Multiply annual vacation in weeks by the number of days worked per week by the number of hours worked per day. An equation example is:
5 weeks per year x 5 days per week x 9 hours per day = 225 hours per year.
Divide that value by 52. That will give you the number of hours of vacation per week, or the hours per week value. The equation for this example is:
225 / 52 = 4.3269, which rounds to 4.33 hours per week.
Calculate the number of weeks worked in the year up to the pay cutoff date.
If an employee started Sept. 6, 2010, and the pay cutoff date is Dec. 31, 2010, then the total equals 16 weeks and four days. Four days is 4/5, or 0.8, of the five-day work week. So the total number of weeks is 16 + 0.8 = 16.8.
Multiply that value by the "hours per week value" you figured previously. The equation for this example is:
16.8 x 4.33 = 72.7, when rounding this answer.
Revise that answer to the nearest quarter hour. For this example, 72.7 becomes 72.75 hours. That is equal to one working week, three days and 3/4 hours.
