Business Days Calculator

Count the exact number of business days between any two dates — weekends and public holidays are excluded automatically, so your deadlines and delivery dates are always right.

Most date apps only count raw calendar days. This one does the working-day math the way your office actually runs: it skips Saturdays and Sundays, drops the public holidays for your country, and lets you set your own weekend and workday hours. Whether you are pricing a contract, planning a sprint, or projecting an invoice due date, you get the answer in seconds — no spreadsheet formula required.

WHAT YOU GET
- The precise working-day count between a start and end date, with weekends and holidays broken out separately
- A future date by adding working days forward, or a past date by subtracting them
- Deadline mode that works backward to tell you the latest date you can start and still finish on time
- Public holiday packs for the United States, United Kingdom, Canada, Australia, Germany and India, plus your own custom holidays
- Saved calculations organized into folders and favorites for instant reuse
- Working days remaining in the current week, month or quarter, with a shareable CSV or summary of any result

PERFECT FOR
- Project managers mapping timelines and sprint windows
- Finance and payroll teams tracking payment and invoice terms
- Lawyers and HR staff counting statutory notice or filing periods
- Freelancers and contractors setting realistic delivery dates

WHY NOT JUST COUNT ON A CALENDAR?
Flipping through a calendar and subtracting weekends by hand is slow and easy to get wrong — and it silently ignores public holidays that push your real deadline out by days. This app applies your country's holidays and your own weekend rules every single time, so the number is one you can actually commit to.
