Use the toolbar at the top:

1. Pick a preset from the dropdown: Today (default), Yesterday, Last 7 Days, Last 3 Weeks, Month to Date, Last 3 Months, Quarter to Date, Year to Date, All Time or Custom.
2. Or type/pick dates in the two date boxes; the preset switches to Custom automatically (or back to a preset if your dates happen to match one).

The dashboard reloads immediately – there is no Search button – and the chosen dates are written into the page address so you can bookmark or share the view. All Time starts on 1 January 2000.
