What this calendar calls a business day
A weekday that is not on the holiday list you are using.
A common business day, here, is a date that is open on both calendars. A weekend day you checked, or a holiday on that country’s list, closes it. If either side is closed, the date is not common.
The lists shipped with the tool are a 2026 starter set, not a legal gazette. The United States list follows the federal holidays, with Independence Day observed on Friday 3 July 2026 because 4 July is a Saturday. The United Kingdom list is England and Wales bank holidays, including the substitute Boxing Day on Monday 28 December 2026. Germany includes nationwide holidays only. India includes Republic Day, Independence Day, and Gandhi Jayanti. Add Holi, Eid, Diwali, and state holidays yourself.
