What is Business Days?

A workday-aware date calculator: either the count of Monday–Friday days between two dates, or the date you land on after adding a number of business days.

How it works

Weekends (Saturday/Sunday) are skipped automatically; an optional comma-separated holiday list lets you exclude specific dates.
