The Date Selector allows you to select a date by clicking on in. Depending on screen resolution, it will generally show the previous and upcoming week or so. The Date Selector can also be dragged to the left or right, allowing you to quickly select dates beyond the range shown by default.
The Date Selector line above the calendar is indented to provide quick and easy access to dates most likely to be of interest. The Time Navigation Controls can also be used to select specific dates, or navigate the calendar by days or weeks at a time.
