Changing the start date of the time period to any other day

If you want to change the start date of the time period to any other day, then you need to go to the time periods and select the time period you want to change. In there you can change the start day of the week. You will have to rebuild the time period calendar after you change the start day for the change to be effective.

For example I wanted to change the start day to Sunday for my biweekly time period.
