How to Show Week Numbers in Outlook Calendar on Windows 11
Week numbers in Outlook for Windows 11 show the numerical week of the year from 1 to 52 right on your calendar grid. This view lets you track project deadlines and plan schedules across team projects without counting dates by hand.
Microsoft includes this feature in the built-in Outlook app so you can turn on the date markers in your calendar settings. You only need a few clicks to add these numbers to your monthly and weekly views.
Enable week numbers in Outlook Calendar by going to File, Options, Calendar, and then checking “Show week numbers.” This setting will then display the week number next to each date in your calendar view.
Show or hide “Week numbers” in the Outlook calendar
You can show week numbers in the Outlook calendar by opening the application settings, going to the calendar options, and checking the box that turns on week numbers. This feature adds the exact week of the year next to your dates, which helps you plan projects and schedules over long periods without having to count weeks manually on your screen.
Follow these steps.
Launch the new Outlook app on Windows 11 by opening the Start menu and selecting Start - All apps - Outlook app.
Alternatively, type Outlook into the Start menu search bar to launch the application.

Click the Settings button, represented by a gear icon in the top right corner, once the window loads.

Select the Calendar tab located in the left-hand sidebar of the Settings window.
Locate the 'View' section, then check the box next to "Show week numbers" to populate the grid with chronological markers.
Clearing the checkbox hides the numbers instantly if the extra data feels cluttered.

Active week indicators will now appear alongside your standard schedule inside "Week numbers".

The configuration process is complete.
