Workdays Between Dates
Count working days between any two dates — weekends excluded
Business Days Calculator
What is this calculator for?
This tool counts the number of working days between two dates, automatically excluding all Saturdays and Sundays. Toggle the holiday option to also skip US federal holidays. It is designed for project planning, legal deadline tracking, payroll calculations, and any scheduling that operates on a Monday–Friday calendar.
Why it matters
Many contracts, legal filings, and employment agreements measure time in business days rather than calendar days. Manually counting working days is tedious and error-prone — especially across month and year boundaries or during holiday-heavy periods. This calculator eliminates that work instantly.

Frequently asked questions
How many workdays are in a month?
The number of workdays in a month varies. Most months have 20–23 workdays. January typically has 21, February 19–20, March 22, and so on. Use the calculator above to count the exact workdays in any specific month.
What is the difference between workdays and business days?
Workdays and business days are essentially the same thing — any day Monday through Friday that is not a public holiday. Some industries define business days slightly differently (e.g. banking vs. retail), but for most purposes the terms are interchangeable.
How many workdays are in a year?
A standard year has approximately 260–262 workdays (52 weeks × 5 days). After subtracting 10 US federal holidays, the typical number of working days in a year is about 250–252.
How do I calculate 10 workdays from today?
Set the start date to today and adjust the end date until the calculator shows 10 workdays. A rough rule: 10 workdays is usually about 14 calendar days (2 weeks).
Does the calculator handle month-end and year-end boundaries?
Yes. The calculator works for any date range regardless of month or year boundaries. It correctly handles February, leap years, and holiday-heavy periods like Christmas week.
