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'
