In the Tools > Preferences > Calendar & Activities, we can define an other First day of the week in the Calendar Preferences. By example, I decide to change this value in Monday.
If I go to the History List, and I change the filter of the dates to Last Week or Current Week, the first date will be always the sunday, and not the first day of the week that I define in the Calendar Preferences.
It will be very insteresting to link the value of the First day of the week to the dates filters of the History List. It's the same behaviour with the dates filters of the Task List.
