Open Date CalculatorWhy Business Days Matter for Projects:
Most projects operate on business days (Monday-Friday), making it essential to exclude weekends when calculating timelines. Our business days calculator automatically excludes Saturdays and Sundays, giving you accurate working day counts for realistic project planning.
For example, a project with 30 calendar days actually has only about 22 business days. This difference is crucial for setting realistic expectations and avoiding missed deadlines.
