Learn the simplest way to change the first day of the week from Sunday to Monday or Monday to Sunday in simple steps.
By default, Windows 11 automatically sets the first day of the week according to your region. For example, according to my region settings, Windows 11 automatically sets Sunday as the first day of the week. But what if you want to change the first day of the week without changing your region or country? For instance, I prefer to have Monday as the first day of the week instead of Sunday.

The good thing is that it is pretty easy to do. In this quick and straightforward tutorial, I will show the steps to change the first day of the week in the Windows 11 calendar. Let’s get started.
