Except as otherwise provided by time period computations prescribed by statute, to compute the date an answer is due in civil actions, begin counting on the day following the day of service and count the number of days. If the last day falls on a Saturday, Sunday, or legal holiday, then the next regular business day becomes the day the answer is due. When the period of time is less than seven (7) days, intermediate Saturdays, Sundays, and legal holidays shall be excluded in the computation.
