Calculate Business Days Between Dates

Need to know exactly how many working days you have to complete a project? Our Business Days Calculator easily computes the number of working days between any two dates by automatically excluding weekends.

Why Use a Business Days Calculator?

When dealing with professional deadlines, contracts, and delivery times, standard calendar days are often irrelevant. Many legal and business agreements specify timelines in 'business days'. Calculating this manually can be tedious and prone to errors, especially over long periods. This calculator instantly gives you the precise count of Monday-to-Friday working days.

Working Days Algorithm

$$\text{Total} = \sum_{d=start}^{end} \begin{cases} 1 & \text{if } d \notin \{Sat, Sun\} \\ 0 & \text{otherwise} \end{cases}$$

Iterates through each day and only increments the counter if the day is not Saturday (6) or Sunday (0).

Numerical Example Calculation

A 14-calendar-day sprint starting on Monday contains exactly 10 business days.
