Calculates the date after a specified number of workdays excluding specified weekend days and holidays.

Sample Usage

WORKDAY.INTL(DATE(1969, 7, 21), 4, 1, A1:A10)

WORKDAY.INTL(DATE(1995, 8, 13), -2, 2, B1:B10)

WORKDAY.INTL(DATE(1969, 7, 21), 0)


WORKDAY.INTL(start_date, num_days, [weekend], [holidays])

  • start_date - The date from which to begin counting.
  • num_days - The number of working days to advance from start_date. If negative, counts backwards.
  • weekend - [ OPTIONAL - 1 by default ] - A number or string representing which days of the week are considered weekends.
    • String method: weekends can be specified using seven 0’s and 1’s, where the first number in the set represents Monday and the last number is for Sunday. A zero means that the day is a work day, a 1 means that the day is a weekend. For example, “0000011” would mean Saturday and Sunday are weekends.
    • Number method: instead of using the string method above, a single number can be used. 1 = Saturday/Sunday are weekends, 2 = Sunday/Monday, and this pattern repeats until 7 = Friday/Saturday. 11 = Sunday is the only weekend, 12 = Monday is the only weekend, and this pattern repeats until 17 = Saturday is the only weekend.
  • holidays - [ OPTIONAL ] - A range or array constant containing the dates to consider holidays.


  • WORKDAY.INTL does not auto-convert number formats in the same way that Excellentable does upon direct entry into cells. Therefore, WORKDAY.INTL(10/10/2000,4) is interpreted as WORKDAY.INTL(0.005,4), where the provided date is the quotient of 10 divided by 10 divided by 2000.

  • WORKDAY.INTL calculates a number of working days after a given date. To calculate the number of working days between two dates, use NETWORKDAYS.INTL.

  • WORKDAY.INTL works similarly to WORKDAY but also allows weekend days to be specified (for areas where Saturday and Sunday are not considered the weekend).
