Working Hours Between Dates Calculator

About this calculator

This calculator counts the number of business days (Monday through Friday) between a start and end date, excluding weekends, then multiplies that count by a fixed number of hours per day to give total working hours across the range. It doesn't assume any particular workday length or account for public holidays unless you factor those in separately.

HR and payroll administrators, project managers, and freelancers or contractors billing by the hour use working-hours totals like this to estimate labor cost across a date range, set project timelines, or reconcile time sheets against an expected number of billable hours for a period.
