We usually refer to our weeks as "week ending" however the timescale shows the week beginning date.
ie. Last week was "week ending october 26". When I chose month/week as my interval it shows "Oct 20" as you can see in the picture below:

Our weeks end on saturdays (thus start on sundays) and so that's how I have the admin preference set. Does anyone know of a way to change it so it shows the date as the last day of the week instead of the first?
