About the Working Days Calculator
Count the working days between two dates after taking out weekends and public holidays. It is useful for delivery estimates, notice periods, project plans and leave planning.
Choose your weekly days off (Saturday–Sunday, Friday–Saturday, Sunday only or none), pick a holiday preset, and add your own holiday dates.
The calculation runs in your browser, so the numbers you enter are not uploaded or stored.

Working Days Calculator FAQ
How does the working days calculator work?
Every calendar day from the start date to the end date, both included, is checked. Days off are removed first, then any holiday that falls on a working day. A holiday that lands on a weekend is not subtracted twice.
Are holidays for my country included?
Presets cover fixed-date national holidays only, such as 26 January and 15 August in India. Holidays that move each year, like Diwali, Eid, Holi or Easter, change by year and region, so add them in the custom box.
Are the start and end dates counted?
Yes. Both are included, so Monday to Friday of the same week is 5 working days.
Is this working days calculator free and private?
Yes. It is free with no sign-up, and the calculation happens on your device, so your numbers are never sent to a server.
