PERIOD BETWEEN


Calculates the period between two date or dateTime objects. This function returns the number of full periods of the specified type between two dates or dateTimes. 


Valid types for period are:

  • SECONDS
  • MINUTES
  • HOURS
  • DAYS
  • WEEKS
  • MONTHS
  • YEARS


Syntax

period BETWEEN date1 AND date2


Inputs
  • period - A keyword that specifies which time unit to return. Valid units are DAYS, WEEKS, MONTHS, YEARS, HOURS, MINUTES and SECONDS
  • date1 - The date or dateTime value that represents the start date.
  • date2 - The date or dateTime value that represents the end date.

You can use the periods HOURS, MINUTES and SECONDS only if at least one of the dates is a dateTime object or expression. On the other hand, with the periods DAYS, WEEKS, MONTHS and YEARS, the time component of a datetime value is ignored. So possible combinations are: YEARS BETWEEN, MONTHS BETWEEN, WEEKS BETWEEN, DAYS BETWEEN, HOURS BETWEEN, MINUTES BETWEEN and SECONDS BETWEEN

The order in which the dates are placed is relevant. YEARS BETWEEN date1 AND date2 = 0 - YEARS BETWEEN date2 AND date1


Return type

  • integer

If you prefer a functional syntax, you can call these methods as: period_BETWEEN(date or datetime, date or datetime). For example:

  • YEARS_BETWEEN(TODAY, UserInput.Date) 

  • MONTHS_BETWEEN(TODAY, UserInput.Date) 

  • WEEKS_BETWEEN(TODAY, UserInput.Date) 

  • DAYS_BETWEEN(TODAY, UserInput.Date) 

  • HOURS_BETWEEN(NOW, UserInput.DateTime) 

  • MINUTES_BETWEEN(NOW, UserInput.DateTime) 

  • SECONDS_BETWEEN(NOW, UserInput.DateTime)

WORKINGDAYS BETWEEN

WORKINGDAYS_BETWEEN


Calculates the working days between two date or dateTime objects. It returns the number of full working days between two dates or dateTimes. The default working days are Monday, Tuesday, Wednesday, Thursday and Friday. This default can be overridden by supplying a list with alternative working days.


Syntax

WORKINGDAYS BETWEEN startDate AND endDate
WORKINGDAYS_BETWEEN ( startDate, endDate, workingDays )



Inputs

  • date1 - The date or dateTime value that represents the start date.

  • date2 - The date or dateTime value that represents the end date.

  • workingDays - A list containing alternative working days. Note that the days should be specified as returned by the DAYOFWEEK function, e.g. Sunday = 1, Monday = 2 etc.

The order in which the dates are placed is irrelevant. WORKINGDAYS_BETWEEN date1 AND date2 = WORKINDAYS_BETWEEN date2 AND date1. Also note that the time component of a datetime value is ignored, similar to the DAYS BETWEEN function.
