NETWORKDAYSINTL Function

Calculates the number of working days between two specified dates. Optionally, you can specify which days of the week are working days as an input parameter. Optional list of holidays can be specified.

  • Inputs can be column references or the outputs of the DATE or TIME functions.

  • The first value is used as the baseline to compare the date values.

  • If the first date value occurs after the second date value, a null value is returned.

Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.

Basic Usage

networkdaysintl(StartDate, EndDate)

Output: Returns the number of working days between StartDate and EndDate.

Syntax and Arguments

networkdaysintl(date1,date2<span>[</span><span>,</span><span>str_workingdays]</span>[<span>,</span>array_holiday])

Argument

Required?

Data Type

Description

date1

Y

datetime

Starting date to compare

date2

Y

datetime

Ending date to compare

str_workingdays

N

string

Seven-character string identifying the weekend days.

array_holiday

N

array

An array of string values representing the valid dates of holidays.

For more information on syntax standards, see Language Documentation Syntax Notes.

date1, date2

Date values can be column references or output of the DATE function or the TIME function.

Date values to compared in working days.

  • If date2 > date1, then results are positive.

  • If date2 < date1, then a null value is returned.

If date1 and date2 have a specified time zone offset, the function calculates the difference including the timezone offsets.

  • If date1 does not have a specified time zone but date2 does, the function uses the local time in the same time zone as date2 to calculate the difference. The functions returns the difference without the time zone offset.

str_workingdays

A seven-character string identifying the days of the week that are working days.

  • String value must be seven characters long and contain only 0 or 1 characters. All other values are ignored.

  • First character in the string represents Monday and last character in the string represents Sunday.

  • If the string is not specified, then a Monday - Friday workweek is used.

Example - Date diffing functions

This example demonstrates how to calculate the number of days between two input dates.

Functions:

Item

Description

DATEDIF Function

Calculates the difference between two valid date values for the specified units of measure.

NETWORKDAYS Function

Calculates the number of working days between two specified dates, assuming Monday - Friday workweek. Optional list of holidays can be specified.

NETWORKDAYSINTL Function

Calculates the number of working days between two specified dates. Optionally, you can specify which days of the week are working days as an input parameter. Optional list of holidays can be specified.

WORKDAY Function

Calculates the work date that is before or after a start date, as specified by a number of days. A set of holiday dates can be optionally specified.

WORKDAYINTL Function

Calculates the work date that is before or after a start date, as specified by a number of days. You can also specify which days of the week are working days and a list of holidays via parameters.

Transformation:

The first transformation calculates the number of raw days between the two dates:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

datedif(Date1, Date2, day)

Parameter: New column name

'datedif'

This step computes the number of working days between the two dates. Assumptions:

  • Workweek is Monday - Friday.

  • There are no holidays.

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

networkdays(Date1, Date2, [])

Parameter: New column name

'networkDays'

For some, March 17 is an important date, especially if you are Irish. To add St. Patrick's Day to the list of holidays, you could add the following transformation:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

networkdays(Date1, Date2, ['2020-03-17'])

Parameter: New column name

'networkDaysStPatricks'

In the following transformation, the NETWORKDAYSINTL function is applied so that you can specify the working days in the week:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

networkdaysintl(Date1, Date2, '1000011', [])

Parameter: New column name

'networkDaysIntl'

The following two functions enable you to calculate a specific working date based on an input date and integer number of days before or after it. In the following, the date that is five working days before the Date2 column is computed:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

workday(Date2, -5)

Parameter: New column name

'workday'

Suppose you wish to factor in a four-day workweek, in which Friday through Sunday is considered the weekend:

Transformation Name

New formula

Parameter: Formula type

Single row formula

Parameter: Formula

workdayintl(Date2, -5,'0000111')

Parameter: New column name

'workdayintl'
