When using Microsoft To Do you may notice that when you want to set the Due Date to "Next Week" it sets it to Sunday by default. If your like me, you may want this to be Monday because that is when my work week starts.
This setting cannot be changed through Microsoft To Do, but instead it uses your Windows settings. Here is how to change it.
In Windows Search, type in "change the date and time formats" and open the settings page.
Click the "Change data formats" link near the bottom.
Change the First day of week to Monday.
Now go back to Microsoft To Do. Your Next Week is set to Monday!
