- Device & OS
- not provided
- Scenario
- Viewing a calendar list view in a SharePoint site that has its language and regional settings configured to Italian.
- Observed behavior
- The calendar year view incorrectly renders 'aaaa' instead of displaying the actual numerical four-digit year.
Ensure you have administrative privileges for your Microsoft 365 account and the affected SharePoint site to check regional settings and submit support tickets.
Verify and Align Regional Language Settings
Check for inconsistencies across your SharePoint site, Microsoft 365 account, Office settings, and browser.
Sometimes conflicting language settings between the browser and Microsoft 365 can trigger localization display bugs. Ensuring all settings are aligned is the first troubleshooting step.
Navigate to your SharePoint site, click the gear icon, and go to 'Site Information' > 'View all site settings'. Click 'Regional settings' to verify the current language.
Log into your Office 365 account, open your profile settings, and ensure the language and region match your SharePoint site.
Open your web browser's settings menu, locate the language preferences, and confirm that the primary display language matches your Office 365 and SharePoint settings.

Escalate the Defect to Microsoft Support
Since this is a known localization defect with the Italian language setting, Microsoft's development team must investigate and patch the service.
