Results are rounded for display; the underlying calculation keeps full precision.
FAQ
What counts as a working day?
Working days are Monday through Friday; Saturdays and Sundays are excluded and reported separately.
Are both endpoints included?
Yes. The start and end dates are both counted when they land on a weekday.
Are public holidays removed?
No. Only weekends are excluded; subtract public holidays separately using a holiday calendar.
Does the Working Days Calculator send my data to a server?
No. The Working Days Calculator runs entirely in your browser — your inputs never leave your device, and nothing is uploaded or stored.
Worked example
A 30-day month with 4 full weekends has 30 − 8 = 22 working days before public holidays.
