As mentioned above, the region you select in Windows is important. Some apps and data use your reginal format settings to adjust their dates and times.
Below is how to change your reginal format in Windows 11.
Windows 11 has a centralized location for majority of its settings. From system configurations to creating new users and updating Windows, all can be done from the System Settings pane.
To get to System Settings, you can use the Windows key + i shortcut or click on Start ==> Settings as shown in the image below:

Alternatively, you can use the search box on the taskbar and search for Settings. Then select to open it.
Windows Settings pane should look similar to the image below. In Windows Settings, click Time & language, then on the right pane, and select the Language & region tile to expand it.

On the Language & region settings pane, under Region, click the Reginal format tile, and select the language to use for your reginal format.
In Windows, the recommended language is one that matches Windows display language.

Use the drop-down button to select the language you want from the list.

Some apps may need to be closed and reopened to see the formatting changes.
Alternatively, on the same Time & language > Language & region, under Related settings, click Administrative language settings.

On the Region window, under Format, select the language and location that best matches your reginal format settings.

That should do it!
