How this calculation works

A project deadline in "business days" excludes weekends and federal holidays. This calculator adds the requested number of working days to your start date, skipping Saturdays, Sundays, and the 11 federal holidays.

Counting starts on the business day after your start date. This matches how most contracts and shipping estimates interpret "X business days from today."

Frequently Asked Questions

How are weekends and holidays handled?
The calculator adds only Monday–Friday days that are not federal holidays. It stops once the requested number of working days has been added and returns the resulting due date.
Does the start day count as a work day?
No — counting begins on the next business day after your start date, consistent with how "X business days from today" is typically interpreted.
