Calculation method
The table counts weekdays in each month, then subtracts the listed U.S. federal holidays that fall on weekdays or are observed on weekdays. It is useful for planning, reporting, and estimating work windows before a detailed employer or bank calendar is available.
Company shutdowns, local holidays, and bank-specific schedules can change the actual working calendar, so the source and method should be checked before using the result for high-impact decisions.
