How to Fix Incorrect Excel Date Language and Windows Regional Settings
Product
Excel for Microsoft 365
Device & OS
Windows 10
Scenario
Following a Microsoft update, Excel displays dates in an unexpected language, and system regional settings keep reverting to incorrect defaults after a computer restart.
Observed behavior
Excel dates are shown in the wrong language. Manually fixing the Windows regional settings is only temporary, as they reset upon every system reboot.
Before you start

Before adjusting your language preferences, ensure you have saved all open Excel workbooks and that your computer is connected to the internet to run the Windows Update troubleshooter if needed.

Solution 1Recommended

Change the Preferred Display Language in Excel

Manually override the Windows preference setting within Excel to force it to use English (or your preferred language).

By default, Excel may match your Windows display language. Setting a specific language directly in Excel will ensure that dates and menus appear correctly, regardless of your system's current regional glitch.

1
Open Excel Options

Launch Excel and open any workbook. Click on 'File' in the top-left corner, then select 'Options' at the bottom of the left-hand menu.

2
Access Language Settings

In the Excel Options dialog box, click on 'Language' in the left pane to view your current Office language configurations.

3
Set the Preferred Language

Under 'Office display language', select 'English' (or your target language). Click the 'Move Up' button to place it at the very top of the list as the preferred language.

4
Apply and Restart

Click 'OK' to save your changes. Restart the Excel application for the new language settings to take effect on your date formats.

Frequently Asked Questions

Why do my Excel dates show in a different language than my Windows system?

Excel may be configured to use a specific display language that differs from your Windows regional settings. You can check and modify this by going to File > Options > Language in Excel and setting your preferred language to the top of the list.

How do I stop Windows regional settings from changing after restarting?

Repeated changes after a reboot are often caused by incomplete or corrupted Windows updates. Running the Windows Update troubleshooter from the Settings app usually resolves this system configuration problem. If it continues, reaching out to the Microsoft Community is recommended.

Does changing the Excel display language affect my keyboard layout?

No, changing the Office display language only affects the language used for buttons, menus, and built-in elements like date formatting in Excel. Your Windows keyboard input language remains separate and is managed through Windows Settings.
