Business Days Calculator

Count business days between two dates, or add working days to a date, skipping weekends and your holidays. Choose your weekend days. Free.

Working days, not calendar days

Deadlines, shipping times and notice periods are often counted in business days, which skip weekends and public holidays. Enter two dates to count the working days between them, or a start date and a number of business days to find the end date. 2026 has 261 weekdays. Add your own holidays, one date per line, and choose a different weekend such as Friday–Saturday if that's where you work.
