MacOS Agenda app: Change the number of days in the weekly display

Many macOS users use the standard agenda app that seamlessly synchronizes via iCloud with you all your other Apple devices such as the iPhone and iPad. Over the years, the Agenda app has been equipped with extra functions. Something that many agenda users are still missing is to adjust the weekly display.

When planning appointments in advance, it can be useful that the weekly display shows more than 7 days. Of course you can also switch to the monthly display, but this shows much fewer details about the agreements already made. On iMac, for example, there is enough room to display 14 days in the week display.

With the help of a ‘hidden’ terminal command, it is possible to adjust the number of days displayed in the weekly display. You can choose how many days you want to show in the weekly overview. You cannot adjust this in the preferences of the agenda app, but the adjustment is fairly easy to implement via Terminal.

Number of days in the agenda adjust weekly display

You can adjust the number of days to be displayed during the week display using the MacOS Terminal app. The steps below work from macOS 10.14 Mojave.

1. Make sure the agenda app is closed
2. Open the Terminal App from the folder: Programs ▸ Utilities
3. In Terminal, perform the command below:

$ defaults write com.apple.iCal n\ days\ of\ week XX

Replace the XX In the command due to a desired number of days. To display 14 days in the week display, enter the number 14 here, for 21 days you use 21 and so on. It is not advisable to fill in a value of more than 30 days, since the agenda window then becomes very unclear.

Restart after performing the command de agenda app and select the ‘week’ display. You do this on the button Week To click at the top of the window.

14 day weekly display in the agenda app

If you want a 14-day weekly display as shown above instead of the standard 7-day, you can use the command as follows:

$ defaults write com.apple.iCal n\ days\ of\ week 14

After performing the command, the agenda app will restart and select the week display.

Agenda Reduce weekly display to 7 days

If you want to return to the standard display of 7 days in the agenda app, you must implement the steps below. The adjustment can be canceled with the help of the ‘Delete’ parameter.

1. Ensure that the agenda application is closed
2. Open the Terminal App from the folder: Programs ▸ Utilities
3. In Terminal, perform the command below:

$ defaults delete com.apple.iCal n\ days\ of\ week

Then restart the agenda app, you will see that 7 days are displayed again in the weekly display.

Older versions MacOS and OS X

If you still use an earlier version of MacOS or OS X, it is also possible to adjust the display. In that case you have to use another terminal command, you can use it from OS X 10.8 to MacOS High Sierra 10.13:

1. Ensure that the agenda application is closed
2. Open the Terminal App from the folder: Programs ▸ Utilities
3. In Terminal, perform the command below:

$ defaults write com.apple.iCal CalUIDebugDefaultDaysInWeekView XX

Replace here too XX Again due to the number of days you want to show in the weekly display.

Restart after carrying out the command the agenda or iCal app.
