Business Days Calculator
Calculate the number of business days between two dates.
The days that count for work
Business days — weekdays, excluding weekends — are what deadlines and delivery times are usually measured in. This calculates the business days between two dates, so you can plan against the days work actually happens rather than the raw calendar total.
Enter two dates to count the business days between them.
Why business days matter for planning
So much of commercial and professional life runs on business days that mixing them up with calendar days is a real source of missed deadlines. A delivery promised in five business days is not five calendar days — weekends in between push the actual date later, sometimes by several days. This calculation excludes weekends automatically, giving the true working-day gap. A complete picture also depends on public holidays, which vary by country and would further reduce the count, so those are worth factoring in for your location. Understanding that business days and calendar days can differ substantially, especially across a period containing weekends and holidays, prevents the common planning error of expecting something sooner than the working calendar allows.

How do business days differ from calendar days?
Business days exclude weekends, so a five-business-day period spans more than five calendar days once the weekends in between are counted.
Does it include public holidays?
It excludes weekends automatically; public holidays vary by country and would reduce the count further, so factor those in for your location.
