Overview

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

Note: The difference between monthsBetween function and monthsDiff function is that the monthsBetween function considers a month as 30 days. So, let's say the start date is specified as 01-Feb-2020 and the end date is specified as 01-Mar-2020, the monthsBetween function will return 0 (since the difference in days is less than 30). The monthsDiff function returns 1 in this case since this function considers a month depending on the number of days in it.
