How to Change Date Format in Windows 11 to MM/DD/YYYY: A Guide

By / September 1, 2025

Have you noticed that Windows 11 doesn’t always display dates the way you prefer? For example, you might see DD/MM/YYYY (day-month-year) but prefer the U.S. style MM/DD/YYYY (month-day-year). Thankfully, Windows 11 gives you full control over date formats.

In this guide, I’ll walk you step by step through how to change the date format to MM/DD/YYYY so your calendar, taskbar, and apps display dates the way you want.

Why Change the Date Format in Windows 11?

Everyone has different preferences—and sometimes, different requirements:

  • Regional Differences – The U.S. uses MM/DD/YYYY, while many other countries use DD/MM/YYYY.
  • Consistency – You may want your PC to match your workplace or official documents.
  • Readability – Some people find one format easier to read at a glance.
  • Avoiding Confusion – If you regularly share documents internationally, mismatched formats can cause errors.

Where Does Windows 11 Show the Date Format?

Changing the date format affects how the date is displayed in:

  • Taskbar clock
  • File Explorer (e.g., file modified dates)
  • Apps that rely on Windows regional settings
  • Microsoft Office apps (Word, Excel, Outlook, etc.)

Method 1: Change Date Format via Settings App

This is the easiest way for most users.

Steps

  1. Press Windows + I to open Settings.
  2. Go to Time & language > Language & region.
  3. Scroll down and click Regional format.
  4. Select Change formats.
  5. Under Short date and Long date, choose a format with MM/DD/YYYY.

Now your PC will display dates in the U.S. style format.

Method 2: Change Date Format via Control Panel

The Control Panel still gives deeper customization options.

Steps

  1. Press Windows + R, type control, and hit Enter.
  2. Go to Clock and Region > Region.
  3. In the Formats tab, click Additional settings.
  4. Switch to the Date tab.
  5. For Short date, type: MM/dd/yyyy
  6. For Long date, you can choose something like: dddd, MMMM dd, yyyy
  7. Click Apply and OK.

💡 This method is useful if the Settings app doesn’t show the exact format you want.

Method 3: Change Date Format Using PowerShell

If you’re comfortable with commands, PowerShell can do it quickly.

Steps

  1. Press Windows + S, type PowerShell, and run it as admin.
  2. Enter this command: Set-Culture en-US
  3. This will set your system culture to U.S., which uses MM/DD/YYYY format.

👉 Keep in mind this may also affect other region-based settings like currency.

Method 4: Change Date Format via Registry Editor (Advanced)

This is a more advanced method—use it carefully.

Steps

  1. Press Windows + R, type regedit, and hit Enter.
  2. Navigate to: HKEY_CURRENT_USER\Control Panel\International
  3. Find these values and change them:
    • sShortDate → M/d/yyyy
    • sLongDate → dddd, MMMM dd, yyyy
  4. Restart your PC for changes to apply.

⚠️ Only use this if other methods don’t work.

Will Changing the Date Format Affect Apps?

Yes, but in a good way. Most Windows apps—including Microsoft Office, Outlook, and File Explorer—will automatically follow your system’s new date format.

However:

  • Some third-party apps may have their own date settings.
  • Cloud services (like Google Drive) might use their own region preferences.

Troubleshooting Common Issues

  • Date format didn’t change on taskbar – Make sure you restarted your PC after applying changes.
  • Apps still show old format – Check if the app has its own date settings.
  • Wrong order still showing – Verify that your system language and region are set to United States if you want MM/DD/YYYY.

Tips for Managing Date Formats

  • Always use leading zeros (MM/DD/YYYY) for clarity (e.g., 03/05/2025 instead of 3/5/25).
  • If you often work internationally, consider using YYYY-MM-DD (ISO format) for documents to avoid confusion.
  • Keep both short date and long date customized to match your needs.

Conclusion

Changing the date format in Windows 11 to MM/DD/YYYY is quick and simple. Whether you use the Settings app, Control Panel, PowerShell, or Registry Editor, you can easily customize how dates appear across your system.

This small tweak makes your PC feel more familiar and helps you avoid confusion—especially when working with others who use the same format.
