The best way to determine the calculation of the three (3) day refund policy of the business is to carefully read all documentation that you received from the business whose membership you purchased in that the documentation should define how the three (3) day period is calculated.If the time period is not defined, then custom and practice would be that the next business day (Thursday) would start the time period running. If the business is open on Saturdays and Sundays, those days are included in the calculation of the three (3) days.If those days of the week are not open for business, then Saturday and Sunday are not calculated.
