the chip at the top left.
5. Select Add to calendar, or press Enter.

Quick add reads for 45m, for 1.5 hours and for 2h as the length, and every week, weekly or each week as a weekly repetition. See Quick add.

Where activities show

A click on an activity in any of these views opens it: see Change or remove an activity.

Activities and the auto-planner

The auto-planner treats activities as busy time. It keeps each activity, plus 10 minutes before and after it, free of focus blocks, and plans tasks only in the gaps that remain inside the work hours. See The auto-planner.

Change or remove an activity

1. Click the activity in Today, Upcoming or the Calendar. A dialog opens with the day that was clicked.
2. Change what's needed:
   • the title;
   • the area, in the chip at the top left;
   • the day and start time, in the chip with the date;
   • the length: 15, 30, 45, 60, 90, 120 or 180 minutes, or the activity's own length when it's another one;
   • Every week or Does not repeat.
3. Select Save, or press Enter in the title.

The line above the buttons sums up the result. A weekly activity changes every week, and the line adds Changes apply to every week:

• moved to another day, the whole series moves to that weekday, by as many days;
• switched to Does not repeat, it stays only on the day in the date chip, and the line warns The other weeks will be removed.

An activity starts and ends on the same day. A start and length that run past midnight aren't saved: That runs past midnight. An activity starts and ends on the same day.

Delete removes the activity after a confirmation. For a weekly activity, every week's occurrence goes.

Agents connected over MCP can change activities too, for example:

• Move the dentist appointment to Thursday at the same time.
• Make the weekly gym on Monday start at 07:00.
• Delete the Spanish class on Wednesday.
• I'm sick today; move today's plans to tomorrow.

The agent uses these tools:

Moving a weekly activity moves the whole series. See Calendar tools and Connect Claude Code.
