View excluded dates
US results follow the standard federal Monday–Friday holiday calendar. They are not bank, ACH, Federal Reserve or stock exchange calendars. UK results use the selected region’s bank holidays; individual employers may differ.
Which dates are counted?
The default includes both the start and end date, but only if they are working days. Turn either checkbox off to leave that endpoint out. A weekend or listed holiday never becomes a working day just because an endpoint is included.
For 1–5 June 2026, the US federal calendar gives 5 business days with both endpoints included, or 3 with both excluded.
Coverage and limitations
Verified holiday dates cover 1 January 2026 to 31 December 2028. The calculator accepts up to 1,000 business days, but both the input and resulting date must remain within that coverage. UK regions differ, and additional bank holidays may be announced after this snapshot.
