The Excel WORKDAY function takes a date and returns the nearest working day in the future or past, based on an offset value you provide. You can use the WORKDAY function to calculate things like ship dates, delivery dates, and completion dates that need to take into account working and non-working days.
- start_date – The date from which to start.
- days – The working days before or after start_date.
- holidays – [optional] A list dates that should be considered non-work days.
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.
WORKDAY excludes excludes weekends by default, and dates supplied as holidays. 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.
