Three business days typically refer to three weekdays, excluding weekends and holidays.
For example, if you were told that something would be delivered within three business days and the delivery process started on a Monday, you could expect to receive it by Thursday.
However, if the delivery process started on a Friday, the three business days would not include Saturday and Sunday, so you would receive the item by Wednesday of the following week.
It's essential to consider any holidays or non-working days within the timeframe to accurately determine when the three business days will be completed.
