Business days calculator

Weekends are always skipped. U.S. federal holidays are skipped on their observed dates unless you turn that off.

Rules used

  • Counting includes the end date and leaves out the start date, so Monday to the following Monday is 5 business days. Tick the start-date box to count both ends.
  • Adding starts the next business day after the start date: 1 business day after a Friday is the following Monday. Adding 0 returns the start date.
  • Holidays are the eleven U.S. federal holidays from this list. When one falls on a Saturday, the Friday before is skipped; when it falls on a Sunday, the Monday after is skipped. That is how federal offices and many employers observe them.
  • Bank, stock market, state, and company holidays can differ from the federal list. Turn holidays off to count weekdays only.
