- Product
- Microsoft Outlook
- Device & OS
- not provided
- Scenario
- Viewing the yearly calendar schedule and weekly breakdowns in Outlook.
- Observed behavior
- Outlook displays 53 calendar weeks when the first day of the week is set to Monday, but correctly displays 52 weeks when the week-start setting is changed to Sunday.
Before modifying your calendar configurations, take note of your current 'Start week on' setting so you can easily revert it if your workplace requires specific weekly schedules.
Change the 'First Day of Week' Setting
Adjusting the first day of the week from Monday to Sunday aligns the calendar with standard non-ISO display logic, effectively resolving the 53-week issue in Outlook.
Outlook uses different numbering systems depending on which day you designate as the start of the week. Setting Monday as the first day often triggers ISO 8601 week numbering, which can result in 53 weeks for specific years like 2023.
Launch Microsoft Outlook, click on 'File' in the top-left corner of the ribbon, and select 'Options' at the bottom of the left-hand menu.
In the Outlook Options dialog box, click on the 'Calendar' tab located in the left pane.
Under the 'Work time' section, locate the 'First day of week' dropdown menu. Change the selection from 'Monday' to 'Sunday'.
Click 'OK' to save your changes. Restart Outlook to verify that the calendar now displays 52 weeks.
Disable Interfering Third-Party COM Add-ins
If adjusting the start day of the week does not fix the calendar display, a third-party add-in might be forcing a specific calendar view.

Frequently Asked Questions
Why does a year sometimes have 53 weeks?
A standard year has 365 days (52 weeks and 1 day), and a leap year has 366 days. According to the ISO 8601 standard, which starts weeks on Monday, if a year begins on a Thursday (or Wednesday in a leap year), the year will mathematically stretch into a 53rd week. Outlook reflects this when Monday is set as the start of the week.
Will changing the first day of the week affect my scheduled meetings?
No, altering the 'First day of week' setting only affects how the calendar is visually laid out in your Outlook interface. The specific dates and times of all your scheduled meetings and appointments remain completely unchanged.
Can I manually delete the 53rd week in Outlook?
You cannot manually delete a week from the Outlook calendar interface because it is generated automatically based on system logic and calendar rules. You can only alter its display by changing the 'First day of week' setting.
