29 C.F.R. § 553.230.
Once the number of hours actually worked in the work period exceeds the overtime threshold, the employee must be compensated at one and one-half times the normal rate of pay. It does not matter how many hours an employee works in any given day during the work period, whether the day fell on a holiday, or whether the work was on a regularly scheduled day off; overtime is calculated on the total number of compensable hours worked in excess of the overtime threshold for the work period.
