Business Days Calculator
The business days calculator finds the number of working days in the given period of time.

What Business Days Calculator does
The Business Days Calculator on Omni Calculator determines the number of working days between two dates, automatically excluding Saturdays and Sundays. Users input a start date and an end date, and the tool immediately returns the precise count of weekdays within that range, making it useful for project timelines, academic planning, or payroll deadlines. The result displays the total number of days alongside the business day count. Beyond basic date difference, the interface offers advanced options to include or exclude weekends and to add up to five custom holidays, allowing users to tailor the calculation to their specific operational calendar. A shareable link and clear reset function are also provided.
