Trying to add hours for a date in the past, but the employee's timesheet won't let you?
This usually happens because the employee's employment start date is set after the date you're trying to update. To add time entries for earlier dates, you'll need to adjust the employee's start date.
Updating the employment start date
Go to HR > Employees
Select the employee
Click the Profile option
Click Employment tab
Update the Employment start date to a date before the time entry you'd like to add.
Click Save.
Once the date has been updated, the earlier dates will become available and you'll be able to add time entries to the employee's timesheet.
