  • An array reference with two values: starting and ending hour of the day

• weekends - An array reference with values of the days that must be considered as non-working in a week. Defaults to [6,7] (Saturday & Sunday)
• holidays - An array reference with holiday dates in 'yyyy-mm-dd' format
• holidayfile - The name of a file from which predefined holidays can be excluded from business days/hours calculation. Defaults to no file
