Working Days Calculator
Count working days between two dates, or add working days to a start date. Weekends are skipped. Optional US or UK public holidays for 2026–2027.
Frequently asked questions
Is today counted?
In add mode, the start date is day 0. The first counted day is the next working day after the start.
Holiday on a weekend?
The weekend is already skipped, so that holiday is not counted twice. Holiday packs currently cover 2026–2027 observed dates.
