It depends on what you mean by business day. Often you will hear you have so many business days to get something like a payment in to a business. Business days in this context are Monday through Friday. Saturday and Sunday are not normally considered business days. If you are referring to a normal work day or business day in the context of hours worked the following is correct.A business typical day is 8 hours. A week is 40 hours. A month is 173.34 hours and a year is 2000 hours (in the US). The rule of thumb is 8am to 5pm including a 1 hour lunch.There are many variations but the most common is working four 10 hour days rather than five 8 hour days.Hope that helps!
