◧ Arguments

ArgumentTypeRequiredDescription
start_date Date Required The start date, truncated to integer.
days Number Required The number of workdays before or after the start_date. A positive value yields a future date; a negative value yields a past date; a zero value yields the already specified start_date. Day-offset is truncated to an integer.
weekend Number Optional If used, this indicates the days of the week that are weekend days and are not considered working days. The weekend argument is a weekend number or string that specifies when weekends occur. The 1 (or omitted) = Saturday, Sunday; 2 = Sunday, Monday; 3 = Monday, Tuesday; 4 = Tuesday, Wednesday; 5 = Wednesday, Thursday; 6 = Thursday, Friday; 7 = Friday, Saturday; 11 = Sunday only; 12 = Monday only; 13 = Tuesday only; 14 = Wednesday only; 15 = Thursday only; 16 = Friday only; 17 = Saturday only.
holidays Date Optional This is an optional argument at the end of the syntax. It specifies an optional set of one or more dates that are to be excluded from the working day calendar. Holidays shall be a range of cells that contain the dates -- or an array constant of the serial values that represent those dates. The ordering of dates or serial values in holidays can be arbitrary.

▣ Examples

Using a 0 for the Weekend argument results in a #NUM! error. =WORKDAY.INTL(DATE(2012,1,1),30,0)
Result: #NUM!
Finds the date 90 workdays from 1/1/2012, counting only Sundays as a weekend day (Weekend argument is 11). =WORKDAY.INTL(DATE(2012,1,1),90,11)
Result: 41013
Uses the TEXT function to format the resulting serial number (40944) in a "m/dd/yyyy" format. Finds the date 30 workdays from 1/1/2012, counting only Saturdays as a weekend day (Weekend argument is 17). =TEXT(WORKDAY.INTL(DATE(2012,1,1),30,17),"m/dd/yyyy")
Result: 2/05/2012

§ Remarks

  • If start_date is out of range for the current date base value, WORKDAY.INTL returns the #NUM! error value.
  • If any date in holidays is out of range for the current date base value, WORKDAY.INTL returns the #NUM! error value.
  • If start_date plus day-offset yields an invalid date, WORKDAY.INTL returns the #NUM! error value.
  • If a weekend string is of invalid length or contains invalid characters, WORKDAY.INTL returns the #VALUE! error value.

⚠ Common Errors

#NUM! If start_date is out of range for the current date base value, WORKDAY.INTL returns the #NUM! error value. If any date in holidays is out of range for the current date base value, WORKDAY.INTL returns the #NUM! error value. If start_date plus day-offset yields an invalid date, WORKDAY.INTL returns the #NUM! error value.
Fix: Use codes 1 to 7 or 11 to 17
#VALUE! If a weekend string is of invalid length or contains invalid characters, WORKDAY.INTL returns the #VALUE! error value.
Fix: برای weekend رشته هفت‌نویسه‌ای فقط با ۰ و ۱ وارد کنید (مثلاً 0000011) یا از عدد ۱ تا ۱۷ استفاده کنید؛ از 1111111 استفاده نکنید.
