In a career setting, 3 business days refers to 3 working days, excluding weekends and public holidays. Typically, business days are Monday through Friday and do not include weekends. This means that if something will take up to 3 business days to process, it does not necessarily mean only 3 days. It is also important to consider that a business day is generally from 8:00 am to 5:00 pm. Therefore, the calculation for business days takes into account both the day and time of day the action is taking place. For example, if you order a package on a Friday evening, it may not be processed until Monday and received on Thursday. However, if the order is placed on a Friday morning, it could be received as early as Wednesday.
