About this Working Days Calculator
Working days (or business days) are the weekdays — Monday through Friday — that form the backbone of commercial, legal, and contractual timelines. Counting them correctly matters for project planning, invoice payment terms, legal notice periods, delivery estimates, and employment contracts. Our working days calculator goes beyond simply subtracting weekends. It also excludes public holidays for five English-speaking countries — the US, UK, Australia, Canada, and New Zealand — using hardcoded holiday dates for the current year and the years immediately before and after. The calculator clearly lists every public holiday excluded from your range so there are no surprises. The 'Count forward' mode solves a different but equally common problem: if a contract says payment is due within 30 working days, or a notice period is 20 working days, when exactly does that end? Enter your start date and the number of working days, and the calculator gives you the precise end date while accounting for weekends and bank holidays.
Frequently Asked Questions
A working day (or business day) is typically Monday through Friday, excluding weekends. Public holidays may also be excluded depending on your country, though our base calculator excludes weekends only.
Count all days between the start and end date, then subtract Saturdays and Sundays. For long periods, this is easiest with a calculator. Our tool handles all the counting automatically.
Shipping and delivery estimates are almost always in business days (Mon–Fri). A 5 business day delivery ordered on a Wednesday would typically arrive the following Wednesday (skipping the weekend).
Yes, significantly. The UK has 8 bank holidays per year, the US has 11 federal holidays, Canada has 9 federal statutory holidays (provinces add more), Australia has around 8 national holidays (states add others), and New Zealand has 11 public holidays.

Use the 'Count forward from a date' mode. Enter your start date (e.g. today), enter the number of working days in your notice period (e.g. 20), and the calculator will give you the exact end date excluding weekends and public holidays for your country.
