One date per line in YYYY-MM-DD formatHow This Working Days Calculator Online Free Works
This working days calculator online free counts the number of business days between any two dates by walking the full date range and subtracting every day that falls on a weekend or a listed holiday.
Weekend days are configurable. The default is Saturday and Sunday, but you can toggle any day of the week as a non-working day. That makes it useful for 4-day work weeks, Middle Eastern calendars where Friday is a day off, or any custom schedule.
Add public holidays in the text field — one date per line — and the tool excludes them from the count automatically. It also shows the calendar date that falls exactly N working days from your start date, so you can find project deadlines in seconds.
