Frequently Asked Questions
What counts as a business day?
A business day is any day that is not a weekend (Saturday or Sunday) or a recognized holiday. In the US, there are 11 federal holidays. Some industries observe additional holidays. Business days are used for shipping estimates, legal deadlines, and financial settlement periods.
How many business days are in a year?
A typical year has 260 weekdays. After subtracting 11 US federal holidays (some of which may fall on weekends and are observed on the nearest weekday), there are usually 249-252 business days per year. The exact number varies by year depending on how holidays fall.
Why do business day calculations matter?
Many legal, financial, and contractual deadlines are measured in business days, not calendar days. SEC filing deadlines, bank processing times, shipping guarantees, warranty periods, and court filing deadlines all commonly use business day counts. Getting the count wrong can result in missed deadlines.
