**Contents:**

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.
- See DATE Function.
- See TIME Function.

- 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[,str_workingdays][,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.

- For more information, see DATE Function.
- For more information, see 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.

**Usage Notes:**

Required? | Data Type | Example Value |
---|---|---|

Yes | Datetime (Column reference or date output of DATE or TIME function) | `LastContactDate` |

### 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.

Examples:

str_workingdays | Weekend days |
---|---|

`'0000011'` | Saturday and Sunday (default) |

`'1000011'` | Monday, Saturday, and Sunday |

`'0000000'` | None. |

**Usage Notes:**

Required? | Data Type | Example Value |
---|---|---|

Yes | Array | ['1000011'] |

### array_holiday

An array containing the list of holidays, which are factored in the calculation of working days.

Values in the array must be in either of the following formats:

['2020-12-24','2020-12-25'] ['2020/12/24','2020/12/25']

**Usage Notes:**

Required? | Data Type | Example Value |
---|---|---|

Yes | Array | ['2018-12-24','2018-12-25','2018-12-31','2019-01-01'] |

## Examples

**Tip:** For additional examples, see Common Tasks.

### Example - Date diffing functions

**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. |

**Source:**

The following dataset contains two columns of dates.

- The first column values are constant. This date falls on a Monday.

Date1 | Date2 |
---|---|

2020-03-09 | 2020-03-13 |

2020-03-09 | 2020-03-06 |

2020-03-09 | 2020-03-16 |

2020-03-09 | 2020-03-23 |

2020-03-09 | 2020-04-10 |

2020-03-09 | 2021-03-10 |

**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'` |

**Results:**

Date1 | Date2 | workdayintl | workday | networkDaysIntl | networkDaysStPatricks | networkDays | datedif |
---|---|---|---|---|---|---|---|
