How to use the Business Days Counter

A "10 working day" delivery promise is very different from 10 calendar days, and miscounting weekends can make you miss a deadline or misquote a client. This business days between two dates calculator starts from the exact day count between two dates; weekends are then excluded using simple week math shown below, so you can plan project timelines, notice periods and shipping estimates on working days only.

  1. Enter your start date in the first date field.
  2. Enter your end date in the second date field.
  3. Click Calculate to count the working days instantly.
  4. Read the breakdown: business days, total calendar days and excluded weekend days.
  5. Manually subtract any public holidays in your country for the final count.

Formula

Logic: business days = total calendar days − weekend days − public holidays. Weekend days = 2 × (full weeks in range) + extra weekend days in the partial week. Public holidays vary by country and are subtracted manually.

Worked example

From Monday 12 October 2026 to Friday 23 October 2026 the tool shows 11 calendar days. That spans one full weekend (2 days), so business days = 11 − 2 = 9 working days. A "10 working day" job starting 12 October is therefore due around 26 October.
