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.

- MONTHS
- YEARS
Syntax
period BETWEEN date1 AND date2

DAYS
,WEEKS
,MONTHS
,YEARS
,HOURS
,MINUTES
andSECONDS
- date1 - The date or dateTime value that represents the start date.
- date2 - The date or dateTime value that represents the end date.
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 irrelevant. YEARS BETWEEN date1 AND date2 = 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)
