Working days vs calendar days
Project plans and contracts often count in business days, not calendar days — a 10-business-day turnaround spans two calendar weeks. This calculator counts working days (Monday–Friday) between any two dates, optionally skipping regional holidays, so you know your true deadline. Useful for sprint planning, contract response windows, and shipping estimates.
