Why does Settings Time and Language keep resetting your preferred calendar format

Calendar formats in Windows 11 and Windows 10 keep resetting because the modern Settings app and the classic Control Panel often conflict with each other. A regional format controls how your PC displays dates, days of the week, and calendar styles like day-month-year or month-day-year.

Language mismatch errors or cloud profile sync bugs frequently overwrite your custom date settings after a restart. Fixing the calendar format reset issue means turning off automatic region sync in your Microsoft account and matching your display language directly to your preferred regional format.

⚡ Quick Answer

Settings Time and Language keep resetting your preferred calendar format because Windows syncs your regional settings with your Microsoft account profile or language packs, overriding your custom choices during reboots. Fix this by opening the classic Control Panel , selecting Region, and updating your format settings there.

Method 1Fixing Regional Formats Through the Classic Control Panel

Fixing regional formats through the classic control panel helps stop Windows from resetting your calendar preferences because the older tool saves changes more reliably than the modern Settings app . You can use this method to force your custom date and time styles to stay put across computer restarts by updating the region settings directly in the desktop Control Panel.

Follow these steps to update your regional format using the Control Panel :

  1. Click the Start button on your taskbar and type Control Panel into the search box.

  2. Click on the Control Panel app from the search results to open it.
  3. Look at the top right corner of the window and make sure your view is set to “Large icons” or “Small icons” so you can see all the options clearly.
  4. Click on the Region option. A new smaller window will pop open on your screen.
  5. On the Formats tab, look at the “Format” drop-down menu. Choose your preferred country or region from the list. This tells Windows which calendar and date style you want to use.
  6. If you want to customize your calendar specifically, look at the “Short date” and “Long date” options near the bottom of the window and select your favorite layout.
  7. Click the Apply button at the bottom right of the window, and then click OK.
  8. Restart your computer to see if your settings stay saved.

Method 2Copying Your Settings to Welcome Screen and New User Accounts

Copying your settings to welcome screen and new user accounts stops Windows from overriding your personal calendar choices with system defaults when the computer boots up. You can apply your exact date and regional preferences to the login screen and all new user profiles so your custom calendar format stays active from the moment you turn on your PC.

You can fix the calendar reset issue by copying your current regional settings so the regional settings apply everywhere on your computer, including the welcome screen and new user accounts. Note: This copying step requires administrator privileges on your computer.

  1. Open the classic Control Panel by typing Control Panel in your Start menu search bar and pressing Enter.
  2. Click on Region.
  3. In the Region window, click on the Administrative tab at the top right.
  4. Look for a button labeled Copy settings... and click on it. A new window will appear showing your current settings for the welcome screen and new user accounts.
  5. At the bottom of this new window, look for checkboxes labeled "Welcome screen and system accounts" and "New user accounts". Check both boxes.
  6. Click OK to save your choices.
  7. Click OK on the main Region window, and then restart your computer.

Method 3Adjusting Time and Language Settings in the Modern Windows App

Adjusting time and language settings in the modern Windows app fixes calendar format resets by making sure your country, region, and display language match each other. Mismatched regional options often trick Windows into reverting your calendar back to default settings, so lining up these choices in the main Windows Settings menu keeps your preferred calendar format working properly.

Here is how to check and fix your settings in the modern app:

  1. Press the Windows key and the letter I on your keyboard at the same time to open the Settings app.
  2. Click on Time & language from the menu on the left side of the screen.

  3. Click on Language & region.
  4. Look at the "Country or region" setting. Make sure it matches your actual physical location and your preferred calendar style.
  5. Scroll down to the "Regional format" section. Click the drop-down menu and choose the exact format that matches your preferences. If it is already set to your choice, try changing it to a different format, restarting your computer, and then changing it back to your preferred choice to clear out any stuck glitches.

  6. Check your "Preferred languages" list further up on the same page. Make sure your primary language matches your regional format. If you live in the United Kingdom, for example, having a US English language pack installed can sometimes trick Windows into resetting your dates.

Method 4Checking for Conflicting Group Policy or Sync Settings

Checking for conflicting group policy or sync settings helps you find out if a school network, work computer, or cloud account is forcing your calendar format back to default. Workplace rules and Microsoft account sync features often override personal computer tweaks in the background, so turning off these automated overrides lets your custom date and time choices stay saved.

Additionally, if you have cloud sync turned on, your Microsoft account might be pushing settings from an older device onto your current computer. Here is how you can check your sync settings:

  1. Open the Settings app by pressing the Windows key and I.
  2. Click on Accounts from the left menu.
  3. Click on Windows backup or Sync your settings depending on your exact version of Windows.
    Settings › Accounts › Windows backup
    Settings › Accounts › Windows backup
  4. Look through the options to see if your password, language preferences, or other settings are syncing with the cloud. If you notice that your profile keeps pulling settings from the cloud and messing up your computer, you can turn off synchronization for your preferences.

Unique Expert Tip: Fixing Corrupted User Profile Data

Fixing corrupted user profile data solves stubborn calendar format resets that happen when Windows loses the ability to save personal settings in hidden system files. Damaged profile folders prevent your computer from remembering changes you make, meaning you have to repair or replace the broken profile data so your custom calendar preferences can finally save correctly.

To fix a corrupted profile, you can create a brand new local user account on your computer, log into it, and see if your calendar settings finally stay saved. Note: This step requires administrator privileges.

  1. Open the Settings app by pressing the Windows key and I.
  2. Go to Accounts and then click on Other users or Family & other users.
    Settings › Accounts › Other users
    Settings › Accounts › Other users
  3. Click the button that says Add account or Add someone else to this PC.
  4. Choose "I don't have this person's sign-in information" and then select "Add a user without a Microsoft account".
  5. Type in a new username and password, then follow the onscreen instructions to finish creating the account.
  6. Click on the new account name and change its account type to Administrator.
  7. Sign out of your current user account and log into your new account. Change your calendar and regional formats here. Restart the computer to check if the issue is completely gone.
