The following dataset contains two columns of dates.

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

Transformation:

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

Transformation Name `New formula` `Single row formula` `datedif(Date1, Date2, day)` `'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` `Single row formula` `networkdays(Date1, Date2, [])` `'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` `Single row formula` `networkdays(Date1, Date2, ['2020-03-17'])` `'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` `Single row formula` `networkdaysintl(Date1, Date2, '1000011', [])` `'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` `Single row formula` `workday(Date2, -5)` `'workday'`

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

Transformation Name `New formula` `Single row formula` `workdayintl(Date2, -5,'0000111')` `'workdayintl'`
