How do US federal holidays affect the next business day?

They are excluded, so the next business day moves to the next open day after weekends and any company closures you add.

Do state holidays matter?

Yes if you exclude them. Add state or company closures as custom holidays to keep results accurate.

What about Thanksgiving week?

Thanksgiving and the following day can both be excluded, pushing the next business day to the next open Monday.

Can I exclude weekends and holidays together?

Yes. Set the weekend pattern and holiday list in the calculator to remove both before returning the next business day.

No. It is educational. Results depend on your inputs and assumptions and are not guaranteed.

Next business day US explained

The next business day US depends on US federal holidays, state holidays you exclude, and company closures. Set the right holiday list, weekend pattern, and mode in the business day calculator to exclude weekends and holidays together before you promise a date. A Thanksgiving-style week can push results into the following Monday when both Thursday and Friday are excluded.

US holiday notes

Federal holidays like New Year’s Day, Independence Day, Thanksgiving, and Christmas remove working days. State holidays vary; add them if they matter. Company closures around Thanksgiving or Christmas can further push the next business day. Set the holiday year that matches your date to avoid wrong-day shifts.
