Subtract Business Days Calculator
Move backward by a chosen number of Monday–Friday business days, with optional dates to exclude manually.
How days are subtracted
The starting date is not counted. The calculator moves backward and counts only eligible Monday-through-Friday dates.
result date = start date − requested eligible business days
Worked examples
One business day before Monday is Friday. Three business days before Thursday is Monday.
If the previous Friday is manually excluded, one business day before Monday becomes Thursday.
Weekend starts
Subtracting one business day from Sunday skips Saturday and counts Friday. Subtracting zero returns the original date.
