Determining the first day of the timesheet week and selecting the week that is displayed
The day of the week that starts the week is determined by the selection you made in the Timesheets preference in the System view of the Preferences window. You'll select the day using the drop down menu of the My Week Starts on field.
The seven-day week that includes the system date appears in the Week Of field by default.
Click the right or left arrows to display the previous or following week.
Click the Calendar icon to display the Calendar (week selection) window, where you can select a date. The seven-day week that includes the selected date appears in the Week of field.
