How 15 business days from today is counted

A business day is a Monday through Friday that is not a public holiday. To find the date 15 business days from today, start with tomorrow and count forward, skipping every Saturday, every Sunday and every U.S. federal holiday that lands on a weekday. The date you reach on the 15th counted day is the answer shown above. Today itself is day zero and is never counted, which is the rule used by courts, agencies and most contracts.

Where this number comes up

15 business days is a three week working window used in many government notices and for a bank to release a large deposit. When a document says "within 15 business days" it almost always means 15 working days after the event, not including the day of the event. If it says "15 days" with no qualifier, it usually means calendar days, which is a shorter window; the date calculator counts those.

Which holidays are skipped

This page uses the U.S. federal holiday calendar: 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 Day. When one of these falls on a Saturday it is observed on the Friday before, and when it falls on a Sunday it is observed on the Monday after, following the federal observance rule. The holidays actually inside this 15 day window are listed next to the answer, so you can check them against your own company or state calendar. Many employers skip Columbus Day or add the day after Thanksgiving; if yours does, use the business days calculator with the weekends only setting and adjust by hand.

Weekends only versus weekends and holidays

Shipping carriers and some banks count business days as weekdays only and keep working on holidays, which is why the page also shows the weekends only answer. The two dates differ whenever a federal holiday sits inside the window, and the gap grows around Thanksgiving, Christmas and New Year's Day, where one week can hold two holidays.

Checking the answer

The day by day table above lists all 15 counted days with their dates, so you can see exactly which days were skipped and confirm the result against a wall calendar. For a different start date, a count that is not 15, or counting backward from a deadline, open the business days calculator; the link under the answer opens it with today and 15 already filled in. To count the business days between two dates you already have, use business days between dates.

Questions people ask

Does "15 business days from today" include today?

No. Today is day zero. The first business day counted is the next weekday that is not a holiday. If a notice was received on a Friday, day one is the following Monday.

What if today is a weekend or a holiday?

The count simply starts from the next business day, so a Saturday, Sunday or holiday start gives the same answer as starting on the last business day before it.

Is this page updated every day?

Yes. The answer is calculated when the page loads, using today's date in U.S. Eastern time, and your browser checks it again against your own device's date.

How many calendar days is 15 business days?

Usually about 21 calendar days, since five business days make a seven day week, plus one day for each holiday in the window. The exact number for today is shown next to the answer.

Can I rely on this for a legal deadline?

Use it to check your own count, not as legal advice. Court and agency rules can define business days differently, add state holidays or move a deadline that ends on a closed day. When a filing date matters, confirm it with the court or agency.
