yearsBetween

yearsBetween()

Overview

The yearsBetween() function takes startDateTimeValue and endDateTimeValue as arguments. It returns the number of years between the given date-time values.

Note: The difference between yearsBetween function and yearsDiff function is that the yearsBetween function considers a year as 365 days. So, let's say the start date is specified as 02-Jan-2020 and the end date is specified as 01-Jan-2021, the yearsBetween function will return 1 (since the difference in days is 365). The yearsDiff function returns 0 in this case since this function considers a year depending on the number of days in it.
