Business days calculator
Count business days between two dates, or add business days to a date. Weekends and US federal holidays are skipped on their observed dates, and you can add state holidays or office closures.
| Skipped weekday | Why |

Business days here are Monday to Friday, minus US federal holidays on their observed dates and any days you add. Contracts, courts, lenders and states can define business days differently (some count Saturdays), so check the definition that applies. Not legal advice.
Business days are usually Monday to Friday, minus holidays. Counting starts the day after the start date. Five business days after Friday, November 20, 2026 is Monday, November 30, because Thanksgiving on the 26th is skipped. December 1 to December 31, 2026 has 21 business days. Your contract's definition decides which days count.

Questions about the business days calculator
How do you count business days between two dates?
Start the day after the first date and count each Monday to Friday through the end date, skipping holidays. From December 1 to December 31, 2026 there are 22 weekdays; Christmas falls on a Friday, so there are 21 business days.
Which holidays does the calculator skip?
The 11 legal public holidays in 5 U.S.C. 6103: New Year's Day, Martin Luther King Jr. Day, Washington's Birthday, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving and Christmas, on the dates federal offices observe them.
What if a holiday falls on a weekend?
Federal offices observe a Saturday holiday on the Friday before and a Sunday holiday on the Monday after. July 4, 2027 is a Sunday, so Monday, July 5, 2027 is skipped. Your contract or state may treat this differently.
Are Saturdays business days?
Not here. Some rules count Saturdays: the TRID Closing Disclosure rule, for one, treats every day except Sundays and federal holidays as a business day. Use the closing date calculator for that count.
Does the start date count?
Usually not. Most contracts start counting the day after the event, so day 1 is the next business day. Tick the box to count the start date too if your contract says so.
Can Closingbird count business days on every deadline?
Yes. Each deadline in Closingbird can be set in calendar or business days, with weekends and US federal holidays skipped, and moves when the date it depends on changes.
