Calculation of the working hours of the system: Yearly working days: 365 days - 104 days ( rest days) - 11 days (legal holidays) = 250 days Quarterly working days: 250 days ÷ 4 quarters = 62.5 days/quarter Monthly working days: 250 days ÷ 12 months = 20.83 days/month b. Conversion of daily and hourly wages: Calculation of the number of hours of work: multiply the working days of the month, quarter, or year by the daily number of eight hours. Daily wage: Monthly wage income ÷ Monthly payroll days Hourly wage: Monthly wage income ÷ (Monthly payroll days x 8 hours). Monthly payroll days = (365 days - 104 days) ÷ 12 months = 21.75 days c. Calculation of overtime pay: Overtime pay for each day of extended working hours: (actual working hours - 8 hours) × hourly wage × 150% Overtime pay for statutory public holidays: daily wage × 200% Overtime pay for statutory holidays: daily wage × 300%
