What is the Working Days Calculator?

Find how many working days are between two dates – useful for project deadlines, notice periods, delivery estimates and leave planning. Choose your weekend (Saturday–Sunday, Friday–Saturday or only Sunday) and add public holidays. Or add a number of working days to a start date to find the due date.

How to use the Working Days Calculator

  1. Choose Count days or Add days.
  2. Pick dates and your weekend days.
  3. Add holidays (one date per line) if needed.

Tip

Some notice periods count calendar days, not working days – check your contract.

This Working Days Calculator is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
