Business Days Calculator

Find the exact number of working days between two dates by automatically excluding weekends.

Last updated: August 2026

Calculate True Working Time

When planning corporate projects, standard calendar days don't give you an accurate representation of how much actual working time you have. Our business days calculator automatically strips out weekends so you can accurately plan sprints and delivery dates.

Ideal for Shipping, Logistics, and Legal Deadlines

If a package takes "3-5 business days" to arrive, or a contract gives you "10 business days" to respond, calculating the exact date manually gets confusing fast whenever the timeframe crosses a weekend. Just plug the dates in to get an instant answer.

Worked Example: Shipping Window

A package ships on a Thursday with a stated 3-5 business day delivery estimate. Counting forward while skipping the weekend: 3 business days lands on the following Tuesday, and 5 business days lands on Thursday - so the real-world delivery window spans 5-6 calendar days, not 3-5.

Tracking payroll cycles or employee PTO instead of a shipping or contract deadline? Our Workdays Calculator uses the same weekend-excluding math, framed for HR and payroll.

Frequently Asked Questions

A business day is typically any official working day from Monday through Friday. Weekends (Saturday and Sunday) are excluded from the calculation.
Currently, the calculator strictly excludes standard weekends (Saturdays and Sundays). Public holidays vary wildly by country and region, so they must be subtracted manually if they fall within your timeframe.
Enter the ship date as your start date and count forward. For example, if a package ships Thursday with '3-5 business days' delivery, it would arrive between Tuesday (3 business days later, skipping the weekend) and Thursday (5 business days later) of the following week.
Many contracts and legal notices specify a response window in business days (e.g., '10 business days to respond'). Enter your notice date as the start date, then count forward the required number of business days - the calculator's weekend exclusion matches how these clauses are typically interpreted, though always check your specific contract language since some agreements define 'business day' differently (excluding public holidays, for instance).
In corporate, legal, and shipping environments, timelines are strictly measured in working time. 5 business days can equal 7 or more actual calendar days depending on where the weekend falls, which matters a lot when a contract or SLA is on the line.
This calculator only counts whole calendar days, not hours. Some contracts or carriers define a business day as ending at a specific cutoff time (e.g., 5pm) - check your specific terms if precise timing matters, since an order placed after a carrier's cutoff may not count until the next business day.
