If you track time, you can set the first day of your workweek and choose which time entry form QuickBooks displays when you click the Timesheet button on the toolbar.
QuickBooks adjusts your timesheets so that each weekly period begins with the day of the week you select. If a timesheet happens to be open when you make this change, the change does not occur in the timesheet until you close and reopen it.
This preference determines which time entry form appears when you click the Timesheet button on the toolbar or the Record Time button on the Employee list. QuickBooks provides two forms: one for entering the time spent by one person on a single job on a single date (the single activity entry form), and one for entering the time spent by one person on multiple jobs over longer periods of time (the weekly timesheet).
