WORKDAY.INTL function
Summary
Returns the serial number of the date before or after a specified number of workdays using parameters to indicate which and how many days are weekend days
Syntax
WORKDAY.INTL(start_date, days, [weekend], [holidays])
The WORKDAY.INTL function syntax uses the following arguments:
• start_date Required. The start date, truncated to integer.
• days 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 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 weekend number values indicate weekend days as shown below.
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
Weekend string values are seven characters long. Each character in the string represents a day of the week, starting with Monday. The character 1 represents a non-workday and 0 represents a workday. Only the characters 1 and 0 are permitted in the string. Also, 1111111 is an invalid string.
For example, 0000011 would result in a weekend that is Saturday and Sunday.
• Holidays 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.
• start_date Required. The start date, truncated to integer.
• days 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.
