The WORKDAY function figures out a date that represents the "nearest" working day N days in the past or future. WORKDAY can be used to calculate due dates, delivery dates, and other dates that should exclude non-working days.

Use a positive number for days to calculate future dates, and a negative number for past dates.

Note: WORKDAY does not include the start date date as a work day when it calculates the end date.

Weekends

By default, WORKDAY will exclude weekends (Saturday and Sunday) . If you need to customize which days of the week are considered weekend days, use the more robust WORKDAY.INTL function.
