How this calculator counts

The calculator counts the days after the start date up to and including the end date, then removes Saturdays, Sundays and the holidays in the set you choose. By default that set is the 11 US federal holidays on the day they are observed, so a holiday that lands on a Saturday removes the Friday before. The Federal Reserve set keeps Saturday holidays where they fall, because Reserve Banks open that Friday, and the NYSE set adds Good Friday. Turning on “Count the start date” includes both ends, which matches Excel’s NETWORKDAYS. Every answer is calculated from the same rules in your browser, using your own time zone for “today”. The full rules and sources are on the methodology page.

Business days vs calendar days

Calendar days count every day on the calendar. Business days count only the weekdays when offices are open. The gap grows with weekends and holidays, which is why “5 business days” usually means a full week or more.

Example: from Monday, November 23, 2026 to Monday, November 30, 2026 is 7 calendar days but only 4 business days. The count skips the weekend of November 28–29 and Thanksgiving on Thursday, November 26.

There is no fixed conversion rate, because holidays are uneven. Five business days is seven calendar days in a week without holidays, but over a longer stretch the ratio drifts: 20 business days from Monday, November 2, 2026 ends on Wednesday, December 2, 2026, which is 30 calendar days later, because Veterans Day and Thanksgiving fall inside the window. When the exact date matters, count it rather than multiplying.

Use business days for deadlines that say “business days” or “working days”, such as processing times or notice periods. Use calendar days, the “All days” option above, for anything that runs every day, such as a countdown or a 30-day return window.
