Real-Life Uses
Small Business Owners
"If I ship an order today, when will it arrive if it takes 5 business days to deliver?"
HR Professionals
"An employee gave 2 weeks' notice – what's their last working day (excluding weekends and company holidays)?"
Project Managers
"How many working days do my team have to complete this phase of the project?"
Finance Teams
"Our invoice terms are net 30 business days – when is payment actually due?"
Fun fact: The most common calculation is adding 5 or 10 business days – probably for short-term deadlines and quick turnaround tasks! Many users also add holiday dates (like Christmas, New Year's) to the non-working list.
