Questions
Is the start date counted as a business day?
No. Business day 1 is the next working day after the start date.
Which holidays are skipped?
The 11 U.S. federal holidays. When one falls on a Saturday it is observed on Friday, and when it falls on a Sunday it is observed on Monday. See the federal holidays list.
Can it match my company’s holiday calendar?
No. It covers weekends and U.S. federal holidays only, so adjust the result by hand for company or state holidays.
