Week numbers in Windows Calendar
To enable or display the ISO 8601 week number in Windows Calendar, you typically need to adjust the view settings:
Settings (Gear Icon) > Calendar Settings > Select "Week numbers"
* Ensure your system or application regional settings are set to follow ISO 8601 standards (weeks start on Monday) if the output varies.
Instructions étape par étape
- Open the Calendar app on Windows and click the gear icon (Settings).
- Choose "Calendar Settings".
- Under "Week Numbers", pick "First four-day week" for ISO 8601 numbering.
- Set the first day of the week to Monday for standard-compliant numbers.
Bon à savoir
As with Outlook, choose "First four-day week" rather than "First day of year", or the number shown in early January and late December can be off by one versus the ISO standard.
