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?
Perhaps I wasn't clear, I've already made sure that the admin preference is set to first day of week for calendars: Sunday (as saturday is the last day of our week) . I want the timescale to display the date of the last day of the week, instead of the first.
IE: instead of 20 I want it to show 26.
It makes it quite confusing for us and for our clients if we switch to/from referring to the beginning or ending of the week and thus we always refer to Week Ending.
go to admin. from the drop down menu select admin preference and then general then you can make ur changes.
