Business days versus calendar days

A business day is any weekday, Monday to Friday. Weekends do not count, which is why 66 business days stretches across 92 calendar days rather than 66. As a rough guide, every five business days adds seven calendar days, so the gap between the two figures grows by about two days a week.

What about public holidays?

Federal holidays fall inside this range, so the answer changes depending on whether your agreement counts them. Excluding weekends only gives Tuesday, June 23, 2026. Also excluding US federal holidays pushes it to Monday, June 22, 2026, 1 day later.

The holidays skipped are:

Federal holidays are the national set. State holidays, company shutdowns and observances in other countries are not included, so check your own calendar for anything contractual.

Where this matters

Business-day counting is the default in contracts, refund windows, notice periods, court filing rules and shipping estimates, precisely because it does not punish a deadline for landing on a weekend. The convention is almost always to exclude the starting day and count from the next working day, which is what this page does. If your agreement says "within 66 business days", June 23, 2026 is the usual reading, or June 22, 2026 if holidays are excluded too.
