Business Days Calculator is now live on Tools.Town — a practical tool for counting the number of working days between two dates, automatically skipping weekends and any custom holidays you specify.
Whether you’re setting a project deadline, calculating an SLA window, or figuring out how many billing days are in a month, this tool gives you the exact number in seconds.
What Does It Do?
Day Count
Count the exact number of business days (Mon–Fri) between any two dates.
Skip Holidays
Exclude specific public holidays or custom non-working dates from the count.
Add Days
Start from a date and add N business days to find the resulting deadline date.
All calculations run locally in your browser — no dates are sent to any server.
How It Works
Pick start & end
Select your start and end dates using the date picker. The tool accepts any range.
Add holidays
Optionally mark specific dates as non-working (public holidays, company shutdowns).
Get the count
The business day count updates instantly — total days, weekends excluded, and net working days.
Why We Built It
Calendar math sounds simple until you’re staring at a client contract that says “delivery in 15 business days” and you need to know which calendar date that lands on. Standard date calculators count all days. Project managers, HR teams, lawyers, and finance teams all need the working-days count. This tool handles the weekend and holiday logic so you don’t have to count boxes on a wall calendar.
